DESCRIPTION & OPERATION
Disc/drum brake system is hydraulically operated using a master cylinder with a single reservoir and 2 outlets.
A vacuum assist power brake booster is used. Proportioning valves are used to control anti-skid braking action.
Mechanical parking brake system isself-adjusting.
Disc brake pads have built-in wear indicator warning sensors. When brake pad lining is low, sensor will rub
against rotor, causing a very notable squealing sound.

BLEEDING BRAKE SYSTEM
