PARKING BRAKE (REAR DISC BRAKES)
Parking Brake
A: OPERATION
1. SETTING
When the parking brake lever is pulled, the shoe actuating lever to which the end of the parking
brake cable is connected turns the strut in direction "F" around point "P".
The strut then presses the brake shoes A and B against the drum. These brake shoes utilize afloat-
ing design and are movably supported by hold-down pins. The force applied to brake shoe A and
the reaction force "F" applied to the brake shoe B via point "P" press them against the brake drum.
