HYDRAULIC BRAKE BOOSTER

COMPONENTS:

REMOVAL

NOTICE:
^ Before starting the work, make sure that the ignition switch is OFF and depress the brake pedal more than 40 times.
^ As high pressure is applied to the No. 1 brake actuator tube, never deform it.
^ Until the work is completed, do not turn the ignition switch ON.

HINT: When a pressure in power supply system is released, reaction force becomes light and stroke becomes longer.
