BLEEDING THE SYSTEM
The first requirement for safe, sure hydraulic braking is the use
of quality brake fluid. Use only DOT-3 or DOT-4 brake fluid from
a sealed container.
If pressure bleeding equipment is available, follow the manu-
facturer’s instruction in bleeding the system.
If system must be bled manually, proceed as follows: Fill
master cylinder with fluid. Install bleeder hose on top bleeder
of first caliper to be bled.
NOTE: always bleed brakes by using the top bleed screw
on the caliper.
Have loose end of hose submerged in brake fluid in glass
container to observe bubbling.
By loosening the top bleeder screw located on the caliper one
turn, the system is open to the atmosphere through the passage
drilled in the screw. Pump actuator with long steady strokes.
The bleeding operation is completed when bubbles no longer
rise to the surface of the fluid.
Be sure to close bleeder screw
securely.
Repeat bleeding operation at each caliper. During the bleed-
ing process, replenish the brake fluid, so the level does not fall
below the 1/2 full level in the master cylinder reservoir. After
bleeding is complete, make sure master cylinder reservoir is
filled and filler cap is securely in place.
After the bleeding operation has been completed, apply pressure
to the system and check the whole brake system for leaks.
