FRONT DISC BRAKE
Revision: June 20062007 Versa
2. Apply rubber grease to piston boot and apply brake fluid to pis-
ton. Cover the piston end with piston boot, and install cylinder-
side lip on piston boot properly into groove on cylinder body.
3. Press piston into cylinder body by hand to assemble piston-side
lip on piston boot properly into a groove on piston.
CAUTION:
Press piston evenly and change pressing point to prevent
inner wall of cylinder from being rubbed.
4. Install sliding pins and sliding pin boots to the torque member.
5. If pads, shims and pad retainers were removed, install them to torque member. Refer to BR-25, "
INSTAL-
LATION" .
6. Install cylinder body to torque member.
7. Install sliding pin bolts.
8. Install caliper assembly to vehicle. Refer to BR-26, "
INSTALLATION" .
9. Tighten sliding pin bolts to specified torque. Refer to BR-24, "
Components" .
DISC ROTOR INSPECTION
Visual Inspection
Check surfaces of disc rotor for uneven wear, cracks, and serious damage. Replace applicable part as neces-
sary.
Runout Inspection
1. Using wheel nuts, secure disc rotor to wheels hub 2 or more positions.
2. Using a dial indicator, check runout.
CAUTION:
Make sure that wheel bearing axial end play is within the
specifications before measuring runout. Refer to FA X -5 ,
"FRONT WHEEL BEARING INSPECTION" .
3. If runout is outside the limit, find the minimum runout point by
shifting the mounting positions of disc rotor and wheel hub by
one hole.
SFIA3074E
SFIA2279E
Runout limit : 0.04 mm (0.0016 in) or less
[Measured at 10.0 mm (0.394 in) inside
the disc edge]

Thickness Inspection
1. Using a micrometer, check thickness of disc rotor. If thickness is
outside the standard, replace disc rotor.
2. If runout is still out of the specification, grind rotor with on-car
brake lathe (″MAD, DL-8700″, ″AMMCO 700 and 705″ or equiv-
alent) until runout becomes within the specified limit.
Brake Burnishing ProcedureEFS006JS
Burnish the new braking surfaces according to following procedure after refinishing or replacing disc rotors,
pads, or if a soft pedal occurs at very low mileage.
CAUTION:
Be careful of vehicle speed because brake does not operate easily until pad and disc rotor are
securely fitted.
Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive vehicle on straight, flat road.
2. Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake pedal for a few minutes to cool brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted.Standard thickness : 24.0 mm (0.945 in)
Repair limit thickness : 22.0 mm (0.866 in)
Maximum uneven wear
(measured at 8 positions): 0.02 mm (0.0008 in)
or less

Removal and Installation of Drum Brake AssemblyEFS006JU
REMOVAL
1. Remove tire 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 (A) with a tool to separate operating lever
(C) from brake shoe.
