ABS Actuator and Electric Unit Brake Pipe Connections for VQ40DE

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-16, "For North America"

.

• Do not reuse drained brake fluid.

BRAKE TUBE AND HOSE

1. Check brake lines (tubes and hoses) and connections for fluid leaks, damage, twists, deformation, contact

with other parts, and loose connections. Replace any parts as necessary. Refer to

cuit"

.

2. While depressing brake pedal under a force of 785 N (80 kg-f, 177 lb-f) with engine running for approxi-

mately 5 seconds, check each part for fluid leaks.

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.

6. Start the engine and check the height of the brake pedal when depressing it.

INFOID:0000000005260203

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:0000000005260204

CAUTION:

• Refill with new brake fluid. Refer to 

MA-16, "For North America"

.

• 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 

BR-20,

"Bleeding Brake System"

.

• 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.

• While bleeding, monitor the master cylinder brake fluid level.

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 the rear right bleed valve.
3. Fully depress brake pedal 4 to 5 times.
4. With brake pedal depressed, loosen bleed valve to let the air out, and then tighten it immediately.
5. Repeat steps 3 and 4 until no more air comes out.
6. Tighten bleed valve to the specified torque. Refer to 

BR-40, "Exploded View of Brake Caliper"

 (front disc

brake), 

BR-45, "Exploded View of Brake Caliper"

 (rear disc brake). 

7. Perform steps 2 to 6 at each wheel, with master cylinder reservoir tank filled at least half way, bleed air

from the front left, rear left, and front right bleed valve, in that order.
