Accelerator & Brake System
Always turn keyswitch to OFF and remove. Turn
direction knob to Neutral, block tires and disconnect
the battery negative (-) cable before performing any
vehicle service to avoid accidental startup of vehicle
and possible injury.
ACCELERATOR PEDAL
Accelerator
pedal
maintenance
consists of
periodic inspection. No lubrication or adjustment is
necessary.
The accelerator pedal works in conjunction with the linear
accelerator and the Sevcon controller to adjust and control
vehicle direction and speed.
All adjustments are made using the handheld Calibrator. See
Section 4-Troubleshooting.
MECHANICAL BRAKE SYSTEM GENERAL
The mechanical braking system consists of two rear wheel
drum brakes, the brake pedal, springs and brake linkage to
operate the brakes.
These brakes are self-adjusting and should not require
adjustment if shoe-to-drum clearance is within normal limits.
When brakes are applied, shoes expand outward to drum. If
brake shoe travel is excessive, brake adjuster will advance to
compensate for wear. When brakes are released, adjuster
returns to normal position.
To check brake operation, operate the vehicle with no load, in
a large, clear area. Release the accelerator and apply the brake
pedal completely. The vehicle should stop abruptly. If it doesn’t,
see
Mechanical Brake Adjustments
in this section.
The parking brake is applied by depressing the parking brake
pad at the top of the brake pedal which locks the brakes in
place. Brakes are released when the accelerator or brake pedal
is depressed. If brakes fail to hold the car in position when
parking brake is applied, see
Mechanical Brake Adjustments
