Abstract
PURPOSE: To simplify initial adjustment of the drum brake and to keep its brake clearance always at a proper value, by providing a wheel cylinder means of the type in which a pair of pistons are fitted in a cylinder.
CONSTITUTION: In operation of brake, an adjusting nut 6 and an adjusting bolt 5 are moved to the right together with piston 44 and only piston 4 is moved to the left, until a brake shoe 22 comes into contact with the drum and the brake clearance becomes zero. On the contrary, if the brake clearance becomes larger than a predetermined value, the nut 6 and bolt 5 are moved to the left together with the piston 4 while deflecting a spring 9. On the other hand, if hydraulic pressure becomes higher than a predetermined level after the shoe 22 has come into contact with the drum, engagement of the bolt 5 and over-adjustment compensating piston 12 is removed and the bolt 5 is turned to the right through a distance corresponding to that through which it has moved to the left together with the piston 4. Accordingly, over-adjustment due to deformation of the drum can be compensated.
