REPLACEMENT
Note
l A common reservoir is used for the clutch and brake
system fluids.
l The fIuid in the reservoir must be maintained at 314
tevet or higher during replacement.
Caution
l Be careful not to spill the fluid on a painted surface.
If this should happen, wash it off immediately.
l Do not mix different brands of fluid.
l Do not reuse the clutch fluid that was drained.
1. Drain the brake fluid from the master cylinder by pumping
it through a wheel cylinder bleed screw.
2. Remove the bleeder cap from the clutch release cylinder
and attach a vinyl hose to the bleeder plug.
93GOHX-77 3
3. Place the other end of the vinyl hose in a clear container.
4. Fill the reservoir with new fluid to the MAX mark.
5. Slowly pump the clutch pedal several times.
6. With the clutch pedal depressed, loosen the bleeder screw
with the SST to let the fluid escape. Close the bleeder screw
with the SST.
7. Repeat Steps 4 and 5 until only clean fluid is seen.
8. Tighten the bleeder screw.
Tightening torque:
5.9-8.8 Nom (60-90 cm-kg, 52-78 in-lb)
9. Add fluid to the MAX mark.
IO. Slowly pump the clutch pedal several times.
Verify that there is no fluid leakage.
11.
Check operation of the clutch system.
12. Bleed and check operation of the brake system.
