Removal and Installation of Drum Brake AssemblyEFS006AG
REMOVAL
1. Remove tyre from the vehicle.
2. With the parking brake lever released, remove the brake drum. If it is difficult to remove brake drum,
remove as follows:
a. Press up adjuster lever with a wire or equivalent from plug hole
(plug hole at the side of wheel cylinder) on the back plate as
shown in the figure. Turn frame of adjuster assembly with a flat
bladed screw driver in the direction that narrows frame to narrow
enlarged brake shoe.
3. While pushing and rotating the retainer, pull out shoe hold pin,
and remove shoe assembly.
CAUTION:
Do not damage the wheel cylinder boot.
4. Remove the parking brake rear cable from the operating lever.
CAUTION:
Do not bend the parking brake cable.
5. Disassemble the shoe assembly (shoe, springs, adjuster,
adjuster lever).
6. Remove retainer ring with a tool to separate operating lever from
brake shoe.

REAR DRUM BRAKE
INSPECTION AFTER REMOVAL
Lining Thickness Inspection
Check lining thickness.
Drum Inner Diameter Inspection
Check inner diameter of brake drum.
Measurement area: lining contact surface (center)
Wheel Cylinder Leakage Inspection
lCheck wheel cylinder for brake fluid leakage.
lCheck for wear, damage, and looseness. If any non-standard
condition is found, replace it.
Other Inspections
Check the following:
lInside of the drum for excessive wear, damage, and cracks.
lLining for excessive wear, damage, and peeling.
lShoe sliding surface for excessive wear and damage.
lReturn spring for sagging.
Replace with new part if the above part is malfunction.
lCheck back plate for damage, cracks, and deformation. If malfunction is detected, repair or replace it.Standard thickness (A) : 5.5 mm (0.22 in)
Repair limit thickness (A) : 1.5 mm (0.06 in)
SBR021A
Standard inner diameter : 295 mm (11.61 in) dia.
Repair limit inner diameter : 296.5 mm (11.67 in) dia.

INSTALLATION
1. When removing operating lever, install following procedure.
a. Install operating lever to brake shoe.
b. Install retainer ring to operating lever, and crimp them until their
contact points are met.
2. Apply rubber grease to brake shoes sliding surfaces (the
shaded areas) and other parts on the back plate as indicated by
arrows in the figure.
3. Apply rubber grease to screw and confirm the difference
between right and left wheel for assembling when disassem-
bled.
4. Assemble the shoe, adjuster, adjuster lever and springs to the
shoe assembly.
5. Connect the parking brake rear cable to the operating lever.
6. Install the shoe assembly. After assembly, be sure that each part is installed properly.
CAUTION:
Do not damage the wheel cylinder piston boot.
7. Install the brake drum.
8. Depress brake pedal for several time (approximately 2, 3 time).
9. Adjust clearance of brake shoe. Refer toPB-2, "
ADJUSTMENT".
10. Install tyres to the vehicle.

Removal and Installation of Wheel Cylinder
EFS006AH
REMOVAL
1. Drain brake fluid. Refer toBR-10, "Drain and Refill".
2. Remove rear brake shoe assembly.
3. Remove brake tube from the wheel cylinder.
4. Remove bolts on the wheel cylinder, and then remove wheel cylinder from the back plate.
INSTALLATION
lInstallation is the reverse order of removal. Tighten bolts to the specified torque. Refer toBR-30, "Compo-
nents".
lRefill with new brake fluid and bleed air. Refer toBR-11, "Bleeding Brake System".
Disassembly and Assembly of Wheel CylinderEFS006AI
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:
lDo not use Nissan rubber grease (KRE0000010, KRE000001001) during assembly.
lWhen 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 polyglycol ether based lubricant to the piston cups and
piston boots and assemble as shown in the figure.
