GT systems are revolutionary in their design and performance, and no other braking company has been able to offer this level of performance, range of configurations, and sheer number of applications. The GT systems exemplify Brembo's dominance as a world leader in high performance braking as an OEM supplier to a winning partner in motorsports.

Brembo engineers design each brake upgrade specifically for your vehicle and driving conditions. Optimum brake balance is achieved by combining Brembo's thorough knowledge of OEM braking systems and use of an unlimited range of caliper, piston, and disc combinations. Brembo brake upgrades are easy to install and designed to work seamlessly with your vehicle’s stock master cylinder, ABS, and traction control system.



Calipers
Most OE calipers are of a sliding design, with piston(s) only located on the inboard side of the disc. While this type of caliper is inexpensive to manufacture, it is generally extremely heavy, and inherently flexible under braking, which significantly degrades performance. Conversely, Brembo's calipers are a fixed radial or axial mount design with opposed pistons and constructed from aluminum alloy. Despite being much larger and many times stiffer than the sliding OE caliper, they are also much lighter which benefits overall vehicle dynamics.






The caliper body has been designed to be as light as possible while meeting stiffness criteria.


Calipers are available in the standard colors of black, silver, red and yellow. Dedicated track enthusiasts will want to stick with black as this is the most durable color.


Each Brembo system is delivered with preloaded calipers. Brembo calipers are equipped with unique pad retaining features and sequential piston bores in order to provide even pad wear and optimum performance. Quick Release Pad Retaining System: Incorporates anti-rattle feature (pictured) to eliminate noise and is designed for quick and easy pad changes.


Brake pads
Brake pads are selected vehicle specific for high performance.


The GT-R option
The Mercedes C63 AMG kit is available in the GT-R option. GT-R stands for Grand Turismo Race and monobloc calipers are machined entirely from billet with a nickel plated race finish to provide both the features and benefits of a racing brake system. This includes improved stiffness and thermo-mechanical resistance which is critical in high-performance applications.




GT-R's twin seal design provides race level performance without compromising the low maintenance aspects of a Brembo OE system. Ventilated stainless steel piston inserts are incorporated for heat rejection. The unique recessed dust seal design provides increased protection at elevated brake temperatures....another Brembo innovation.



Caliper Mounting Brackets
All Brembo caliper mounting brackets are designed vehicle and system specific. They are precision milled from superior quality billet materials to ensure a precise fit and meet the strength requirements of high performance driving conditions. Brembo brackets are also further analyzed and tested to ensure fatigue life.

Brembo caliper mounting brackets are also anodized to provide an attractive finish.

Each Brembo system includes all necessary hardware for ease of installation (please read instructions prior to installation).


Part numbers are clearly laser etched along with an unique serial number (S/N) for each part.

Pictured, are a few examples of axial and radial mount bracket designs.


2-Piece Disc
Superior metallurgy and exceptional engineering allow Brembo discs to exceed in the most demanding conditions. Their advanced cast iron alloy lasts longer than any disc in the high performance and racing market.

Brembo's properitary floating hardware system permits a specific amount of radial and axial float which allows the disc to grow independent from the bell, averting thermal distortion when subjected to extreme temperatures. It also preloads the disc assembly to prevent premature wear and eliminate noise during street use.

By manufacturing the center section out of precision milled billet aluminum, a great deal of weight can be saved in this key location. This reduces both unsprung and rotating weight which benefits handling, acceleration overall vehicle dynamics.


DISC THERMAL CAPACITY
A. Mass: The area located in the outer ring of the disc (shown in orange), dictates thermal capacity. This consists of annulus, width, diameter, air gap, and vane design.
B. Annulus: The area between two concentric circles. This dimension directly correlates to the friction surface area of the brake pad.
C. Disc Width: The overall thickness of the disc. Calipers are designed for a specific width.
D. Air Gap: The area located between the rotor plates surface is airgap. The amount of airgap is a crucial factor in channeling airflow.
E. Vane Design: Exclusive venting system that improves cooling capacity which increases resistance to brake fade.

