If there are any scoring marks, deep scratches, etc. on the working surface of the disc that increase pad wear and reduce braking efficiency, replace the disc.
In specialized workshops, such a disk can be turned and polished, but after processing, the thickness of the disk must be no less than the minimum permissible. Turning is carried out on both sides of the disk to the same depth.
You will need: keys "17", "12", screwdriver.
1. Remove the appropriate wheel.
2. Unscrew the two bolts securing the shoe guide to the steering knuckle and remove the brake mechanism assembly without disconnecting the brake hose from the working cylinder.
3. Hang the brake mechanism with a rope or wire to the front suspension spring. Make sure that the brake hose does not get twisted.

4. Clean the brake disc from dirt. Apply a liquid like WD-40 to the joints of the disc with the hub and to the guide pins. Wait a little, let the rust dissolve.
5. Unscrew the two guide pins and remove the brake disc.
Note: If necessary, knock off the disc with a rubber or plastic hammer.
Blows should be applied as close to the center of the brake disc as possible.
6. Install the brake disc in the reverse order. If you are installing an old disc, use a file to remove the ridges formed by disc wear on both sides.
