< BASIC INSPECTION >

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-

cants"

(United States and Canada)

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

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.

On Board Inspection

INFOID:0000000007356615

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:0000000007356616

CAUTION:

• Refill with new brake fluid. Refer to

MA-18, "FOR USA AND CANADA : Fluids and Lubricants"

(United

States and Canada),

MA-20, "FOR MEXICO : Fluids and Lubricants"

(Mexico).

• Do not reuse drained brake fluid.

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

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

• 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

BR-20,

"Bleeding Brake System"

Bleeding Brake System

INFOID:0000000007356617

CAUTION:

• Refill with new brake fluid. Refer to
