Bleeding the Hydraulic Brake System

Air in the hydraulic brake system will cause a springy or spongy brake lever action. Bleeding is necessary to remove air from the system.

CAUTION

Brake fluid will damage decals, paint, and some plastics. Wipe up spills immediately.

1Remove brake master cylinder reservoir cover and gasket.

2Fill the master cylinder reservoir to between the MIN and MAX marks or 1/4-5/16(.6-.8 cm) below the lip of the reservoir opening. Reinstall the gasket and cover.

3Slip a rubber tube over the ball of the bleeder valve and direct the flow of fluid into an approved container.

4Squeeze brake lever a full stroke. Then unscrew bleeder valve 3/4 of a turn to release air.

5Close bleeder valve and release brake lever.

6Repeat steps 4 and 5 until fluid flows from the bleeder valve in a solid stream free of air bubbles.

WARNING

Do not overfill the master cylinder. Fluid expansion may cause brakes to lock, resulting in serious injury or death.

7After bleeding is complete, refill the reservoir to the proper level. See Replenishing Brake Fluid on page 126.

8Reinstall the gasket and cover.

During the bleeding procedure, keep the brake handle in as level a position as possible. The reservoir must be in this position to minimize the possibility of air entering the system through the reservoir vent.