Brake systems are designed to operate best within a prescribed temperature range. While modern high performance friction materials broaden this temperature range, it is critical that the brake disc in a system has adequate thermal capacity.

Thermal capacity, or heat storage capacity, is determined by how much weight or mass is located in the outer ring section of the disc. This is the area where the friction surface of the disc meets the internal vanes (orange colored area in the diagram shown). The more mass located in this area, the more thermal capacity a disc has.



CROSS DRILLED
• Cross drilled discs run at slightly lower temperatures due to added air flow through the surface of the disc where heat is generated.
• They are also highly effective in wet conditions and shedding debris from the disc to ensure a clean braking surface.
• Improve pad “bite”, improve wet weather performance, continuously refresh the brake pad

SLOTTED DISCS

• Slotted discs are recommended when using race pad materials or compounds. the vehicle is submitted to extreme braking duties such as towing or hauling heavy loads.
• Improve pad “bite”, improve wet weather performance, continuously refresh the brake pad



Type V and Type III discs are an option for enthusiasts seeking to improve rotor longevity.


AIRFLOW/COOLING

The curved vane disc is directional, and curved vane disc must be installed with the vanes running back from the inside to the outside diameters in the direction of rotation. Orienting the disc in the manner creates a centrifugal pump. The rotation of the disc causes air to be pumped from the center of the disc, through the vanes, and out through the outside diameter of the disc. This greatly enhances the disc’s ability to dissipate heat. Additionally, all of Brembo’s slotted discs are directional, regardless of the vane geometry. The discs should be installed such that the end of the slot nearest the outer edge of the disc contacts the pad first.

TECH NOTE: It is a popular misconception that the cross drill pattern determines the direction of rotation of the disc. In truth, for an internally vented drilled disc, the geometry of the vanes dictates the direction of rotation.




HARDWARE

The coupling between bell, rotor and bushing has been carefully studied by Brembo to prevent performance and comfort problems by defining the correct tolerances for all components and the proper tightening torque.


HOW IT WORKS

During braking, torque is transmitted from the disc to the bell through a fastener called a bobbin. This type of mounting system is designed to allow a specific amount of float in both radial and axial directions. This allows the disc to expand and contract under high temperature which reduces stress and increases longevity of the related components.

Brembo's unique anti-rattle disc hardware utilizes a spring fastener in order to slightly preload the assembly which eliminates the noise generally associated with floating discs.




The floating 2-piece anti-rattle disc hardware system, commonly used in high performance braking systems, was actually developed by Brembo back in the mid 90's.

This innovation was initially engineered exclusively for the McLaren F1 supercar which is why the hardware is often nicknamed the "McLaren" spring.


Stainless Steel Brake Lines
Each Brembo GT kit includes a set of stainless steel brake lines manufactured by Goodridge. Goodridge is the leading line supplier to OE manufacturers and championship winning race teams worldwide. With the tightest bend radius in the industry and the lowest rate of expansion, you can be assured that every inch of pressure from the pedal is transfered directly to where it counts - the caliper. Goodridge is the only brake hose system approved for use in every country in the world and it's guaranteed for life.



Goodridge High Performance Brakeline race-bred street brake lines are constructed from the finest quality hose, consisting of a PTFE inner hose covered by braided stainless steel. In addition to providing a more responsive and firm brake pedal by eliminating the “spongy” feel that often accompanies stock rubber brake lines, High Performance Brakelines are abrasion and corrosion resistant to stay good looking for a long time to come.

Looks like a very comprehensive bit of gear.
Does this conversion include rears as well. The reason that I ask is that I would've thought that with increased braking efficiency on the front, you'd need a similar improvement on the rears to maintain the OE brake balance.
Cheers, Pickles.

 

Brembo has 3 kits available for your car. Two front kits and one rear kit. The two front kits come with the same 6 piston forged monoblock caliper but you can choose the 380mm disc or the 405mm disc. The rear is 4 piston caliper set up with a 345mm disc.

 

Thanks for that info.
Cheers, Pickles.

 

I can vouch for Brembo. Been using it for a very long time and it's just great stopping power. Could only imagine the GT-R kit.

