6.6.4. Repair of a support of a brake of a back wheel

Order of performance of repair work following:
1) preparation:
— disconnect an internal cable from the handle of the parking brake;
— remove a wheel;
— carefully clear a support;
2) merge brake fluid:
— remove a protective cap from the drain union, put on it a hose which second end lower in capacity for collecting brake fluid, and turning off, open the union;
— record a brake pedal in the pressed situation with the help of the holder. Collect the coming-out brake fluid in capacity.
3) remove a back support assembled:

Fig. 6.13. Removal of a support: 1 — a cable of the parking brake; 2 — a bolt of the directing finger;
3 — a support; 4 — a brake hose

Fig. 6.14. Details of a back support: 1 — a cover; 2 — the piston; 3 — an antisplash cuff;
4 — a sealing ring; 5 — the support case; 6 — the union

— disconnect a brake hose of 4 (fig. 6.13) from a support;
— turn out bolts 2 of the directing support fingers;
— remove a brake support 3 from the holder and take out brake shoes;
— disconnect a cable of 1 parking brake from a support, previously having delayed a rubber cover of a cable;
— merge the remains of brake fluid.
4) sort a support:
— take out the piston 2 with its cover 1, turning out it counterclockwise from a support;
— accurately take a sealing ring 4 of the cylinder so that not to damage an edge of flutes; turn out the drain union 6;
5) clear and examine a support:
— wash out elements alcohol;
— check existence of wear, damages, cracks and a rust. If necessary replace details;
— surely replace a sealing ring 4 and an antisplash cuff 3;
— especially carefully clear channels and flutes for a sealing ring and an antisplash cuff. In the presence in the cylinder рисок or scratches replace a support assembled. Remove small deposits of a rust with a fine-grained grinding skin;
6) collect a support:
— blow details compressed air;
— grease with brake fluid of a surface of a sleeve of the cylinder, piston and a new sealing ring;
— put a sealing ring in the cylinder, an antisplash cuff on the piston; the piston with an antisplash cuff in the cylinder;
— carefully press the piston into the cylinder before contact of a nut and the screw and turn clockwise;
— be convinced that the antisplash cuff 3 rose on the place.
— wrap the drain union 6;
— check a condition of a guide of a support and a brake disk;
— put brake shoes;
— mount a cable of the parking brake;
— establish a support on the holder and wrap two bolts 2 (see fig. 6.13) the moment of 33 N · m;
— connect a brake hose 4, using new consolidations. Tighten the moment 29 N · m. Make sure that the brake hose is not overwound;
— pump over the brake system and tighten the drain union the moment of 5 N · m;
— establish a wheel.
— press several times a brake pedal, check level in a tank of brake fluid and adjustment of the parking brake;
— check pressure in systems of brakes and couplings and if necessary, having convinced of lack of a leak, pump over;
— put a protective cover of the holder of the socket.
