Jeep Grand Cherokee WK. Manual - part 95
STANDARD PROCEDURE
MANUAL BLEEDING
Use Mopar brake fluid, or an equivalent quality fluid meeting SAE J1703-F and DOT 3 standards only. Use fresh,
clean fluid from a sealed container at all times.
Do not pump the brake pedal at any time while bleeding. Air in the system will be compressed into small bubbles
that are distributed throughout the hydraulic system. This will make additional bleeding operations necessary.
Do not allow the master cylinder to run out of fluid during bleed operations. An empty cylinder will allow additional
air to be drawn into the system. Check the cylinder fluid level frequently and add fluid as needed.
Bleed only one brake component at a time in the following sequence:
1. Fill the master cylinder reservoir with brake fluid.
2. If calipers are overhauled, open all caliper bleed screws. Then close each bleed screw as fluid starts to drip from
it. Top off master cylinder reservoir once more before proceeding.
3. Attach one end of bleed hose to bleed screw and insert opposite end in glass container partially filled with brake
fluid. Be sure end of bleed hose is immersed in fluid.
4. Open up bleeder, then have a helper press down
the brake pedal. Once the pedal is down close the
bleeder. Repeat bleeding until fluid stream is clear
and free of bubbles. Then move to the next wheel.
PRESSURE BLEEDING
Use Mopar brake fluid, or an equivalent quality fluid
meeting SAE J1703-F and DOT 3 standards only. Use
fresh, clean fluid from a sealed container at all times.
Do not pump the brake pedal at any time while bleed-
ing. Air in the system will be compressed into small
bubbles that are distributed throughout the hydraulic
system. This will make additional bleeding operations
necessary.
Do not allow the master cylinder to run out of fluid
during bleed operations. An empty cylinder will allow
additional air to be drawn into the system. Check the
cylinder fluid level frequently and add fluid as needed.
Bleed only one brake component at a time in the fol-
lowing sequence:
Follow the manufacturers instructions carefully when using pressure equipment. Do not exceed the tank manufac-
turers pressure recommendations. Generally, a tank pressure of 51-67 kPa (15-20 psi) is sufficient for bleeding.
Fill the bleeder tank with recommended fluid and purge air from the tank lines before bleeding.
Do not pressure bleed without a proper master cylinder adapter. The wrong adapter can lead to leakage, or drawing
air back into the system. Use adapter provided with the equipment or Adapter 6921.
