Bleeding the Brake System


The bleeding procedure is necessary to remove air whenever it is introduced into the hydraulic brake system.

Bleed the hydraulic system at all four brakes if air has been introduced by a low fluid condition or disconnecting the brake pipes at the master cylinder or the Brake Pressure Modulator (BPM) valve. If a brake pipe is disconnected at any wheel only that caliper need be bled. If pipes are disconnected at any fitting located between the master cylinder and the brakes then the brake system served by the disconnected pipe must be bled.
