Check the brake pedal for bend, damage, and cracks on the
welded parts. Replace the applicable part if a failure is detected.

Check the clevis pin and resin stopper for damage and deforma-
tion. If a failure is detected, replace the clevis pin.

On-Vehicle InspectionNFS00008
LEVEL CHECK

Check that the fluid level in the reservoir tank is within the stan-
dard (between MAX and MIN lines).

Visually check around the reservoir tank for fluid leaks.

If fluid level is excessively low, check brake system for leaks.

If warning lamp remains illuminated after parking lever is
released, check brake system for fluid leakage.
Drain and RefillNFS00009
CAUTION:

Refill with new brake fluid “DOT3”.

Do not reuse drained brake fluid.

Do not let brake fluid come in contact with painted surfaces on the body. This might damage the
paint, so if it does come in contact, immediately wipe area and wash off with water.
1. Connect a vinyl tube to bleed valve.
2. Depress the brake pedal, loosen the bleed valve, and gradually
remove the brake fluid.
3. Before working, turn the ignition switch OFF and disconnect the
connectors of ABS actuator and control unit or battery negative
terminal.
4. Make sure there is no foreign material in the reservoir tank, and
refill with new brake fluid.
5. Rest foot on brake pedal. Loosen bleed valve. Slowly depress
pedal until it stops. Tighten bleed valve. Release brake pedal.
Repeat this process a few times, then pause to add new brake
fluid to master cylinder. Continue until new brake fluid flows out.

CAUTION:
While bleeding, pay attention to master cylinder fluid level.
1. Before working, turn the ignition switch OFF and disconnect the connectors of ABS actuator and control
unit 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 the brake pedal depressed, loosen the bleed valve to let the air out, and then tighten it immediately.
5. Repeat steps 3, 4 until no more air comes out.
6. Tighten the bleed valve to the specified torque. Refer to BR-27, "
Components" (Front) and BR-40, "Com-
ponents" (Rear).
7. In steps 2 to 6 below, with the master cylinder reservoir tank filled at least half way, bleed air from the front
left, rear left, and front right tires, in that order.

BRAKE TUBE AND HOSEPFP:46300
Hydraulic CircuitNFS0000B
CAUTION:

Make sure it does not twist or break when being attached.

Make sure there is no interference with other parts when turning steering both clockwise and
counterclockwise.

The brake tube 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.

Do not let brake fluid come in contact with painted surfaces on the body. This might damage the
paint, so if it does come in contact, immediately wipe area and wash off with water.

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 brake fluid “ DOT 3 ”.

Do not reuse drained brake fluid.
