Warning: Replace disc brake pads on both front wheels at the same time - never replace pads on just one wheel. Brake dust contains asbestos, which is extremely harmful to health. Do not blow it off with compressed air or inhale it.
1. Remove the cap from the brake fluid reservoir, drain approximately 2/3 of the fluid into a container and discard it.
2. Loosen the wheel nuts, lift the car and securely support it on stands. Remove the front wheels.
3. Carefully inspect the brake disc as described in Section 4. If treatment is necessary, remove the disc as recommended in Section 4.
4. Following the figures, starting with 2.4a, perform the procedure for replacing the pads.
2.4a. Using a clamp, install the piston back into the caliper hole so that the pads can easily come off the disc - remember that one end of the clamp should be on the plane next to the tip of the brake hose, and the other end (screw) should press on the outer pad.
2.4b. Unscrew the two caliper studs (arrows) securing it to the steering knuckle (you will need a special head for this).
2.4v. Turn the caliper with the bottom up and out of the brake disc (support the caliper with a piece of wire - do not let it hang on the rubber hose).
2 4z. When installing new pads into the caliper, carefully push the inner pad clamps straight into the piston until the back of the pad rests squarely on the front of the piston - insert the outer pad into the caliper as shown (make sure the locating tabs on the pad (1) fit into the corresponding support holes (2) in the caliper frame).
2.4i. Place the vibration damping spring on the outer shoe (1) under the upper arm of the steering knuckle so that the notches of the upper edge of both shoes are on the upper arm of the steering knuckle (2), then rotate the caliper downwards until the notches of the lower edge of the shoes are located on the lower arm of the steering knuckle (be careful not to pinch the brake hose when doing this).
2.4k. Apply silicone grease to the caliper studs and inside their insulators, thread the studs through the caliper body into the holes in the steering knuckle arms (first screw on by hand, then to the required tightening torque).
5. After installing new pads and tightening the caliper, install the wheels and lower the car.
Note: If for some reason the brake hose was disconnected from the caliper, the brake system should be bled as stated in section 11.
6. Fill the master cylinder reservoir with fresh brake fluid and slowly pump the brakes several times to seat the pads against the disc.
