LEVEL CHECK

Make sure the fluid level in reservoir tank is within the standard
(between MAX and MIN lines).

Visually check around reservoir tank for fluid leaks.

If fluid level is excessively low, check brake system for leaks.

If brake warning lamp remains illuminated after parking lever is
released, check brake system for fluid leakage.
Drain and RefillAFS001MW
CAUTION:

Refill with new brake fluid “DOT3”.

Do not reuse drained brake fluid.

Do not let brake fluid splash on the painted surfaces of the body. This might damage the paint, so
when splashing it, immediately wipe off the area and wash away with water.

Before servicing, disconnect actuator connector or battery negative cable.
1. Connect a vinyl tube to each bleed valve.
2. Depress brake pedal, loosen each bleed valve, and gradually
remove brake fluid.
3. Make sure there is no foreign material in reservoir tank, and refill
with new brake fluid.
4. Rest foot on brake pedal. Loosen bleed valve. Slowly depress
pedal until it stops. Tighten bleed valve. Release brake pedal.
Repeat this process a few times, then pause to add new brake
fluid to master cylinder. Continue until new brake fluid flows out.
Bleed Air. Refer to BR-10, "
Bleeding Brake System" .

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-24, "
BRAKE BURNISHING PROCEDURE" .
Removal and Installation of Brake PadAFS001RZ
REMOVAL

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.

Bleeding Brake System" .
5. Attach tires to the vehicle.
Disassembly and Assembly of Brake Caliper AssemblyAFS001S1
DISASSEMBLY
1. Remove sliding pin bolt, and then remove the pad, shim, shim cover, and pad retainer from the torque
member.
2. Remove sliding pins and sliding pin boots from torque member.
3. Place a wooden block as shown in the figure, and blow air from
union bolt mounting hole to remove pistons and piston boots.
CAUTION:
Do not get your fingers caught in piston.
4. Using a flat-bladed screwdriver, remove piston seal from cylin-
der body.
CAUTION:
Be careful not to damage cylinder inner wall.

CALIPER INSPECTION
Cylinder Body
CAUTION:

Use new brake fluid for cleaning. Do not use mineral oils such as gasoline or kerosene.

Check inside surface of cylinder for score, rust, wear, damage or foreign materials. If any of the
above conditions are observed, replace cylinder body.

Minor damage from rust or foreign materials may be eliminated by polishing surface with a fine
emery paper. Replace cylinder body if necessary.
To r q u e M e m b e r
Check for wear, cracks, and damage. If damage or deformation is present, replace the affected part.
Piston
Check piston for score, rust, wear, damage or presence of foreign materials. Replace if any of the above con-
dition are observed.
CAUTION:
Piston sliding surface is plated, do not polish with emery paper even if rust of foreign materials are
stuck to sliding surface.
Sliding Pins, and Sliding Pin Boots
Check sliding pin and sliding pin boot for wear, damage, and cracks. If damage or deformation is present,
replace the affected part.
ASSEMBLY
CAUTION:
Do not use NISSAN Rubber Grease (KRE00 00010, KRE00 00010 01) when assembling.
1. Apply rubber grease to new piston seal and insert seal in to
groove on cylinder body.
CAUTION:
Do not reuse piston seal.
2. Apply brake fluid to piston, rubber grease to piston boot, then
install piston boot in to piston groove.
CAUTION:
Do not reuse piston boot.
3. Insert into cylinder body by hand and insert piston boot piston-side lip into piston groove.
CAUTION:
Press piston evenly and vary the pressing point to prevent cylinder inner wall from being rubbed.
4. Install sliding pins and sliding pin boots to torque member.
5. Attach inner shim and inner shim cover to inner pad, and attach the outer shim to the outer pad.
6. Install cylinder body. Tighten sliding pin bolt to the specified torque.
