How to Replace Audi Brakes
1. Loosen the four or five lug nuts on one of the Audi's wheels using an Audi tire iron. Raise that wheel off the ground using a car jack.
2. Lower that side of the frame onto a jack stand to support the Audi. Remove the wheel from the Audi's frame, and set it aside while you work.
3. Remove the bolts from the rear of the brake caliper using a ratchet and correct-size socket from the set. Pull the caliper off the frame, and rest it on the lower control arm.
4. Remove the pads from the inside of the caliper by pulling them out. Insert an Audi brake compression tool into the caliper, and turn the handle clockwise to force the caliper's piston onto the caliper. Insert the new pads.
5. Place the caliper onto the rotor frame, and tighten the bolts to the torque specifications for that model. Place the wheel onto the frame, and replace the nuts to the wheel. Lower the frame to the ground, and tighten the lug nuts to the torque specifications for that model.
