ABS Actuator and Electric Unit Brake Pipe Connections for VK56DE
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-18, "FOR USA AND CANADA : Fluids and Lubri-
MA-20, "FOR MEXICO : Fluids and Lubricants"
(Mexico).
• Do not reuse drained brake fluid.

2. Loosen lock nut (A) on the input rod, then turn input rod to adjust
the brake pedal to specified height. When finished adjusting,
tighten 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 threaded ends
contact the brake pedal bracket.
4. With the threaded ends of the stop lamp switch and ASCD can-
cel switch contacting the pedal bracket, turn the switches 45
°
clockwise 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.

LEVEL CHECK
• Check that the brake fluid level in the reservoir tank is within speci-
fication, between the MAX and MIN lines as shown.
• Visually check around reservoir tank for fluid leaks.
• If fluid level is excessively low, check brake system for leaks.
• If brake warning lamp remains illuminated after the parking brake
pedal is released, check the brake system for any brake fluid
leaks.
Drain and Refill
INFOID:0000000006245713
CAUTION:
• Refill with new brake fluid. Refer to
MA-18, "FOR USA AND CANADA : Fluids and Lubricants"
States and Canada),
MA-20, "FOR MEXICO : Fluids and Lubricants"
• Do not reuse drained brake fluid.
• Do not let brake fluid splash on the painted surfaces of the body. This might damage the paint, so
when splashing it, immediately wipe off the area and wash away with water.
• Before servicing, disconnect ABS actuator and electric unit (control unit) connector or battery nega-
tive terminal.
1. Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector or battery
negative terminal.
2. Connect a vinyl tube to each bleed valve.
3. Depress brake pedal, loosen each bleed valve, and gradually
remove brake fluid.
4. Make sure there is no foreign material in reservoir tank, and refill
with new brake fluid.
5. Rest foot on brake pedal. Loosen bleed valve. Slowly depress
brake pedal until it stops. Tighten bleed valve. Release brake
pedal. Repeat the process a few times, then pause to add new
brake fluid to master cylinder. Continue until the new brake fluid
flows out of the bleed valve.
Bleed the air out of the brake hydraulic system. Refer to
.
