Need some help chaps.
Been hearing an annoying rotational noise coming from the rear offside wheel so took it into Audi and they sent me an AudiCam video.
Car was up on the ramp and the technician span the wheel with his hand and it stopped at the same point on every turn. The diagnosis from Audi saying "rear brake pads + discs have high spots / some corrosion, this is the cause of the friction noise”.
They recommended I change the discs and pads to stop the noise.
However the question is, Why is this happening? The car has done 18,000 miles. There are no lips on the disc. There is no excess wear on the discs. They told me there is 80% material left on the pads.
The video would suggest either a warped disc or the caliper not releasing far enough?
If I were to change the pads/discs as recommended, whilst it will stop the rubbing noise neither components are showing excess wear, so why change them?
If they’re being changed because the disc is warped, then why has this happened (considering the other three brakes are working perfectly)?
I went out today for 30 minutes of driving with moderate to hard braking to see if the disc would clean up but you can clearly see from the images that the rear offside disc is an indication that something is not right.
My biggest concern is that with this being a braking component, it is now a safety issue and there is an underlying issue here, which needs to be identified.
My initial thoughts are that the caliper is at fault and therefore a warranty issue? Any idea's?
