Overview
Matched to a 2015 Audi A4 Premium Plus rear-brake job with the B8.5 platform and electronic parking brake hardware.
Rear service differs from a generic brake job because the parking-brake motor must be released correctly before piston compression.
If your car is quattro or uses larger wheel packages, confirm rotor diameter and pad shape before ordering parts.
Likely Causes
Rear pad wear indicator triggered or pad material is close to minimum thickness
Scored or lip-heavy rear rotors that should be replaced with the pads
Sticky rear caliper slide pins or parking-brake hardware causing uneven wear
Tools Needed
Mechanic Cost
$420 to $780 for a rear-axle service depending on rotor condition and labor rate

Safety Notes
Do not force the rear piston back against an active electronic parking brake motor.
Support the caliper so the brake hose and parking-brake wiring are not hanging under load.
Verify a firm brake pedal and normal parking-brake operation before moving the vehicle.
Diagnosis Path
Step 1
Confirm the rear axle is the worn end and inspect rotor condition through the wheel before disassembly
Step 2
Scan the Audi parking-brake module or use the correct service procedure to release the electronic parking brake
