BRAKE BLEEDING / FLUID CHANGE
NOTE: When bleeding the brakes or replacing the
fluid always start with the furthest caliper from the
master cylinder. This procedure should be used to
change fluid or bleed brakes during regular
maintenance.
1. Clean master cylinder reservoir cover thoroughly and
remove the cover.
2. If changing fluid, remove old fluid from reservoir with
a Mity Vac™ pump or similar tool.
3. Add brake fluid to the indicated MAX level of reservoir.
4. Begin bleeding procedure with the caliper that is
farthest from the master cylinder. Install a box end
wrench on caliper bleeder screw. Attach a clean, clear
hose to fitting and place the other end in a clean
container. Be sure the hose fits tightly on fitting.
5. Have an assistant slowly pump foot pedal until
pressure builds and holds.
6. Hold brake pedal down to maintain pedal pressure,
and open bleeder screw. Close bleeder screw and
release pedal.
NOTE: Do not release foot pedal before bleeder
screw is tight or air may be drawn into master
cylinder.
7. Repeat procedure until clean fluid appears in bleeder
hose and all air has been purged. Add fluid as
necessary to maintain level in reservoir.
8. Tighten bleeder screw securely and remove bleeder
hose. Torque bleeder screw to specification.
9. Repeat steps 5 - 8 for the remaining calipers.
10. Add brake fluid to MAX level inside reservoir.
11. Install master cylinder reservoir cover.
Always wear safety glasses.
Brake fluid will damage finished surfaces.
Do not allow brake fluid to come in contact
with finished surfaces.
