1 l-26. SERVICE BRAKE SYSTEM OPERATION
The service brake system is identical for both models covered in this manual. It is an inboard-mounted, four-
wheel, disc brake, hydraulically-assisted system. Major components of the braking system are:
BRAKE LINEAGE - Directs brake pedal pressure to hydro-booster.
HYDRO-BOOSTER - Converts hydraulic power from the steering pump to mechanical power to
the master cylinder, providing power assist during braking.
MASTER CYLINDEIURESERVOIR - Stores brake fluid, and converts mechanical pedal pressure
to hydraulic pressure.
PROPORTIONING VALVE - Provides balanced front-to-rear braking and activates brake
warning lamp in case of brake system malfunction.
ACCUMIJLATOR - Stores hydraulic pressure for additional power-assisted braking in case of loss
of pressure in steering system.
BRARE PEDAL - Provides operator control for stopping vehicle.
BRAKE PRESSURE LIMITER - Limits front brake line pressure to prevent brake lockup.
