Checking the wheel cylinder for leaks
1 – wheel cylinder; 2 – shoulder blade; 3 – protective cap
Examination
1. When removing the brake drum, it is recommended to periodically check the tightness of the wheel cylinder 1 (see figure Checking the tightness of the wheel cylinder).
2. To do this, using a wooden or plastic spatula 2, carefully, so as not to damage, press back the edges of the protective caps 3.
3. If traces of brake fluid are found inside the caps, the wheel cylinder must be replaced.
Replacement
Please note: The wheel brake cylinder cannot be repaired. If it malfunctions, it must be replaced as a complete unit.
1. Remove the brake pads (see subsection 9.7.1).
2. Loosen the mounting nut and disconnect the brake pipe 10 (see figure Installing the rear wheel drum brake mechanism) from the wheel cylinder. Plug the opening of the tube, for example with an air release valve cap.
3. Unscrew two bolts 12 (see figure Rear wheel drum brake mechanism parts) fasteners and remove wheel cylinder 11 from brake shield 14.
4. Install the wheel cylinder in reverse order. Bleed the brake system (see subsection 9.9.6).
