Drum-type brake mechanisms - the general information

Typical design of the drum-type brake mechanism

1 — the Spring of fastening of a boot to the regulator lever
2 — the Top coupling spring
3 — regulator Assembly
4 — the Wheel cylinder
5 — the regulator Lever

6 — Directing springs
7 — Anchor fingers of directing springs
8 — the Bottom coupling spring
9 — Brake boots
10 — the Executive lever of a drive of the parking brake



The typical design of the drum-type brake mechanism is presented on an illustration.

Two boots equipped by frictional slips are established on motionlessly fixed brake board. Boots are concluded in a drum rotating together with wheel assembly. Boots are fixed on the seats by means of springs that provides with it a certain extent of moving with clip possibility to a working surface of a drum. The clip of boots to a drum is carried out at the expense of the effort developed by pistons of the wheel cylinder at squeezing by the driver of a pedal of a foot brake. Nestling a surface of frictional slips on drum walls, boots interfere with its rotation therefore process of braking of a vehicle is carried out. At release of pressure in a hydraulic path boots, at the expense of the effort developed by coupling springs, come back to a starting position, wringing out pistons and releasing a drum.

Modern drum-type brake mechanisms are equipped with the self-regulators providing compensation of wear of frictional slips. Regulators work automatically when braking the car moving by a backing.

 On some models self-regulators work at each braking of the car.
