Disc & Drum: Description

The hydraulic brake system uses a tandem master cylinder with a vacuum power assist servo. All Three models are equipped with front disc and rear drum brakes.

A load sensing proportioning valve is used on some models to regulate brake pressure between the front and rear circuits. The rear brakes on all models are self-adjusting.

The parking brake lever mechanically activates the rear brakes. On models with rear drum brakes, a cable applies the rear shoes.
