BRAKES
3. Install brake shoe retracting springs and
link.
4. Install hydraulic brake hose as described in
Note 11.
5. Install brake drum and wheel assembly.
6. Bleed line to brake wheel cylinder that was
removed as explained in Note 9.
NOTE: Avoid handling friction surfaces of
drums and linings as much as possible.
7. Lower car.
9. Bleeding Brakes
Bleeding brakes may be made considerably
.easier through use of one of the pressure brake
bleeder tools available. This equipment consists
of a tank partially filled with brake fluid and
rubber hose that connects to the hydraulic cyl-
inder reservoir. Air pressure is developed in the
tank to force fluid into the brake system.
After bleeding brakes, check pedal travel as
described in Note 1, Step 7. Rebleed or adjust
brakes as necessary.
CAUTION: Do not spill brake fluid on car
finish or damage will result.
a. Bendix Brake Unit
1. Remove master cylinder reservoir filler
caps and fill both reservoirs with fluid.
2. Connect bleeder hose to front reservoir.
3. Install solid filler cap on rear reservoirs.
NOTE: A solid filler cap can be made by
welding the vent hole closed on any metal filler
cap.
4. Build up pressure in bleeder.
5. Attach drain hose to bleeder fitting on wheel
cylinder.
6. Back off fitting three quarters of a turn and
bleed brake fluid into a partially filled bottle of
clean brake fluid until bubbles stop, then close
fitting.
7. Repeat this operation for each wheel
cylinder.
b. Delco Moraine Unit
1. Connect bleeder hose to front master cyl-
inder reservoir.
2. Build up pressure in bleeder.
3. Attach drain hose to bleeder fitting on each
rear wheel cylinder in turn.
4. Back off rear brake bleeder fitting three
quarters of a turn and bleed brake fluid into a
partially filled bottle of clean brake fluid until
bubbles stop, then close fitting.
5. Connect bleeder hose to rear master cylin-
der reservoir and repeat procedure for front
wheel cylinders.
c. Alternate Method
If a pressure bleeder is not available, the fol-
lowing two-man procedure may be used for either
unit.
1. Fill both master cylinder reservoirs with
brake fluid. Keep reservoirs at least partially
filled at all times during bleeding operation.
2. Back off both master cylinder outlet pipe
nuts one turn and completely pump brake pedal
five times, catching fluid displaced from outlets
in a cloth or can. Discard this fluid and re-
tighten outlet pipe nuts.
3. Attach drain hose to fitting on wheel cylinder
and suspend loose end of hose into partially filled
bottle of clean brake fluid.
4. Apply pressure to brake pedal, back off
bleeder fitting one quarter turn, and depress
brake pedal. Close bleeder fitting before releasing
pressure on brake pedal. Repeat pedal applica-
tions until bubbles stop.
5. Bleed each wheel cylinder in turn, following
this same procedure.
