Bleeding Brake SystemNFS0000A
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.

of the piston assembly.
2. Insert the secondary piston assembly and primary piston
assembly into cylinder body in this order.
CAUTION:

Do not reuse the primary and secondary piston assem-
blies.

Be sure to replace the assembly without disassembling
the new inner kit.

Pay attention to the orientation of the piston cup, and
insert straight to prevent the cup from being caught by
cylinder inner wall.
3. Perform a visual inspection of the secondary piston slit through
the tank boss hole on the secondary-side of the cylinder body,
and install the piston stopper.
4. Holding down the piston with the stopper cap, push the stopper
cap tabs so they are firmly into the cylinder grooves, then attach
the stopper cap.
CAUTION:
Do not reuse the stopper cap.
5. Apply brake fluid the grommet and attach to the cylinder body.
CAUTION:
Do not reuse the grommet.
