3) Submerge other end of hose in clean glass jar partially
filled with clean brake fluid. Pump brake pedal several times, then
hold down. Open bleeder valve. Holding pedal down, close bleeder
valve. Release brake pedal.
4) Repeat procedure until brake fluid shows no signs of air
bubbles. When bleeding rear brakes, push lever of pressure regulator
in direction of rear axle.
5) After bleeding ABS vehicles, turn ignition on. Allow pump
to run until it shuts off. If pump runs longer than 2 minutes, allow
pump to cool for 10 minutes. On all vehicles, ensure master cylinder
reservoir is full.
ADJUSTMENTS
BRAKE PRESSURE REGULATOR
CAUTION: DO NOT adjust pressure regulator with brake pedal depressed.
1) Depress brake pedal once firmly. Release brake pedal
quickly, watching for regulator lever to move when pedal is released.
If regulator lever does not move when pedal is released, replace
regulator. If regulator lever moved, go to next step.
2) Ensure vehicle fuel tank is full, luggage compartment is
empty and a driver is in driver seat. Raise and support vehicle. Using
Pressure Gauges (US 1016), attach one gauge to right rear brake
cylinder or caliper. If vehicle is ABS-equipped, go to next step. If
vehicle is not ABS-equipped, go to step 4).
3) Using Distributor "T" (803 611 755) and an additional 8"
(203 mm) of brakeline, connect one gauge in front of pressure
regulator. Bleed pressure gauge and hoses through valve on gauges.
Lower vehicle. Bounce rear of vehicle several times. Go to step 5).
4) Attach Pressure Gauges (US 1016) to left front brake
caliper. Bleed pressure gauge and hoses through valve on gauges. Lower
vehicle. Bounce rear of vehicle several times.
5) Pump brake pedal several times. Press on brake pedal until
reading on front gauge shows pressure given for first reading in the
BRAKE PRESSURES table. Hold brake pressure to specification. Rear
gauge reading should be within specification given for first reading
in the BRAKE PRESSURES table.
6) Increase pressure on brake pedal until reading on front
gauge shows pressure given for second reading in the BRAKE PRESSURES
table. Hold brake pressure to specification. Rear gauge reading should
be within specification given for second reading in BRAKE PRESSURES
table. If pressures are within specification, brake pressure regulator
is functioning properly. If pressures are not within specification, go
to next step.
7) If pressure is too high, decrease spring pressure on
regulator. If pressure is too low, increase spring pressure on
regulator. If adjusting spring pressure on regulator does not bring
pressures within specification, replace pressure regulator. Disconnect
gauges, and bleed brakes.
