pedal electric motor.

• Unlock (1) then pull (2) the adjustable brake pedal cable to dis-

connect it from the adjustable pedal electric motor as shown.

4. Remove snap pin and clevis pin from the clevis of brake booster.
5. Remove brake pedal assembly nuts and remove the brake pedal assembly.

• Temporarily install the brake pedal assembly nuts by hand to support the brake booster.

WARNING:

Do not bend the brake tubing.

CAUTION:

• Before removal and installation, the accelerator and brake pedals must be in the forward most

position (closest to the floor). This is to align the base position of the accelerator and brake ped-

als.

• Do not disassemble the brake pedal adjusting mechanism.

• Avoid damage from dropping the brake pedal assembly during handling.

• Keep the brake pedal assembly away from water.

INSPECTION AFTER REMOVAL

Check the brake pedal assembly for the following items:

• Crack or deformation of clevis pin stopper

• Clevis pin deformation

• Crack of any welded portion of the brake pedal assembly

• Brake pedal bend or deformation

INSTALLATION

Installation is in the reverse order of removal.

• Check the brake pedal for smooth operation. There should be no binding or sticking when applying or

releasing the brake pedal.

• Check the brake pedal adjustable feature for smooth operation. There should be no binding or sticking when

adjusting the brake pedal forward or backward.

• After installing the brake pedal assembly, be sure to adjust it. Refer to

INFOID:0000000005147905

CAUTION:

• All hoses and piping (tubes) must be free from excessive bending, twisting and pulling.

• Make sure there is no interference with other parts when turning the steering wheel both clockwise

and counterclockwise.

• The brake piping is an important safety part. If a brake fluid leak is detected, always disassemble the

parts. Replace applicable part with a new one, if necessary.

• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is

splashed on painted areas, wash it away with water immediately.

• Do not bend or twist brake hose sharply, or strongly pull it.

• When removing components, cover connections so that no dirt, dust, or other foreign matter gets in.

• Refill with new specified brake fluid. Refer to 

MA-13, "Fluids and Lubricants"

.

• Do not reuse drained brake fluid.
