2. Remove the plug from the brake fluid reservoir and seal the reservoir opening as indicated in section 6, paragraph 1. This will minimize fluid loss when disconnecting the brake hose.
3. Clean off any dirt from the inside of the backing plate and clean the surfaces around the brake hose nipple, bleed screw and 2 bolts securing the wheel cylinder to the backing plate (see photo).

4. Carefully disconnect the brake line from the hose and plug the open end of the line to prevent dirt from entering the system.
5. Unscrew and remove the 2 bolts securing the wheel cylinder. Unhook the upper tension spring of the brake pads and, moving the pads apart, remove the wheel cylinder.
5. If the cylinder has leaked and the brake linings are contaminated with brake fluid, they must be replaced on both rear wheels (see section 8).

6. Clean the outside of the cylinder with methyl alcohol and transfer it to a clean work bench for disassembly.
7. Remove the rubber boots from both ends of the cylinder and carefully pull out the pistons, cuff and spring. Pay attention to the location of the individual parts so that you can install them in exactly the same order later.
8. Inspect the inner surface of the cylinder for grooves, scratches, traces of corrosion, etc. If defects are found, the cylinder must be replaced.
9. If the cylinder is in normal condition, clean it thoroughly with methyl alcohol (do not use abrasive materials or scrapers that may damage the cylinder surface). After cleaning, wipe the cylinder dry with a clean, lint-free cloth.
10. Select seals from the repair kit that are exactly identical to the old ones and dip them in clean brake fluid before installation.
11. Lubricate the inside of the cylinder with clean brake fluid and install the spring, pistons and seals into it. Be careful not to damage the seals when installing them into the cylinder. Install the rubber boots onto the cylinder and wipe the assembled unit dry with a clean, lint-free cloth.
12. Installation of the wheel cylinder on the support disk is carried out in reverse order. Please note the following points:
- a. When connecting the brake line, be careful not to strip the threads of the line fitting.
- b. Install the brake drum (see section 7).
- c. Bleed the brakes and add brake fluid to the reservoir, remembering to remove the plastic film or plug with the sealed ventilation hole from the reservoir opening. Pumping procedure see section 3.
