Abstract

PURPOSE: To prevent rusting to be caused by muddy water, by disposing an adjustment nut, which is in engagement with an adjustment bolt, between a clutch plate attached to the inner extremity of a piston and a stepped piston, which pistons are embraced witin a wheel cylinder.
CONSTITUTION: When a brake lining is worn out beyond a predetermined level, the relative spacing distance between the left-hand and right-hand pistons 41, 22 disposed within a wheel cylinder increases. Then, an adjustment bolt 20 non-reversibly threaded on the left-hand piston 41 causes an adjustment nut 18 reversibly threaded on the right-hand piston 22 to move away from a clutch plate 23. The movement of the adjustment nut 18 eventually exceeds the gap S and the adjustment nut 18 is brought into contact with the stepped piston 21. Subsequent movement of the adjustment bolt 20 causes the adjustment nut 18 to rotate, thereby restricting the return of the left-hand and right-hand pistons 41, 22, when the brake is released, and thus serving to adjust the braking gap. If a braking force is applied in such a degree that the drum would be deformed, the stepped piston 21 moves while compressing a bellville spring 5, thereby to prevent any excessive adjustment.
