Withdrawal
1. Remove the front wheels and fix the brake disc with the wheel bolt (see arrow in illustration).
4.1. Secure the brake disc by screwing in one wheel bolt (see arrow)
2. Unscrew both caliper mounting bolts with a socket wrench (see arrows in illustration 4.1).
3. Disconnect the plug of the brake pad wear sensor.
4. Release the plug from the holder by prying with a screwdriver and at the same time turning it 90° (see illustration).
4.4. Release the plug from the holder by prying with a screwdriver and simultaneously turning it 90°
5. Compress the upper and lower parts of the clamping spring alternately with an adjustable wrench, move them to the side and release them from the mount (see arrows in illustration).
4.5. Release the clamping spring from the mount with an adjustable wrench
6. Press the piston deep into the wheel cylinder with a flat screwdriver, and move the caliper outward (see arrows in illustration).
4.6. Press the piston deep into the wheel cylinder with a flat screwdriver, and move the caliper outward (see arrows)
Attention! If there is a high level of brake fluid in the reservoir, then when the piston is pressed in, it may splash out, so it is recommended in this case to take a certain amount of fluid from the reservoir.
7. Remove the outer brake pads from the caliper by prying them out with a screwdriver to disengage the tabs on the pads (see arrow in illustration).
4.7. Remove the outer brake pads from the caliper by prying them out with a screwdriver (see arrow)
8. Move the caliper in the direction shown by the arrows until it stops, carefully push the inner brake pads out of the cylinder cavities and remove them from the caliper (see illustration).
4.8. Move the caliper in the direction shown by the arrows
Installation
9. Clean dust and dirt from the caliper, and from the edges of the brake disc - possible rust. If the pads are serviceable, clean them with a wire brush and rags.
10. Check the brake disc for cracks, wear or mechanical damage and replace if necessary.
11. Measure the thickness of the brake disc.
12. Install the upper and lower inner brake pads with a wear sensor in the caliper and secure them in the cylinder cavity by inserting the protrusions on the pads inside, preventing damage to the cylinder cuff. Fasten the wear sensor wire in the holder (see arrows in illustration).
4.12. Install the inner brake pads with a wear sensor into the caliper and secure them in the cylinder cavity by inserting the protrusions on the pads inside (see arrows)
13. Move the caliper all the way out, remove the protective film from the outer brake pads, install the pads in the caliper and fix with a spring (see illustration).
14. Unscrew the wheel bolt that secured the brake disc.
15. Depress the brake pedal several times until it stops, so that the new brake pads self-adjust.
