- Small screwdriver, carefully remove the inner edge of the boot 7 (see. Fig. 8.22) out of the groove of a support cylinder, taking care not to damage the piston;

- With a special key 3131, remove the piston from the cylinder by turning it counterclockwise. When the piston takes a position in which it is free to rotate, but will not go further out and remove it by hand;

- Small screwdriver to remove the O-ring groove 9 of the cylinder, acting very cautiously, so as not to damage the cylinder bore;

- Remove the guide pins of the guide pad 6 and remove the rubber protective covers 5.

The assembly of a brake disc cylinder mechanism of the rear wheel spend in reverse order, thus:

- Thoroughly clean and check all parts of the brake mechanism. If the cylinder and the piston are in good condition, use the repair kit for assembly. It is recommended that the O-ring of the cylinder and replaced with new boot;

- Lubricate the piston, cylinder bore and a new O-ring piston with clean brake fluid;

- With a special key 3131 or steel strips, screw the piston in the brake cylinder. During screwing uniformly apply pressure to the piston. This outer working edge of the anther enter into the groove of the piston, as will be in front of him;

- Apply to the bleed screw drive brake grease and wrap it;
