Disassembly and Assembly of Wheel CylinderEFS006JW
DISASSEMBLY
1. Remove boots at the right and left of the wheel cylinder, and pull
out the pistons from cylinder.
2. Remove piston from piston cup.
INSPECTION AFTER DISASSEMBLY
Check the pistons, piston cups, and inner wall of the cylinder for wear, corrosion, and damage. If malfunction
is detected, replace it.
ASSEMBLY
CAUTION:

Do not use Nissan rubber grease (KRE0000010, KRE000001001) during assembly.

When inserting the piston, be careful not to scratch the cylinder.
1. Apply brake fluid to the piston sliding surface on the wheel cylinder.
2. Apply Nissan rubber lubricant (KRE1200030) to the piston cups
and piston boots and assemble as shown.

SYSTEM DESCRIPTIONPFP:00000
System ComponentsEFS006LC
ABS FunctionEFS006LD

The Anti-Lock Brake System detects wheel revolution while braking and improves handling stability during
sudden braking by electrically preventing wheel lockup. Maneuverability is also improved for avoiding
obstacles during emergency braking.

If the electrical system malfunctions, the Fail-Safe function is activated, the ABS becomes inoperative and
the ABS warning lamp turns on.

The electrical system can be diagnosed using CONSULT-II.

During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.

Just after starting the vehicle, the brake pedal may vibrate or motor operating noises may be heard from
the engine compartment. This is normal due to the self check operation.

Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
EBD FunctionEFS006LE

Electronic Brake Distribution is a function that detects subtle slippages between the front and rear wheels
during braking, and it improves handling stability by electronically controlling the brake fluid pressure
which results in reduced rear wheel slippage.

If the electrical system malfunctions, the Fail-Safe function is activated, the EBD and ABS become inoper-
ative, and the ABS warning lamp and brake warning lamp are turned on.

The electrical system can be diagnosed using CONSULT-II.

During EBD operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.

Just after starting the vehicle, the brake pedal may vibrate or motor operating noises may be heard from
the engine compartment. This is normal due to the self check operation.
