BRAKE SYSTEM 495 BRAKES The front drum brake has two brake shoes, a piston, an auto adjuster mechanism, an emergency brake mechanism and springs. When the brake pedal is depressed, the piston pushes the brake shoes against the drum. The drum brakes are self-energizing. As the brake shoes contact the drum, there is a kind of wedging action, which has the effect of pressing the shoes into the drum with more force in leading direction. The shoes get pulled back from the drum when the brakes are released. The return springs between the leading and trailing shoe helps to hold the brake shoes in place and causes them to return to their original position. 6.2 COMPONENT DESCRIPTION OF BRAKE SYSTEM FRONTDRUMBRAKES 1 Brake shoe 2 Wheel cylinder 3 Auto adjuster mechanism 4 Brake shoe hold down assy. 2 3 4 1
