Pressure
CAUTIONS:^ Do not perform bleeding operation while any brake drum is removed or with a caliper removed from the disc.
^ Pressure bleeding equipment must be of the diaphragm type. That is, 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.
1. Clean all dirt from the top of the master cylinder and remove the cylinder cover and rubber diaphragm.
Figure 5-3 Installing Brake Bleeder J-23518:
2. Install Brake Bleeder Adapter J-23518 on master cylinder.
3. Make sure pressure tank is at least 1/3 full of Supreme # 11 brake fluid or its equivalent.
NOTE: The bleeder ball must be re-bled each time fluid is added.
4. Charge the bleeder ball to 20-25 PSI (138-172 kPa).
5. When ready to begin bleeding, connect hose from bleeder equipment to bleeder adapter and open release valve on bleeder equipment.
6. Bleed the brakes in the following sequence:
a. Right rear brake.
b. Left rear brake.
c. Right front brake.
d. Left front brake.
Fig. 20 Bleeding Brakes:
7. With the proper size wrench over the bleeder valves, attach bleeder tube. The discharge end must hang submerged in a clean container partially filled with brake fluid.
8. Open bleeder valve at least 3/4 of a turn and allow fluid to flow until no air is seen in the fluid.
9. Close bleeder valve; be sure it seals.
10. Repeat Steps 6 through 8 on the remaining bleeder valves.
11. Check the pedal for "sponginess" and repeat the entire procedure if necessary.
12. Dispose of all removed brake fluid.
13. Disconnect bleeder equipment from brake bleeder adapter.
NOTE: The master cylinder is tilted slightly upward. When removing the bleeder adapter, place a clean dry cloth behind and below the cylinder to absorb any fluid spillage as the cover is removed.
14. Remove bleeder adapter. Wipe all areas dry if fluid was spilled during adapter removal.
15. Fill master cylinder reservoir(s) to the proper level and install master cylinder diaphragm and cover.