 

We've had a good number of Brembos installed at the shop lately. Will your car be the next to get a set? Whether installed here with us or at your local shop, you can't go wrong with some Brembo braking power.

 

How are these an improvement over the factory brake hardware?

Thanks.

 

^ this. We do have brembo braking system from stock (6 pistons F, 4 rear).
The calipers look similar. The only difference seems to be the discs and pads.
Am i right?

 

Those were my thoughts as well man. I realize the rear rotors are smallish on the stock setup but that hardware up front is pretty substantial.

 

This is probably the most popular question we get asked. I will break down the major components and explain the differences.

Brake Calipers - The Brembo caliper is forged and the factory isn't so it's lighter which means better cornering. The Brembo caliper has different internals to with stand higher temps for cars tracking their vehicles and this is important because the C63 is not a light car. The Brembo caliper can also take a larger brake disc for more stopping power and better looks Most Calipers are available in Black Red Silver and Yellow and custom colors are available for $275 per caliper all done by Brembo before they ship.

Brake Discs- The material that Brembo uses in their discs are superior in ever way. For clients driving their cars on the street they will notice much better stopping power because the brake discs are lighter than the factory. They last longer as well. The the outer brake discs rings are cheaper to replace than the factory brake discs when they are ready to be be replaced. You can get the Brembo discs are available in slotted pattern which are quiet enough for the street and have the higher thermal capacity to run 20 minute DE sessions to multiple hours of endurance racing.

Brake Lines - Each GT and GT-R Brembo big brake kit comes with Stainless Steal Brake lines which will not expand when your brake fluid heats up which helps against brake pedal loss which is a huge safety concern.

I hope this answered your question. If you have any others please don't hesitate to contact me directly.

Please see my response below. On the outside everything looks very similar but there are some major differences.

Happy

 

Thank you for the very thorough (and prompt) reply. Definitely learned something.

Now, I definitely understand that the Brembo caliper that you are offering is forged whereas the factory caliper is not.

However, I was under the impression that the factory calipers are also Brembo calipers (they merely have AMG branding).

So, is it a situation in which the factory calipers are Brembos but a lesser model or is it a situation in which the factory calipers are not Brembo-made?

Thanks again.

 

Well...

I know that the calipers on my E63, the CTS-V, and the 2014 Corvette use nearly identical Brembo Calipers.

I would be interested to know how the metallurgy is different on the aftermarket that the stock rotors. Which version of grey iron are they using?

1. Stainless brake lines... Understood.
2. Unknown disk material
3. Vanes correctly set for rotation, which is better than stock. I am pretty sure left and right have one part number.
4. Calipers, just can't see the advantage. Now put titanium pistons, and that would be a real upgrade on the calipers.

 

How many miles until they wear out ?

The stock discs didnt last 30k KM ...

And i never track the car just drive it hard

 

Its not just the materials of the disc, it is also the size and thickness of the discs. Brembo discs in their GT and GT-R kits typically have a wider annulus aides in higher thermal capacity and better cooling. I have enclosed a link for some really awesome reading material that I urge anyone that has a thirst for brake knowledge read this.

It explains every little item including in their kits.

This is really impossible to predict because everyone's driving habits and conditions are different but they will last longer than OEM. I have had their brakes in most of my cars in the past and can attest to this.

 

Um... nice sales pitch, but I am afraid you're mixing up your apples and pitchforks, not just oranges. Don't get me wrong, I am wholeheartedly agreeing with you that having better brakes is important (particularly for motorsport applications), but there is so much bull and incorrect information in your "explanation" above that it's laughable. At the very least, try to understand what the different bits and pieces do and what they contribute to the whole picture before you try to explain it to the rest of us. If you sell brake kits, the very least you can do is learn how they work and what the individual pieces do. Providing the wrong explanation is worse than not providing one at all.

