Pressure Bleeding

Before bleeding the brakes, the front and rear displacement cylinder pistons must be returned to the top most position. Using a TECH 1 or equivalent scan tool, enter manual control function and ``Apply'' the front and rear motors. Ensure enable relay is on.
Use only Dot 3 brake fluid from a clean and sealed container. Do not use Dot 5 brake fluid.

1. Remove master cylinder cover, ensure reservoir is properly filled.
2. Connect bleeder adapter tool J 35589 or equivalent to master cylinder reservoir.
3. Connect bleeder adapter to pressure bleeding equipment.
4. Connect a clear plastic bleeder hose to modulator assembly rearward bleeder valve, submerge other end of hose into clean container partially filled with brake fluid.
5. Adjust pressure bleeding equipment to 5-10 psi, then wait for approximately 30 seconds to insure there is no leakage.
6. Adjust pressure bleed equipment to 30-35 psi.
7. To bleed ABS hydraulic modulator and master cylinder, proceed as follows:
a. Slowly open rearward bleeder valve and allow fluid to flow until no air is seen in fluid, then torque valve to 65 inch lbs..
b. Attach bleeder hose to modulator assembly forward bleeder hose.
c. Slowly open forward bleeder valve and allow fluid to flow until no air is seen in fluid, then torque valve to 65 inch lbs..
8. To bleed brake pipe to modulator assembly connections, proceed as follows:
a. Place a shop cloth between brake pipe connections and the top of the motor pack assembly.
b. Loosen forward most brake pipe nut and check for air escaping in fluid.
c. When air flow ceases, torque brake pipe nut to 24 ft. lbs..
d. Repeat steps b and c for remaining three brake pipe connections, moving from front to rear.
9. To bleed wheel brakes, proceed as follows:
a. Raise and support vehicle.
b. Attach bleeder hose to bleeder valve of right rear wheel, submerge other end of hose into clean container partially filled with brake fluid.
c. Loosen bleeder valve and allow fluid to flow, close valve when fluid begins to flow without any air bubbles.
d. Repeat steps b and c, first for left rear wheel, then the right front caliper, then the left front caliper.
10. Road test vehicle, to verify brake performance.
