W216 cl63 AMG break calipers down-grade vs W215 55?!?!?
I just inspected the brakes on my cl63 and to my surprise and shock the front calipers are nothing more then two separate one piston calipers bolted to one braket and fited with AMG covers that make it appear to be a 6 or 8iston caliper. WTF?... The rear is a much smaller one piston caliper, again with a AMG cover on the outside to make it appear like its a 2 or maybe a 4 piston caliper. What is this all about? Why did they not install the same 6 piston fronts and 4 piston rear calipers on these cars like the old cl55 cars had? I'm very confused about this right now.

the 60-0 distances for both car are pretty much identical (112-115 feet) and is limited by front tire contact patch vs. weight over tires (static + dynamic weight). stopping power is not the limiting factor.
on the other hand multi-piston calipers are more complex and more prone to sticking so the newer calipers are addressing this a bit. divide and conquer strategy is used in this case.
rear calipers are pretty much irrelevant as in emergency brake situations the rears are used strictly to keep the rear tucked going in the direction of the turn of the steering wheel (via abs + stability control). rear braking force is really not used for stopping purposes. in that sense simple dual piston (or even single piston- sliding type) calipers are sufficient.

Seems very cheap in my opinion. You don't see this type of brake set up on any other performance sedan. Every other line of AMG cars is using the big monoblock calipers. C, E CLS, SL etc. The car does top very well but I wouldn't consider this set up being a performance break set up by any stretch.
As far as
"on the other hand multi-piston calipers are more complex and more prone to sticking so the newer calipers are addressing this a bit. divide and conquer strategy is used in this case"
Ive had zero issues with any of my cars with 6-8 piston calipers. If anything this w216 set up is so much more to maintain then the w215 brake set up as far as replacement pads and rotors.

Even if they do work. Im sure everyone here would pick the 6/4 piston set up vs this crappy ****.

I understand that they work. What i don't understand of why AMG went out of their way to fit these cars with this set up VS every other model with the big monoblock calipers.

If MB made brake pads and calipers made of banana peels yet they stopped the car as well as the 6 piston calipers, I would be fine with banana brakes.

interesting discussion.
In this day and age, ppl are piston hungry….they believe more piston = better the stopping power…at least that's what we are lead to believe, right? LOL!!
I've taken apart calipers and rebuilt them….and the multiple piston calipers obviously have more moving parts. They also have much much smaller pistons.
The double single-piston design now employed on the CL63 are probably much bigger pistons compared to the CL55 6-pot caliper w/ smaller pistons. The stopping power is probably the same…just my 2 cents.
