Hydraulic Brake System Bleeding

Caution: Do not move the vehicle until a firm brake pedal is obtained. Air in the brake system can cause the loss of brakes with possible personal injury.

A bleeding operation is necessary in order to remove air from the hydraulic brake system whenever air is introduced into the brake system.
Bleed the hydraulic system at all four brakes if air has been introduced into the system through low fluid level or by disconnecting the brake pipes at the master cylinder. If a brake pipe is disconnected at one wheel, bleed only that wheel cylinder/caliper. If the pipes are disconnected at any fitting located between the master cylinder and brakes, bleed the brake system served by the disconnected pipe.

Observe the following steps in order to reduce the time required to bleed the hydraulic system:





^ Ensure that the master cylinder reservoir is filled with brake fluid.
^ Expel as much air as possible before installing the master cylinder on the vehicle.
