C43 AMG pulsating brakes

[ukcolonel]

C43 AMG intermittent pulsating brake feeling --not grating or noisy --but uncomfortable feeling. One year old 4 000 miles

if its just pulsing with no noise Id be thinking warped discs....you need to check for run out.....even just jacking the wheel up and spinning them one at a time any measurable run out should be noticeable. Its low miles.....but I've seen new discs warp.

EDIT....Is it the car or the discs that are 4000 miles old?

Many thanks for your interest--It is 15 months old with 4k miles .
I have had it for 6 weeks. The pulsating seems to be evident when braking from speed ,not really noticeable at low speeds in traffic.
Given its low mileage I guess it might have been sitting around .
I will implement your suggestion with my local tyre place.

Surely go back to the supplying dealer?

In my experience pulsing brakes is pad material deposits on the disc. Try a few high speed stops but don't come to a complete stop. I had to do this on my CLS after travelling around town for a few journeys. A quick blatt down the dual carriageway with heavy braking into the slip road cleared it up

My thanks for your interest --I am waiting for the dealer (100 mils away) to retunm my call.

In the meantime I will try the hard braking suggestion --
Excellent comments

Beware of getting any other garage to do any work on the vehicle without the knowledge and consent of the supplying dealer. They could use this as an excuse to not pay for any repairs.

Surely under MB new car warranty - wouldn’t need to go back to supplying dealer for this?

 

[ukcolonel]

Yes,still under warranty and have spoken with my dealer....if the issue continues they will come and collect car . I will report back

My thanks to all .

Warped discs, you can always check them with a dial indicator.

Warped discs can happen with new discs from excessive and cooling.

Thank you ,
MB member ,ALFAitalia suggested the same ,but I must admit with only 4K miles I assumed unlikley.
My dealer has asked for a formal description and will then recover the car to investigate.
