Attention! Brake pads are changed only as a set for one axle. When cleaning the pads, dust and dirt should be removed by wiping with a rag soaked in denatured alcohol or a special liquid; blowing is prohibited.
1. Loosen the wheel nuts, lift the front of the car and place it on stands. Engage the parking brake. Remove the wheels.
2. Remove about 2/3 of the liquid from the tank using a syringe (to prevent spillage when moving the piston away from the pads). Clean the caliper and adjacent parts from dirt.
3. Remove the brake pads from each wheel separately. Use a clamp to move the piston away from the pad (see photo).
4. Remove the clamp.
5. Unscrew the two caliper mounting bolts (see photo).
6. Move the caliper away from the disc and remove the outer pad (see photo).
7. Remove the inner pad from the caliper (see photo). Secure the caliper with wire, keeping it out of the way to prevent damage to the brake hose.
8. Remove the mounting bolt seals, then use a sharp tool to remove the rubber bushings from the caliper (see photo).
9. Clean the caliper and mounting bolts and check their condition, corrosion and damage. Replace the bolts if corrosion or deformation is found. Inspect the brake disc. If necessary, grind the disc or replace it.
10. Install new rubber bushings and seals into the caliper (see photo). Fill the space between the bushings with silicone grease.
11. Install the inner pad with the bracket into the caliper so that the wear indicator faces the rear of the caliper.
12. Install the outer pad into the caliper so that the protrusion at the bottom of the pad fits into the recess on the caliper.
13. While holding the caliper in place, insert the mounting bolts through the bushings and into the caliper bracket. Tighten the bolts to the specified torque.
14. Install the brake pads on the second wheel, install the wheels and lower the car. Add fluid to the reservoir to the normal level.
15. Press the brake pedal several times to press the pads against the disc, then check the fluid level in the reservoir.
16. Before starting to drive, check the brakes. Avoid sudden braking until the pads have been worked in.
