Over the past 4 weeks my E AMG Line has developed a vibration when braking, I know the E is prone to this issue.

the car has 56k on the clock, it’s been an intermittent issue for many months, but it was very faint.

Over this past few weeks it’s been quite pronounced! Over 50mph-70mph is where it’s felt, there no feeling in the brake pedal or steering wheel, it’s through the car seat and it’s when you apply the brake pedal with very gentle braking to normal braking.

Driving the car from cold is fine, it’s once the brakes have been applied and there’s some temperature in them that the issue starts.

If the front discs have warped, wouldn’t this be felt in the brake pedal/steering wheel?
 
Rear discs warped probably
 
That was my understanding, but not to sure how.

I have tried driving at higher speeds and doing several hard stops from 70mph-10mph to see if the discs had a buildup. But doesn’t really do anything.

Would a sticking piston or slider cause this issue? I am guessing no, as it would vibrate even from cold?

Thanks
