Replacing brake pads
WARNINGS:
- Do not press the brake pedal with the cylinder body open, otherwise the piston will come out.
- Be careful not to damage the piston seal and do not allow fluid to come into contact with the brake disc.
- If the brake pad linings show signs of corrosion or their rubber coating has begun to peel off, replace the linings.
- If the caliper is not being replaced or disassembled, there is no need to disconnect the brake hose. Hang the caliper on a wire so that the hose is not stretched.
1. Remove the master cylinder reservoir cap.
2. Loosen the lower guide bolt.
3. Fold the caliper up. Remove the pad holders, return spring (except for the AD22VF model mechanism) and gaskets.
The maximum and minimum allowable thickness of brake linings are given in the section "Data for adjustments and control".
The installation of the pads is carried out in the reverse order.

Monitor the fluid level in the tank, because when the piston is pressed into the cylinder, the fluid will return to the tank.
Checking the brake disc
Beating
1. Secure the disc to the wheel hub with at least two nuts (M12x1.25).
2. Measure the axial runout of the disc using a dial indicator. First make sure that the axial clearance in the hub bearing is within the permissible limits (see Chapter "Front suspension").
- Maximum permissible runout is 0.07 mm
3. If the runout exceeds the specified value, try to adjust the position of the disc on the hub by successively moving it one hole.
4. If the rearrangement does not give the desired result, regrind the disk.
Thickness
Measure the thickness of the disc with a micrometer at 8 points around the circumference. The spread of measurement results should not exceed 0.02 mm, otherwise the disc must be re-ground.
Maximum permissible disc thickness:
- CL22VD and CL22VE: - 16.0 mm
- CL22VF - 24.0 mm
Assembly
1. After placing the protective cuff on the piston, insert it into the groove of the cylinder, then install the piston.
2. Secure the cuff with a retaining ring (only in AD22VF model).
Installation
1. Attach the caliper assembly to the steering knuckle. Attach the brake hose to the caliper, positioning it between the protrusions (see picture).
2. Reinstall all removed parts.
3. Remove air from the hydraulic drive (see the relevant section of this chapter).
