NOTE:
Refer to BR-43, "
HOW TO APPLY GREASE TO THE BRAKE PAD" for how to apply grease to brake pads.
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 the brake pedal because the piston will pop out.

Apart from caliper assembly, disassembly or replacement, there is no need to remove caliper bolts
or brake hose or tube.

Do not damage piston boot.

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

Keep disc rotor clean of brake fluid.

Removal and Installation of Brake Pad (Other than Brembo Calipers)NFS00011
REMOVAL
1. Remove tires from vehicle with a power tool.
2. Remove sliding pin bold (one on top).
3. Hang cylinder body with a wire, and remove pads, pad retainers, shims and shim cover from torque mem-
ber.
INSTALLATION
1. 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.
2. Attach the pad retainer and pad to the torque member.
3. Push the piston in so that the pad is firmly attached and attach the cylinder body to the torque member.
NOTE:
Using a disc brake piston tool (commercial service tool), etc., makes it easier to push in the piston.
CAUTION:
By pushing in the piston, the brake fluid returns to the master cylinder reservoir tank. Watch the
level of the surface of the reservoir tank.
4. Attach the sliding pin bolt (one on top) and tighten to the specified torque.
5. Check brake for drag.
6. Install tires to vehicle.

HOW TO APPLY GREASE TO THE BRAKE PAD
Pad Side
Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease
about 0.5 g (0.018 oz) per surface equally to back plate side of Inner
Pad and Outer Pad. (Refer to the figure)
CAUTION:
Make sure no foreign matter attaches itself to the grease.
Pad Rear
Apply approximately 1.5 g (0.053 oz) of PBC (Poly Butyl Cuprysil)
grease or silicone -based grease between shim cover (1) and pad
(2).

A: Outer side

B: Inner side
CAUTION:
Make sure no foreign matter attaches itself to the grease.
INSTALLATION
1. Insert the piston to the position where the pad is attached.
NOTE:
Using a disc brake piston tool (commercial service tool), etc., makes it easier to push in the piston.
CAUTION:
Pushing the piston in will make the brake fluid return to the master cylinder reservoir tank, so
watch the level of the surface of the reservoir tank.
2. Attach pad and shim cover.

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.

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.

7. Install the pad retainers and pads to the torque member.
CAUTION:
When attaching the pad retainer, attach it firmly so that it
does not float up higher than the torque member, as shown
in the figure.
8. After assembling shims and shim cover to pad, install it to the
torque member.
9. Install cylinder body. Tighten sliding pin bolts to the specified
torque. Refer to BR-40, "
Components" .
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 specification before measuring runout. Refer to
RAX-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.]
Thickness Inspection
Using a micrometer, check thickness of the disc rotor. If thickness is
outside the standard, replace disc rotor.
