Hi guys

I have a 2016 amg gts with CCB ,
The car has only 10k/km and i noticed the break pedal shakes a and also the steering wheel when I do a hard break at low speed 60-0 km/h , at that time i feel like the car is not breaking and i hear a sound like abs working or somthing is hard to explain it .

when i do hard breaks from 150km-0 it works better and nothing happen , so most of the time this happen only at low speed , if i break jently also nothing happen .

I dont know what is the problem exactlly because i dont track the car .

thanks guys for your help .

It sure sounds like a warped brake rotor or two. Your dealership or brake shop should be able to find the reason for the shake.

thanks for the reply , can you please explaine to me if the rotor is wraped like you said do you think it can be fixed or it need to be replaced ?
Also do you have any idea of it price in europe ?

I want to be informed before i take it to the dealer because its far from my town .

Brake rotors typically need to be replaced and not merely resurfaced to be safely free of warping and retain necessary thickness and integrity. Carbon ceramics tend to quite expensive...don't know costs...but you could try a search online. I hope I am wrong and it is something else and comparatively inexpensive.

thank you very much for your answer

Does warping apply to CCB? I thought it was a steel rotor thing.

Ok , this new answer make a smile on my face after checking the prices of the CC rotors .

can anyone else confirm please if the CCBs rotors can also get wraped or not ?

thanks

CCB rotors cannot warp; they are too hard and brittle for that. They will crack at best. There still might be a crack. Perform a visual. Get it inspected. And yes, CCB rotors are $11k or so for a full (4x) replacement. (That is why I got the steel edition.)

Thank you guys for the help

Sorry I passed along some old knowledge with steel rotors that I haphazardly applied. My mistake.

Make sure that you aren't washing the CCM rotors with strong soaps, or other detergents; they hate that.

Check your brake pads to make sure they aren't highly worn or tapered in any way; if so, replace.

It definitely sounds to me as WhiteBlack mentions, that you have an uneven deposition of brake pad material on the face of the rotor(s). You need to do a sequence of high speed decelerations to try and even out the pad material on the rotor face. Do not engage ABS and do not come to a complete halt.

If none of the above seem to work or be the answer, head to your local dealership as hopefully you're still in warranty.

Good luck,

Bish

thanks , i toke the car today to a garage to do an eye checking for the rotors and the brake pads and luckly there is no crack or anything , also the brake pads looks like new as the car has only 10k and it was never tracked .

Before i wrote this post here in the forums i did couple of hard brakes 150-0 i did it like 5 or 6 times , it is enough or should i do more to try to clean the rotor ?

i use couple of producs to clean like the tires shine spray and also for the rims , maybe i should stop sprayig directly ?
