Caprice Wagon V8-305 5.0L (1986)
Installing Bleeding Adapter J-29567
1. Install bleeding adapter J-29567 to the master cylinder.
CAUTION:It is very important that the correct master cylinder bleeder adapter be used to avoid possible damage to the master cylinder reservoir.
2. Make sure the pressure tank is at least 1/3 full of Delco Supreme #11 brake fluid or its equivalent DOT 3.
NOTE: The bleeder ball must be re-bled each time fluid is added.
3. Charge the bleeder ball to between 20 and 25 PSI (140 and 173 kPa).
4. When ready to begin bleeding, connect hose to master cylinder bleeding adapter and open the tank valve.
5. The plastic reservoir type bleeder adapter is equipped with a special bleed-off valve. The valve must be depressed until several drops of fluid
appear before bleeding the brake system.
6. Disc brake cars require a manual override of the front brake metering or combination valve to permit flow to the front wheels. Therefore, it will be
necessary to hold the valve stem open manually with tool J-23709 when pressure bleeding.
7. Bleed the brakes in the following sequence:
a. Right rear
b. Left Rear
c. Right front
d. Left front
8. With the proper size wrench over the bleeder valves, attach bleeder tubes. The discharge end must hang submerged in a clean container partially
filled with brake fluid.
9. Open the bleeder valves at least 3/4 turn and allow flow to continue until no air is seen in the fluid.
10. Close the bleed valves. Be sure they seal.
11. Repeat steps 7 through 10 until all calipers have been bled.
12. Check the pedal feel for "sponginess" and repeat the entire procedure if necessary.
13. Dispose of all removed brake fluid.
14. Remove the metering valve actuator (J-23709) from the combination valve and tighten the mounting bolt.
