If the master cylinder has been removed, the lines disconnected or the reservoir
allowed to run dry, the cylinder must be bled before the lines are bled. To
bleed the master cylinder:
| Fig. 1: Fill the reservoir with the correct type of brake
fluid
|
| Fig. 2: Depress the brake pedal . . .
|
- Check the level of the fluid in the reservoir. If necessary, fill with fluid.
- Disconnect the brake lines from the master cylinder. Plug the lines to keep
dirt from entering.
- Place a pan or rags under the cylinder.
- Have an assistant slowly depress the brake pedal and hold it down.
- Block off the outlet ports with your fingers. Be sure to wear gloves. Have
the assistant release the pedal. Make a tight seal with your fingers; do not
allow the cylinder to ingest air when the pedal is released.
