3. As shown in the figure, using a flat-bladed screwdriver, remove
the retaining ring from the cylinder body.
4. 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 fingers caught in the piston.
5. Using a flat-bladed screwdriver, remove piston seals from cylin-
der body.
CAUTION:
Be careful not to damage cylinder inner wall.
CALIPER INSPECTION
Cylinder Body
CAUTION:

Use new brake fluid to clean. Never use mineral oils such as gasoline or kerosene.

Check inner wall of cylinder for corrosion, wear, and damage. If any non-standard condition is
detected, replace cylinder body.

Minor flaws caused by corrosion or a foreign material can be removed by polishing the surface
with a fine sandpaper. Replace the 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
CAUTION:
Since the piston surface is plated, do not repair using sandpaper.
Check piston surface for corrosion, wear, and damage. If any non-standard condition is detected, replace
applicable part.
Sliding Pin Bolts and Sliding Pin Boots
Check that there is no wear, damage, or cracks in the sliding pin bolts and sliding pin boots, and if there are,
replace them.

ASSEMBLY
1. Apply polyglycol ether based lubricant to the piston seal, and
install them to the cylinder body.
CAUTION:
Do not reuse piston seal.
2. Apply rubber grease to piston boot. Cover the piston end with
the piston boot, and then install cylinder slide lip on the piston
boot securely into the groove on cylinder body.
CAUTION:
Do not reuse the piston boot.
3. Apply a brake fluid to the piston, insert into the cylinder body by
hand and firmly attach the piston boot piston-side lip into the pis-
ton groove.
CAUTION:
Press the piston evenly and vary the pressing point to pre-
vent cylinder inner wall from being rubbed.
4. Fix piston boot with retaining ring.
CAUTION:

Make sure the boot is firmly in the cylinder body groove.

Do not reuse the retaining ring.
5. Install the sliding pin bolt and sliding pin boot to the torque member.
6. Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease to the rear of the pad and to both sides
of the shim, and attach the inner shim and shim cover to the inner pad, and the outer shim to the outer
pad.

Disassembly and Assembly of Brake Caliper Assembly (With Brembo Calipers)NFS00018
DISASSEMBLY
1. Insert a piece of wood as shown in the figure, blow air in through
the flare nut mounting hole, and remove the piston and piston
boot.
CAUTION:
Do not get fingers caught in the piston.
2. Remove the piston boot from the piston.
3. Using a flat-bladed screwdriver, remove the piston seal.
CAUTION:

Be careful not to damage cylinder inner wall.

Never remove the four bolts from the inner and outer
sides of the caliper. Do not tighten them further, either.
CALIPER INSPECTION
Caliper
CAUTION:

Use new brake fluid to clean. Never use mineral oils such as gasoline or kerosene.

Check for corrosion, wear, or damage to the cylinder inner wall, and replace the caliper if there are
any non-standard conditions.
Piston
CAUTION:

Since the piston surface is plated, do not repair using sandpaper.

Check piston surface for corrosion, wear, and damage. If any non-standard condition is detected,
replace applicable part.
ASSEMBLY
1. Apply polyglycol ether based lubricant to the piston seal (1), and
install them to the cylinder body.
CAUTION:
Do not reuse piston seal.

2. Apply rubber grease to the piston boot, place it on the piston,
and firmly insert the piston boot cylinder-side lip into the cylinder
body groove.
3. Insert the piston into the cylinder body by hand and firmly attach
the piston boot piston-side lip into the piston groove.
CAUTION:
Press the piston evenly and vary the pressing point to pre-
vent cylinder inner wall from being rubbed.
DISC ROTOR INSPECTION
Visual Inspection
Check surface of the disc rotor for uneven wear, cracks, and serious damage. If any non-standard condition is
detected, replace applicable part.
Runout Inspection
1. Using wheel nuts, fix disc rotor to the wheel hub. (2 or more positions)
2. Inspect runout using a dial gauge.
NOTE:
Make sure that wheel bearing axial end play is with in the speci-
fication before measuring runout. Refer toRAX-6, "
On-Vehicle
Inspection" .
3. If runout is outside the limit, find the minimum runout point by shifting mounting positions of the disc rotor
and wheel hub by one hole.
4. If runout is still outside the limit after performing the above operation, replace or lathe the disc rotor.
[When lathing, use the Pro–Cut PFM On–Car Brake Lathe (Tool No. 38–PFM90.5) or equivalent.]
