Brake Bleeding: Service and Repair
Hydraulic System Bleeding
General Information
The braking system can be bled manually or with pressure bleeding equipment. If bleeding manually, check fluid level frequently.
Brake fluid should never be reused. Before driving the vehicle, check brake operation to ensure a firm pedal has been obtained.
Brake fluid will damage electrical connections and painted surfaces. Use shop cloths, suitable containers, and fender covers to prevent brake
fluid from contacting these areas. Always seal and wipe off brake fluid containers to prevent spills.
Manual
The master cylinder has three brake pipe outlet ports which must be bled to ensure proper operation. Bleed one port at a time until all air is removed
before continuing to next port.
1. Fill master cylinder reservoir with DOT 3 brake fluid. Maintain full level during bleeding procedures.
2. If master cylinder is replaced or suspected to have air in the bore, bleed it before calipers.
a. Disconnect selected brake pipe connection port at master cylinder and allow brake fluid to flow from connector port, then reconnect pipe but
do not tighten.
b. Slowly apply brake pedal to allow air to bleed from loose fitting, then tighten fitting before releasing brake pedal.
c. Wait 15 seconds, then repeat sequence, including 15 second wait, until all air has been purged from bore.
d. After all air has been removed from selected port, repeat procedure for next port, and then final port.
3. There is no bleeder valve for the right rear brake. The rear brakes can only be bled through the bleeder valve located on the left rear brake. Bleed
wheels in the following sequence:
a. Left rear.
b. Right front.
c. Left front.
4. Attach clear hose to bleeder valve with opposite end of hose submerged into suitable, clean, transparent container partially filled with clean brake
fluid.
5. Slowly apply brake pedal one time and hold, loosen the bleeder valve to purge air from caliper, then tighten bleeder valve and release pedal.
6. Wait 15 seconds, then repeat sequence, including 15 second wait, until all air is purged from caliper.
7. Repeat steps 4 through 6 at each wheel until system is bled.
8. Check brake pedal for sponginess. Repeat bleeding procedure to correct this condition.
Pressure
Fig. 2 Bleeding Brakes
A diaphragm type pressure bleeder must be used. It must have a rubber diaphragm between the air supply and the brake fluid to prevent air, moisture, oil,
and other contaminants from entering the hydraulic system. Also, an adapter is needed to attach bleeder to master cylinder reservoir.
