7.6.6. Replacement of brake shoes


Fig. 7-11. Brake mechanism of a forward wheel: 1 — the union for pumping of the drive of forward brakes; 2 — a connecting tube of working cylinders; 3 — a wire of a signaling device of wear of overlays of brake shoes; 4 — the piston of the wheel cylinder; 5 — a clamp of the wheel cylinder; 6 — an overlay of a brake shoe; 7 — a sealing ring; 8 — a dustproof cap; 9 — fingers of fastening of blocks; 10 — a bolt of fastening of a support to an arm; 11 — a rotary fist; 12 — an arm of fastening of a support; 13 — a support; 14 — the protection cover; 15 — the forelock; 16 — a clamping spring of a block; 17 — brake shoes; 18 — the wheel cylinder; 19 — a brake disk

Replace blocks new if thickness of slips decreased to 1,5 mm or the wire of a signaling device of wear of brake shoes became bare. For replacement of blocks separate shtekkerny connection of wires of signaling devices of wear of overlays of brake shoes, remove forelocks 15 (see fig. 7-11) and fingers 9 with springs, and then take out blocks 17 and springs 16.
Carefully, not to damage dustproof caps and not to allow slopping of liquid from a hydraulic actuator tank, drown pistons in cylinders. Put new blocks with new slips and establish into place fingers, springs and forelocks. Connect shtekkerny connection of wires of a signaling device of wear of overlays of brake shoes.
