How to Replace the Front Brake Pads on a 2000 Audi A6

1. Park the Audi on level ground. Turn off the engine, and pull the hood release lever. Move to the front of the A6, and lift the hood. Remove the master cylinder cap, located to the left of the engine, near the back of the engine bay. Remove half of the brake fluid from the reservoir with a poultry baster. Place the master cylinder cap, loosely, onto the container.
2. Loosen the lug nuts on the front wheels, with the tire iron. Place a jack under the frame at the front of the vehicle, and lift the front tires off the ground. Place jack stands under the front axles, and lower the Audi onto the stands. Move the jack out of your way.
3. Remove the tires, and lay them rim-side-up, to avoid scratching the wheels on the ground. Remove the retaining clips on the outside of the calipers, with pliers. Remove the two caliper slide bolts on the inner side of each caliper, with a 12-mm socket and ratchet. Lift the calipers from the caliper brackets, and rest them on top of the steering arm, above the brake.
4. Pry the brake pads on the right wheel hub from the caliper bracket with a flat screwdriver. Spray the bracket slots with brake-parts cleaner, and clean the area with a wire brush and cloth towel.
5. Apply a thin layer of anti-squeal brake compound to the back sides of the new brake pads. Slide the pads into the caliper bracket slots.
6. Place the channel-lock pliers on the caliper piston and the back of the caliper. Squeeze the piston into the side of the caliper, to allow ample space for the new brake pads.
7. Place the caliper back onto the caliper bracket, around the new brake pads. Screw in the two caliper bolts, with the socket and ratchet. Replace the wheel onto the wheel bolts, and screw on the lug nuts.
8. Move to the left brake, and repeat Step 3 through Step 7. Place the left wheel onto the wheel bolts, and screw on the lug nuts. Lift the front of the Audi, with the jack, and remove the jack stands. Lower the front tires, to the ground, and tighten the lug nuts with the tire iron. Move back to the engine compartment.
9. Remove the master cylinder cap, and place a funnel into the reservoir. Add brake fluid, as necessary. Replace the master cylinder cap, and close the hood.