 

+1

I saw this post a few months back...glad Diabolis called it out for what it is. I think the irritating thing about it is that you are mixing marketing jargon for street/race applications to get a sale. The C63 does in fact have the GT application or some Brembo derivative...there are no gains to be had here. Maybe SS lines but still that is debatable...the GT-R is an upgrade that does in fact have forged calipers as the GT are cast. The cost of those calipers is in the stratosphere...so not worth it unless you gut your C63 and plan to track it every weekend and even then you are talking minimal gains. On top of the fact you would likely need a dual master cylinder setup or larger master cylinder to get all that the calipers have to offer - its a system and needs to be matched as such. It does help with unpsrung weight and overall vehicle dynamics but to say it makes you "corner better" ???

So the irritability part - posting something like this to unsuspecting or unknowing owners - mixing the jargon is bad advertising. If someone bought the GT system thinking they are getting an upgrade it is basically like a caliper color swap - only. I would be pretty pissed if I took off the same calipers and replaced them with the same calipers - only to get a different color.

I drive a 911 on the track that has a Brembo BBK on it - but with that I had to upgrade the master cylinder, pedal cluster, lines etc to get the benefits...on the track brakes or more important than HP, so I am very familiar with the workings of them...piston bore, thermal reserves and capacity and brake torque are all things of interest to me.

In summary I am just saying you should be very specific in terms of what you are pitching, what we have (C63 wise) and what a true "upgrade" is.

 

Is someone riding 16 inch Brembo discs under 19 inch rims ?

I´m on OZ Ultraleggera HLT and this might possibly work but till now nobody could say exactly if there is a fit

 

The sls ceramics are 402mm/15.83" rotors and are a very tight squeeze on the factory 19" wheels. That wheel design looks like it could fit (no mega lip/deep dish 3 pc wheel etc..., but i can tell you most 19"s will not be able to fit them. Maybe try and find an sls with carbon ceramics to test fit? probably not going to be easy to find someone willing but just throwing it out there. Unless you are already experiencing brake fade i doubt you'll notice a difference, id personally go carbon ceramic over these anyways. Try to stay away from going 20" wheels as they dont have much for tire selection.

 

16" rotors are huge. It is extremely unlikely that they would fit under 19" wheels as that would leave less than 1.5" for the rim itself and the brake caliper. As roadtalonsi said, I seriously doubt that you'd notice a difference though. If you're tracking the car and experiencing brake fade, I'd start by putting in better brake fluid and maybe going to the BS rotors on the front instead.

 

Not only are they huge they are heavy - and the worst kind of heavy is unsprung heavy, effects handling and acceleration.


The C63 is a lightweight car by most standards (with enormous brakes) - if you are overheating rotors on the track with upgraded pads/fluid...you may want to think about some performance driving tips...? You may be overdriving the car a bit.


Stock brakes and pads should be fine for some hot lapping at the track.

 

I didn't want to stir the pot, but you're 100% correct. The OEM brakes on the C63 are more than adequate even on a short, tight track. In my early days I have boiled the brake fluid on many cars, but it turned out it usually wasn't the car's fault, it was my driving. Some HPDE instruction and ATE Super Blue is all that was needed.

 

Exactly - nobody wants to hear "learn to drive" and there is no real way to say it delicately, especially in a car forum...but there are instances time and time again where pro-drivers beat on these cars at the track in stock form and rave about brakes etc...lap after lap. No fade, no issues. I think the most recent was the R&T compare with the 507 and the RS-5.


If you are looking for a BBK for looks on the street - that's cool too, everybody has their thing, just be aware that adding monster brakes and bigger wheels really cut into your overall handling/performance levels.

 

This thread is old however I have a 2010 sl600. I am not sure what size the standard brakes were but they caught fire after 4 laps around SPA F1 circuit so I decided to go to the Brembo BBK route. The first thing I would say is that the 405mm front brakes we're considerably lighter than the standard smaller brakes. And the 380mm rear showed the same results.
I returned to SPA and also Silverstone GP and had consistent strong braking throughout the day. My tires couldn't cope but the brakes were awesome.
Just wanted to give some first hand knowledge of the upgrade as their seems to be very little around. By the way I have no doubt that the stock setup is more than sufficient for road use however they cannot cope with consistent braking loads from high speeds.
