Do yourself, your wallet, the environment? a favor and get that storage coating off the rotors with hot water and laundry detergent. Fill your laundry sink with enough very hot water to cover a rotor, add a measure of detergent, grab a scrub brush and go to it. Only takes a minute on each side. Then rinse thoroughly with the hotest water you can stand and watch as within a minute the rotors are dry and clean enough to eat off of. It's magic.

I've been doing all my brakes for years. One thing to add to your list of to do's is be sure to put blue locktite on all the bolts before you put everything back together. That would suck to have a caliper come off down the road. To change out the pads alone on these things could not be easier. They are like the Brembo's on my Jeep SRT8. Knock out the 2 slider pins with a hole punch, pull out the old pads, slide in the new and put the sliders and guide back in. Done. Also, another little tip. See how he has his calipers sitting on the floor. Before you get started at this job get some big zip ties. You can zip tie the caliper to anything so that you don't take a chance of scratching your nice calipers and so that you don't brake a brake line.

Yes. First you must disable the SBC system and relieve the system pressure. Then you remove the pads by tapping out the pins and sliding out the old pads. Then you press the caliper pistons back into the calipers (best to crack open the bleeder screws to do this), close the bleeders when the pistons are fully depressed, then apply the anti-squeal paste of your choice to the pad backing plates, insert the pads, replace the pins, and you're good to go. Don't forget to observe any pad break-in requirements specified by your pad manufacturer.

Why do you need to scrub the new rotor ? Wont the new pads pull the coating off the first time you hit the brakes ? I have never done this on any other brake changes I have done.

I am looking for some help with the "how to" for disabling the SBC system for a 2005 C55 AMG. I desparately wan to change the front brake disks and pads, but I am concerned about the SBC system. Any advice?

Is the SBC pump the device pictured in this thread? I checked the component under the hood that looks similar and it is labeled ESP. I presume there is an electronic connector I should disconnect? I have also read notes on not opening doors and leaving all electronics off. What does the SBC do? Is it going to prevent me from being able to open the caliper to install new pads? ........sorry for all the questions, this is new to me. Thanks.

I received various message to my request for information on the SBC system. We reader informed me that the C55 AMG did not have it. Due to the conflicting information, I contacted MB USA, gave my vin number and confirmed that no C class (including the AMG) has the SBC braking system. I can not say that includes your CLK 55 AMG. But, that is a call to make to determine if your car has it.
Thanks to those that took the time to respond; it helped.

BUMP! few newbie questions from, well, a noob! lol, now to the Q's.
1. When you have to push the pistons back in, its suggested that its wise to loosen the bleed nipple and let the extra brake fluid out. is the bleed nipple the torx looking nut on the face of the calipers?
2. how important is it to clean the coating off before install?
3rd and last. how do you bleed the brakes/ and is it necessary?
l am looking at brakes in about 7k miles and am Not having the dealer rip me off. TIA- John

I was told by my tech, there is no need to disconnect SBC. Just leave the doors closed and u will be fine, while changing pads.

Asides looking at the pads themselves, or feeling the need to change brakes/rotors do Mercedes cars computer tell you the brakes need to be changed like the BMWs?
So when you disconnect the sbc pump, the calipers release all the tension on the pistons automatically?

Yes, I believe there are sensors on the brakes that communicate with the FSS, and disconnecting the pump does not relieve pressure, it just prevents them from locking up all of a sudden and taking off your fingers.

I will be attempting this soon. How do you check to see if your rotors are still in spec?
20k miles ago, the dealer rated them excellent, but my pads are pretty low and hopefully I'll just be putting in EBC reds.

The most common spec associated with brake discs is the remaining thickness of the disc. Normally, the minimum thickness of a particular disc is stamped on the outer lip of the disc. To measure, you need a brake thickness micrometer. Here's an example:

These come in all price ranges; find one that suits your budget.
