D) Brake Bleeding

1) After the installation of the Prop Block is complete, it will be necessary to bleed the brake

system.

2) If the master cylinder is new or went dry at any time during the installation, begin by bench

bleeding the master cylinder.

3) Continue the bleeding process by gravity bleeding the caliper or wheel cylinder at each wheel

until no air bubbles are seen in the escaping brake fluid. Start with the wheel farthest from the

master cylinder and work your way closer bleeding each wheel. Never let the master cylinder go

dry at any time during this process.

4) With all the bleeding complete, a firm consistent pedal feel should be achieved. If the vehicle

already had a functioning brake system prior to the installation of the Prop Block, there should be

no significant change in the pedal feel.

5) With all bleeding complete, check all the fittings for leaks and tighten as necessary.

E) Proportioning Valve Adjustment

1) The proportioning valve in the Prop Block will be used to adjust the rear brake pressure of the

vehicle. The objective is to balance the pressure of the rear brakes to the front so that under hard

braking, the rear brakes do not lock up before the fronts.

2) Start with the valve in the full increase position by turning the knob all the way out in a clockwise

rotation.

3) Find a safe open area such as parking lot and make several hard stops from 30 M.P.H. observing

the function of the rear brakes. If the rear brakes lock up well before the front, begin to decrease

the rear brake pressure by turning the knob in a counter clockwise rotation. Continue these

adjustments until the proper balance is found.

4) When you have found the proper adjustment for your vehicle try the test again at 50 M.P.H. and

make any further adjustments as necessary.

DO NOT DRIVE IN TRAFFIC UNTIL THE BRAKES SAFELY STOP THE CAR IN A SAFE

DISTANCE WITHOUT A SPONGY PEDAL FEEL!

BRAKING TESTS SHOULD ALWAYS BE DONE IN A SAFE OPEN AREA!

NOW ENJOY TRUE PERFORMANCE BRAKING!
