CAUTION:
• All hoses and piping (tubes) must be fr ee 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-12, "
Fluids and Lubricants".
• Do not reuse drained brake fluid.

INSPECTION
1. Inspect the brake pedal free height (H) from the floor using Tool at a 90 ° angle to the floor as shown.
2. Adjust the brake pedal height to specifications. CAUTION:
When equipped with adjustable pedal, the pedal must be in
the forward most (closest to th e floor) position for pedal
height measurement.

Unit: mm (in)
ADJUSTMENT
1. Loosen the stop lamp switch and ASCD cancel switch by turning them 45° counterclockwise.

2. Loosen lock nut (A) on the input rod, then turn input rod to adjustthe brake pedal to the specified height. When finished adjusting,
tighten the lock nut (A) to specification.
CAUTION:
Make sure that the screw portion of the end of input rod is
located inside the clevis.
3. With the brake pedal pulled up and held by hand, press the stop lamp switch and the ASCD cancel switch in until the threaded
ends contact the brake pedal bracket.
4. With the threaded ends of the stop lamp switch and ASCD switch contacting the pedal bracket, turn the switches 45 ° clock-
wise to lock in place. Check that the stop lamp switch and ASCD
cancel switch threaded end to brake pedal bracket gap (C) is
within specifications.
CAUTION:
Make sure that the gap (C) between the brake pedal bracket
and stop lamp switch and ASCD cancel switch threaded
ends are within specification.
5. Check the brake pedal for smooth operation. CAUTION:
Make sure that the stop lamp goes off when the brake pedal
is released.Lock nut (A) : 18.7 N·m (1.9 kg-m, 14 ft-lb)
