Pressure Bleeding

REQUIRED TOOLS:
^ J 29532 Diaphragm Type Brake Pressure Bleeder (or equivalent)
^ J 35589 Pressure Bleeder Adapter Cap (or equivalent)
^ J 21472Brake Bleeder Wrench (or equivalent)

NOTE: Pressure bleeding equipment must be of the diaphragm type. 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.


CAUTION: Use only Delco Supreme II Brake Fluid (GM P/N 1052535) or an equivalent DOT-3 motor vehicle brake fluid.





1. Install Pressure Bleeder Adapter Cap to the master cylinder.
2. Charge Brake Pressure Bleeder to 140-172 kPa (20-25 psi).
3. Connect line to Pressure Bleeder Adapter Cap and open line valve.
4. Raise vehicle and suitably support.
5. If it is necessary to bleed all of the calipers/cylinders, the following sequence should be followed:
- Right rear
- Left rear
- Right front
- Left front
6. Place a proper size box end wrench or bleeder wrench over the caliper/cylinder bleeder valve.
7. Attach a clear tube over the bleeder screw. Submerge the other end of the tube in a clear container partially filled with clean brake fluid.
8. Open the bleeder screw at least 3/4 of a turn and allow flow to continue until no air is seen in the fluid.
9. Close the bleeder screw. Tighten Rear bleeder screws to 7 Nm (62 inch lbs.) and Front bleeder screws to 13 Nm (115 inch lbs.)
10. Repeat Steps 6 through 9 until all calipers/cylinders have been bled.
11. Lower vehicle.
12. Check the brake pedal for "sponginess." Repeat entire bleeding procedure to correct either of these two conditions.
13. Disconnect pressure bleeder and remove adapter cap from master cylinder.
14. Fill the master cylinder to the proper level.
