Repair Sharan/Sharan Volkswagen>> Brake system>> Brakes of back wheels>> Dismantling and assembly of the brake mechanism of a back wheel

Fig. 324. Details of the brake mechanism of a back wheel: 1 — a bolt of fastening of a wheel, 140 N · m; 2 — a bolt, 10 N · m; 3 — a brake disk; 4 — a bracket (directing blocks); 5 — a bolt, 110 N · m; 6 — a rubber cuff; 7 — a directing finger; 8 — a bolt, 35 N · m; 9 — the brake cylinder assembled with a support; 10 — brake shoes





The design of the brake mechanism of a back wheel is shown on (fig. 324) .
Dismantling of the brake mechanism carry out in the following order:
- put a back part of the car on a support and remove back wheels;
- remove the car from the parking brake. Disconnect a cable of the parking brake from a brake support;
- remove brake shoes;
- if it is necessary, remove a brake hose from the wheel cylinder;
- clamp the cylinder assembled with a support in a vice. Turn on the holder of a cable of the parking brake;
- by means of a special key of VW3272 turn out the piston from the brake cylinder;

Fig. 325. Removal of a sealing ring of the brake cylinder





- carefully screw-driver (fig. 325) take a sealing ring from the case of the brake cylinder. Do not damage thus a cylinder opening;
- carefully clear and check a condition of all details of the brake mechanism. If the cylinder and the piston are in a good condition, use a repair kit at assembly. The sealing ring of the cylinder and a dustproof ring to replace new is recommended. Surely track, that the repair kit corresponded to year of release.
Assembly of the brake mechanism of a back wheel carry out as it should be, the return to dismantling, thus:
- establish a new sealing ring in a cylinder flute, previously having greased it with brake liquid;
- put graphite greasing or Ditor greasing on a piston surface;
- put on a dustproof ring an external working edge the piston and insert the piston into a cylinder opening;

Fig. 326. Installation of a dustproof ring in a flute of the brake cylinder





- by means of a screw-driver carefully press an internal working edge of a dustproof ring into a cylinder flute (fig. 326) ;
- by means of a special key of VW3272 or a steel strip, screw the piston in the brake cylinder. During a vvertyvaniye evenly press on the piston. Thus the external working edge of a dustproof ring will enter into a piston flute as soon as it will appear opposite to it;
- put on the union for pumping of a drive of a brake greasing and wrap it;
- remove air from the brake cylinder. For what put on the union for pumping a hose, and its end put on on the filled brake liquid a syringe. Fill the cylinder with brake liquid until it will not start to leave through connection of a brake hose;
- after assembly and installation of the brake mechanism restore liquid level in a tank and pump over hydraulic actuator system.
