Back Brake grinding at low speed

[SteveT]

Good morning, can anyone confirm if there is a problem with rear brakes

Bought a brand new Audi A3 from the main dealership in May.  Since day one I have had a squeak  and grinding noise on the rear brakes when running at low speed, less than 10 mph in traffic..

The car has been back into Audi three times .

First time mechanic test drove the car with me , said he couldn’t believe how noisy the brakes were , but said they was no problem…?

second time, they so called cleaned and re greased the rear brakes, which lasted about thirty miles

Third time dealership, said the pads had Glazed, of which they replaced, at no cost to me, but the noise was back within a couple days…???? 
 
I would much appreciate, if anyone could shed some light on this..? 
many thanks.

In your position I would demand, in writing, a replacement car on the grounds that the car is defective and the dealer has thrice proved himself incapable of fixing it.

It could be a long battle so keep records of all communications, which should preferably be written not verbal.

Afternoon Cliff, I much appreciate your advice, the car is currently booked to go in again to the main dealership on the 30th Dec ( the earliest booking) for further investigation, so I will keep you updated as we go…! Thanks again.

Please do. You are not the only one in such a position so it would help everyone to know of your progress.

The fact they admitted the pads were glazed probly without thinking about what they were saying points towards the calipers not backing of correctly after application, unless your driving with your handbrake on which obviously your not if you were to glaze your rear brakes your front would be even worse, typically it’s 70% braking force on front and 30% on back

Evening Sid, many thanks for your information and advice.

this is further questions I will ask at the dealership, when I take the car back in on the 30th.  I will keep you updated.👍🏻

Good morning all, the latest update I have at the moment is, the car went in again on the 30/12, the mechanic told me there is nothing wrong…!!!? Well, I thought I would now get a second opinion on this. I took the car to the same dealership, but at different location , they are now going to have the car for the day and investigate thoroughly on 9/1/25 , so I am hoping we can get to the bottom of this somehow.

Many thanks Steve,

Probably pessimistic, but be prepared that they will check the history and see your complaint has been disputed by the supplying dealer. 
Fore warned ….

Kind regards,

Gareth.
