Is there an acceptable wear limit on brake discs?
A garage is always going to want to change them if they don’t think they will make it to the next service. Most manufacturers specify the acceptable wear limit of brake disks – its usually between 1 & 2mm inside whatever a new disk is – so ask for the spec & the measurements.
How long do brake pads and discs last?
Short story: The car was making grinding noise during braking, and when I took the car in and inspected it, they said the pads are all gone, and also require to change the discs (all 4!) 1) Should they have checked the brake pads and disc level during the service? 2) How long should I expect the disc to go for in a brand new car?
What does it mean when your disc brakes are out of alignment?
A vehicle with disc brakes slows or stops by applying pressure via brake pads to a rotor attached to the wheel hub. Brake pads that show uneven wear generally are out of alignment, and depending on the wear pattern this type of wear could mean a variety of things.
When do you know it’s time for a disc brake job?
Disc brakes generally give a few clear indications that it’s time for a brake job. The first is something you can hear: Once brake pads are worn to the point of needing replacement, a thin metal strip in the pads will make a screeching noise or squeal when you apply the brakes.
What are the wear limits on a 19.5 inch brake disc?

Why are disc brakes better than friction brakes?
Disc brake technology was developed further at BPW’s initiative. The wear and crack resistance of the brake discs and pads has been improved. This means modern disc brakes can be operated in comparatively higher temperature ranges, and achieve long service lives at the same time.
