Bleeding Anti-Lock Brake Systems
Always refer to the vehicle’s owner manual or the appropriate service manual for manufacturer’s brake
bleeding procedure. The front brakes on most anti-lock brake systems may be bled in the conventional
manner. Most hydraulic pump/pressure accumulator units are fitted with a bleeder valve, which must be
bled when the system has lost fluid or is being replaced. Some vehicles require that the system be
pressurized when the rear brakes are bled. Acura, Ford and General Motors require a bleeding
procedure, which uses specialized equipment.
Bench Bleeding System
Whenever a master cylinder has been removed from a vehicle or a new one is being installed, the
master cylinder must be bench bled. Failure to bench bleed is the main reason for unsuccessful master
cylinder replacement. Bench bleeding greatly decreases the chance that any air will be caught in the
cylinder upon reinstallation. Most manufacturers include a bench bleeding kit with new or remanufactured
master cylinders. If this kit was not included with the replacement part to be installed, consult with your
retailer prior to installing the new or rebuilt master cylinder on the vehicle.
