BODY REPAIR
Revision: 2005 July2005 FX
PANEL PARTS MATCHING MARKS
A mark has been placed on each body panel to indicate the parts matching positions. When repairing parts
damaged by an accident which might affect the vehicle structure (members, pillars, etc.), more accurate and
effective repair will be possible by using these marks together with body alignment specifications.

WARNING:
Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of airborne
particles or other materials.
CAUTION:

While removing cylinder body never depress brake pedal because piston will pop out.

It is not necessary to remove bolts on torque member and brake hose except for disassembly or
replacement of caliper assembly. In this case, hang cylinder body with a wire so as not to stretch
brake hose.

Do not damage piston boot.

If any shim is subject to serious corrosion, replace it with a new one.

Always replace shims and shim covers as a set when replacing brake pads.

Burnish brake contact surface after refinishing or replacing rotors, after replacing pads, or it a soft
pedal occurs at very low mileage. Refer to BR-25, "
BRAKE BURNISHING PROCEDURE" .
Removal and Installation of Brake PadAFS001RZ
REMOVAL
1. Remove tires from vehicle with power tool.
2. Remove lower sliding pin bolt.
3. Suspend cylinder body with a wire and remove pad and shim from torque member.
INSTALLATION
1. Attach inner shim and shim cover to inner pad, and outer shim to outer pad.
2. Push piston in so that pad is firmly installed and mount cylinder body to torque member.
NOTE:
Using a disc brake piston tool (commercial service tool), etc., makes it easier to push in piston.
CAUTION:
By pushing in piston, brake fluid returns to master cylinder reservoir tank. Watch the level of the
surface of reservoir tank.
3. Attach pat retainer to torque member.
CAUTION:
When attaching pad retainer, attach it firmly so that it does
not float up higher than torque member, as shown in the fig-
ure.
4. Install lower sliding pin bolt and tighten it to the specified torque.
5. Check brake for drag.
6. Attach tires to the vehicle.

slowly of less than 2 (2-1/8 US qt, 1-3/4 lmp qt) a minute
to allow air in system to escape.

Use Genuine Nissan Long Life Antifreeze/Coolant or
equivalent mixed with water (distilled or demineralized).

RECOMMENDED FLUIDS AND LUBRI-
CANTS" .

When engine coolant overflows air relief hole on heater hose,
install air relief plug with new O-ring.
