How to Change the Front Brakes on an Audi A4

1. Loosen the front wheel lug nuts. Turn the tire wrench counterclockwise to loosen. Give the lug nuts a 1/8 to 1/4 turn. Do not give the wrench more than a 1/4 turn.
2. Raise the A4 onto jack stands. These will be an extension of the frame behind the radiator. This is the front jack point you need to lift up on with the jack. Put jack stands under the front pinch welds of the A4 and lower the vehicle onto the jack stands. Remove the wheel lug nuts and pull the wheel off the wheel hub.
3. Loosen the caliper pin bolt located on the bottom of the caliper to the right of the lower mounting bolt.
4. Place the c-clamp over the caliper housing so that the screw-end of the clamp is flat against the back of the outboard brake lining and the fixed arm of the clamp grabs the back of the caliper. Tighten the clamp to force the brake caliper piston (which you cannot see at this point) back into the caliper assembly.
5. Remove the upper and lower caliper mounting bolts and slide the caliper off the brake rotor. Secure the caliper assembly to the coil springs above the brake assembly with zip-ties. Swing the caliper bracket up from the bottom (which you can now do because the pin bolt is loose) and remove the old brake pads.
6. Insert new brake pads. Note the position of the pads. The pads must be inserted so that the curved section of the pad faces in towards the caliper. Fit the tabs on the top and bottom of the pad into the retaining clips on the caliper bracket and close the bracket against the caliper.
7. Pull the old brake rotor off the wheel hub and install a new rotor. Cut the zip-ties and slide the caliper assembly back over the brake rotor and tighten the mounting bolts to 50 lbs-ft. with a torque wrench. Make sure to put a small bead of thread locker onto the caliper mounting bolts to prevent them from vibrating loose during normal driving.
8. Spray the entire brake assembly down with brake parts cleaner to remove any oils from your fingers, grease or other debris. Put the wheel back on the wheel hub, tighten the lug nuts and lower the vehicle to the ground. Torque the lug nuts to 75 lbs-ft using a torque wrench.
