Grand AM V6-3100 3.1L MFI VIN M (1994)
5. Prime hydraulic modulator as follows:
A. Attach a clear bleeder hose to the rearward bleeder valve and submerge opposite hose end in clean container partially filled with clean brake
fluid.
B. Slowly open rearward bleeder valve 1/2 to 3/4 turns.
C. Depress brake pedal and hold until fluid begins to flow.
D. Close valve and release brake pedal.
E. Repeat Step 5B through 5D until no air bubbles are present.
F. Relocate the bleeder hose to the forward hydraulic modulator bleeder valve and repeat Steps 5A through 5E.
Important: Once fluid is seen to flow from both modulator bleeder valves, the hydraulic modulator/master cylinder assembly is sufficiently full of fluid.
However, it may not be completely purged of air. At this point move to the wheel brakes and bleed them. This ensures that the lowest points in the
system are completely free of air and then the hydraulic modulator/master cylinder assembly can be purged of any remaining air.
6. Remove fluid reservoir cover.
7. Inspect fluid level in reservoir and fill to the correct level if necessary.
8. Install fluid reservoir cover.
9. Raise vehicle and suitably support.
Important: Bleed sequence:
Right rear.
Left rear.
Right front.
Left front.
10. Proceed as follows to bleed wheel brakes in sequence shown above.
A. Attach a clear bleeder hose to the bleeder valve at each wheel and submerge opposite hose and in a clean container partially filled with clean
brake fluid.
B. Open bleeder valve.
C. Slowly depress brake pedal.
D. Close valve and slowly release brake pedal.
E. Wait 5 seconds.
F. Repeat Steps 10B through 1OE until the brake pedal feels firm at half travel and no air bubbles are observed in the bleeder hose.
Note: To assist in freeing entrapped air, tap lightly on caliper with a rubber mallet.
11. Repeat Step 10 on left rear wheel brake.
12. Repeat Step 10 on right front wheel brake
13. Repeat Step 10 on left front wheel brake.
14. Lower vehicle.
15. Remove fluid reservoir cover.
16. Inspect fluid level in reservoir and fill to the correct level if necessary.
