Things You'll Need:
- Socket wrench with socket set
- Rubber mallet
- Zip-ties
- C-clamp
- Screwdrivers (flat head and Phillips head)
- New brake pads
- Tire wrench
- Jack with 2 jack stands
- Shop rag
- Brake parts cleaner
- Thread locker
- Torque wrench
-
Step 1
Loosen the lug nuts on the front driver's side by turning them counterclockwise 1/4 turn.
-
Step 2
Jack the Audi up off the ground using the factory jack point in the front and rear of the vehicle. These jack points are located behind the radiator (front) and behind the trunk, near the bumper (rear).
-
Step 3
Place a jack stand under each of the four pinch welds located in the front and rear of the TT under the car.
-
Step 4
Continue to loosen and remove the wheel lug nuts and pull the wheel off the wheel hub assembly.
-
Step 5
Loosen the upper and lower caliper mounting bolts and remove the caliper. It will still be attached to the brake system by a rubber brake hose. You need to secure the caliper to the Audi's coil springs with zip-ties so that you do not damage the brake line.
-
Step 6
Remove the brake pads from the caliper using a rubber mallet. Place the face of the old brake pad over the caliper piston and slide a c-clamp over the brake pad and caliper assembly so that tightening the clamp will force the pad against the piston. Tighten the c-clamp to force the piston back into the caliper, but make sure that the piston boot does not twist or rip. It should fold "accordion style" into the caliper.
-
Step 7
Insert the new pads with the curved side of the brake pad facing inwards toward the caliper. The tabs on the top and bottom of the brake pad should align with the retaining clips on the top and bottom of the brake caliper. Press the tabs on the brake pad into the retaining clips on the brake caliper.
-
Step 8
Reassemble the brake caliper. Installation/assembly is the reverse of removal.
-
Step 9
Spray the entire brake assembly down with brake parts cleaner. Wipe off any dirt or debris with a shop rag and spray the assembly down again to remove all traces of oil or grease.
-
Step 10
Install the wheel and tighten the lug nuts, then lower the Audi to the ground and torque the lug nuts to 100 lbs-ft. with a torque wrench. To do this, set the dial on the torque wrench to 100 lbs-ft. and turn the lug nuts clockwise with the torque wrench until the wrench clicks; this will indicate that the proper torque value has been reached.
-
Step 11
Pump the brakes to restore brake pressure until the pedal is firm.
