Disc & Drum: Description
The hydraulic brake system uses a tandem master cylinder with a vacuum power assist servo. All other 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.
NOTE:
Since 4Runner and Pickup models share similar brake systems, the term Pickup will apply to all of these models unless specified otherwise.
