Introduction:
Unlike drum brakes, disc brakes have limited self-energizing action making it necessary to apply greater hydraulic pressure to obtain sufficient braking force. This is accomplished by increasing the size of caliper piston. The simple design facilitates easy maintenance and pad replacement.
Components of disc brakes:
A disc brake assembly consists of a:
Operation:
The friction surface is constantly exposed to the air, ensuring good heat dissipation, minimizing brake fade. It also allows for self-cleaning as dust and water are thrown off, reducing friction differences.
