Fig. 8 Plastic Reservoir Bleeder Adapter Installation:

Fig. 9 Cast Iron Reservoir Bleeder Adapter Installation:

A diaphragm type pressure bleeder must be used. It must have a rubber diaphragm between the air supply and the brake fluid to prevent air, moisture, oil, and other contaminants from entering the hydraulic system. Also, adapters are needed depending on the type of master cylinder reservoir used on the
vehicle:
Brake Bleeder Adapter (Plastic Reservoir) tool No. J 29567, or equivalent, Fig.8.
Brake Bleeder Adapter (Cast Iron Reservoir) tool No. J 23518-01, or equivalent, Fig. 9.

Fig. 10 Combination Valve Bleeding Tool Installation:

1. Fill the pressure tank at least 2/3 full of brake fluid. Bleeder must be bled each time fluid is added.
2. Charge pressure bleeder to 20-25 psi.
3. Use tool No. J 39177, or equivalent, to depress and hold valve stem on combination valve, Fig. 10.
4. Install master cylinder adapter tool required for type of reservoir, then install bleeder hose to adapter
5. Bleed each wheel in the following sequence:
a. Right rear.
b. Left rear.
c. Right front.
d. Left front.
6. Open bleeder tank valve.
7. Attach a hose to caliper bleeder valve and immerse the opposite end of the hose into a suitable, clean, container, partially filled with clean brake fluid.
8. Open bleeder valve at least 3/4 turn and allow fluid to flow until no air is seen in fluid, then close valve.
9. Repeat procedure at each wheel.
10. Check brakes for "sponginess. Repeat bleeding procedure if necessary.
11. Remove pressure bleeder, adaptors, and tools, then fill reservoir to proper level.
