BRAKE PEDAL

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
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.

Inspection and Adjustment - Adjustable Pedal

INFOID:0000000004375895

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 height referring to the following specifications.

CAUTION:

When equipped with adjustable pedal, the pedal must be in
the forward most (closest to the floor) position for pedal

BRAKE FLUID

On Board Inspection

INFOID:0000000003937493

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:0000000003937497

CAUTION:

• Refill with new brake fluid. Refer to 

MA-12, "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 

BR-20,

"Bleeding Brake System"

.

Bleeding Brake System

INFOID:0000000003937498

• 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-39, "Exploded View of Brake Caliper"

 (front disc

brake), 

BR-44, "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.
