Disc & Drum: Description

Hydraulic brake system uses tandem master cylinder with vacuum operated power assist servo. GLI and GTI models have 4-wheel disc brake systems. All other models have front disc brakes and self-adjusting rear drum brakes. All models are equipped with cable-actuated parking brake, which applies rear brakes.

All models use pressure regulator between front and rear brake circuits to avoid rear wheel lock-up during hard braking. Pressure regulator on Vanagon models is nonadjustable proportioning type which is controlled by changes in operating angle of regulator.

On all other models, adjustable pressure regulators are used. Adjustable regulators vary braking pressures in direct proportion to tension placed upon operating spring. Operating spring is attached to control lever on regulator and bracket on axle. If vehicle weight transfer increases distance between lever and axle, tension on spring increases and regulator applies higher pressures to rear brakes.
