Assembly

Insert the handle into the vertical sleeve behind the

gauge and tighten the set screw.

Filling And Charging The Bleeder

Release the air from the brake bleeder by depress-

ing the inflator valve. Then remove the valve core.

Remove the hose assembly from the fill hole on top

of the brake bleeder by loosening the wing nut and turn-
ing the lock plate 90˚. Use a clean blunt instrument to
gently push the diaphragm to the bottom of the bleeder
tank.

Insert a plastic funnel into the fill hole and add brake

fluid. The funnel will catch the overflow which can be
removed with the suction syringe.

Remove the funnel and replace the hose assembly

into the fill hole. Position the lock plate under the lock
tabs and tighten the wing nut.

Replace the valve core and tighten. Inflate to 15 PSI.

Insert the fill nozzle into the hose coupler, open the

shutoff valve and bleed the brake fluid into a cup until the
flow is free of bubbles. Add air to bring the bleeder’s
pressure back up to 15 P.S.I.

CAUTION: FOR SAFE OPERATION DO NOT

INFLATE TO MORE THAN 15 P.S.I.

Bleeding The Brakes

1. Pressurize the brake bleeder to not more than

15 P.S.I. Bleeding at this low pressure should not
cause the metering valve to close.

Use fender covers to protect paint from any acci-

dental brake fluid spills. If brake fluid is dripped on a
painted surface, immediately flush the area with water.

DO NOT try to wipe the brake fluid from the paint!

Remove the master cylinder cover. Refold the rub-

ber cover gasket if necessary.

Carefully wipe any grit from the upper perimeter of

the master cylinder reservoir.

Install the appropriate bleeder adapter on the mas-

ter cylinder. DO NOT pinch any brake lines or electrical
wires with the hold-down chains.

CAUTION:

Plastic

reservoirs may break if the adapter’s chains are over-
tightened. The chains should only be tight enough to seal
the adapter on the master cylinder.

Connect the bleeder’s quick coupler to the adapter.
