E. Bleeding Hydraulic Brakes
If air enters the hydraulic brake system, the brake pedal action wil I fee I soft and
"spongy" when brakes are applied and braking may be erratic. Air will enter the
system if the master cylinder reservoir is allowed to become empty, or if the system
is opened for any reason. A leaking condition may also allow air to enter. To
remedy the condition the system must be "bled" to expel the air. The system may
be bled manually or with pressure bleeding equipment.
(1) Manual method
This bleeding method can best be accomplished by two mechanics; one to operate
the bleeder valves, and one to operate the brake pedal and keep the master
cylinder reservoir filled.
(a) Raise the vehicle so that the bleeder valves are easily accessible.
(b) Remove master cylinder access cover from floorboard (see 2-2, Fig. 17).
