SERVICE BRAKE SYSTEM

SERVICE BRAKE PEDALS (2)

Directly connected to brake hydraulic cylinder.

Left pedal moves brake hydraulic cylinder left piston to operate left service brake.

Right pedal moves brake hydraulic cylinder right piston to operate right service brake.

Both pedals can be pushed at the same time for even braking for both rear wheels.

BRAKE HYDRAULIC CYLINDER

Supplied hydraulic fluid from transmission case sump by transmission oil pump through lubrication circuit.

Converts mechanical movement of service brake pedals to hydraulic pressure to operate service brakes.

Two circuits allow operation of left or right service brake alone, or both service brakes at the same time.

Equalizing valve adjusts for differences in pedal pressure for even braking when both pedals are pushed at the

same time.

RIGHT SERVICE BRAKE LINE

Routes hydraulic fluid from brake hydraulic cylinder to right rear axle housing.
