The vehicle is equipped with a vacuum-assisted

power braking system. For additional information,

refer to Section 206-07.
The braking system is a front-to-rear split hydraulic

system. For additional information, refer to Section

206-06.
The front brakes utilize a dual-piston brake caliper

and disc brake system. For additional information,

refer to Section 206-03.
The rear brakes utilize a single piston caliper and disc

brake system with the parking brake assembly located

inside the drum and hat-type brake disc. For

additional information, refer to Section 206-04.
The parking brake system is a shoe and drum system

that is located inside the drum and hat-type rear brake

discs. For additional information, refer to Section

206-05.
A 4-wheel anti-lock brake system (4WABS) is

standard. For additional information, refer to Section

206-09.

Load Proportioning Valve 1 Tonne Ute

The load proportioning valve regulates the rear brake

system hydraulic pressure and is located at the rear of

the vehicle.

The load proportioning piston is positioned by the use

of two springs. the static spring applies a constant

force on the piston while the sensing torsion spring

applies a variable force depending on the axle load.
When the vehicle is lightly loaded the sensing torsion

spring has its maximum effect. The total force on the

piston and plunger is greatest. This force postions the

load sensing piston to restrict the flow of fluid through

the outlet port to the rear brakes.
