If you own an Audi, one of your responsibilities is maintaining your car. This includes maintaining your brakes. Brake failure can lead to serious injury or death for you and others, so you need to keep them well maintained. Unlike on many cars, the rear brakes on Audis are disc brakes (most cars use drum brakes on the rear wheels). Replacing the brake pads when they wear down will help keep your car operating safely.

Park the Audi on a flat piece of ground. Make sure that the emergency brake is engaged, and the car is in "Park" if it has an automatic transmission or is in second gear, if it has a manual transmission.
Loosen (but do not remove) the lug nuts on the rear tires.
Jack up the rear of the car. Place jack stands underneath the outer frame of the car, then slowly lower the car onto the jack stands.
Unscrew the lug nuts and take the rear tires off the car.
Pull the spring clip out of the caliper with a pair of pliers. The spring clip is the wire that holds the brake caliper to the caliper bracket.
Pry the plastic caps off the 7 millimetre hex screw sockets on the back of the brake caliper with a flathead screwdriver.
Unscrew the two hex screws, then remove the caliper from the caliper bracket.
Remove the outer brake pad.
Push the piston back into the caliper with a C-clamp. You need to do this, because the new brake pads are thicker than the old pads.
Remove the inner brake pad.
Clean the brake caliper with brake wash. Place a drain pan underneath to catch the brake wash.
Apply brake grease to the slider bolts.
Install the brake pads onto the caliper and secure it with the 7mm hex screws. Place the plastic caps onto the hex screws.
Slowly lower the caliper over the caliper mount.
Put the tire back onto the wheel hub and secure it with the lug nuts.
Jack the car up off of the jack stands. Remove the jack stands and slowly lower the car onto the ground.
Tips and warnings
- Wear gloves and safety goggles and avoid coming into direct contact with the brake dust when working on the brakes because the brake dust may contain asbestos.
