Brake Valve and Service Brake Pedal
The service brake valve is secured at the base of the
steering column support inside the dash, concealed by
the lower dash panel.
The service brakes are part of the axles (the park brake
is part of the front axle only). Refer to Section 5, “Axles,
Drive Shafts, Wheels, Tires and Brakes,” for further
information.
a. Brake Valve Removal
1. Park the vehicle on a firm level surface, fully retract
all hydraulic cylinders and ground attachment, (if
any). Place the travel selector lever in the (N)
NEUTRAL DETENT position, engage the park brake
switch and shut the engine off.
2. Unlatch and open the engine cover. Allow the
hydraulic fluid to cool.
3. Pump the brake several times to relieve all of the
stored pressure in the accumulator system.
4. Remove the lower dash panel (1).
5. Label, disconnect and plug the six hoses (2)
attached to the service brake valve (3) and cap the
fittings on the service brake valve.
WARNING:
Wait for the hydraulic fluid
to cool before servicing any hydraulic component.
Hot hydraulic oil can cause severe burns.
WARNING:
Hydraulic fluid leaking under
pressure can penetrate the skin, cause infection,
gangrene, and death or serious personal
injury. If injured, see a doctor immediately.
Relieve all pressure before disconnecting any
component, part, line or hose. Slowly loosen
parts and allow release of residual pressure
before removing any parts or component.
