Figure 287. Removing the rear brake disc: 1 — bolt, 105–110 N·m; 2 — caliper bracket; 3 - brake disc; 4 — bolt, 20 Nm
Figure 287 shows the rear brake disc mount. To remove it, you must first remove the caliper and caliper bracket, as described earlier. Removal of the rear brake cylinder must be carried out in the following order:
- unscrew the caliper mounting bolts and remove it. Tie it with wire to the rear axle so that it does not hang on the brake hose. When assembling, ensure that the brake hose is not twisted or rubs against other parts;
- unscrew the brake disc mounting bolt. When unscrewing, raise the parking brake lever, and lower it again when finished;
Figure 288. Adjusting the parking brake drive mechanism
- before removing the disc, the parking brake pads must be released. To do this, insert a screwdriver as shown in the picture 288, through the hole in the hub and remove the brake shoe installation gear. This is necessary so that the pads move away from the drum and do not interfere with removal. Knock off the disc with a rubber or plastic hammer;
- before reinstalling the disk, please read the following section. Tighten the disc mounting bolt to 20 Nm, the caliper mounting bolts to 105–115 Nm. After tightening, check again that the brake hose is positioned properly.
The parking brake drive mechanism must be adjusted as follows:
- insert a screwdriver (figure 288) and turn the parking brake shoe setting mechanism;
- turn the gear until the disk stops rotating;
- from this position, move the gear back 5 teeth.
