FRONT DISC BRAKE
Revision: 2006 January2006 M35/M45
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 shim and shim cover as a set when replacing brake pads.
Keep rotor free from brake fluid.
Burnish the brake pads and disc rotor mutually contacting surfaces, after refinishing or replacing
rotors, after replacing pads, or if a soft pedal occurs at very low mileage. Refer to BR-28, "
BRAKE
BURNISHING PROCEDURE" .
Removal and Installation of Brake PadNFS000PD
REMOVAL
1. Remove tires from vehicle with power tool.
2. Remove lower sliding pin bolt.
3. Hang cylinder body with a wire, and remove pads, pad retainers,
shims, and shim cover from torque member.
CAUTION:
When removing the pad retainer from the torque member,
lift it in the direction indicated by the arrow in the figure so
that it does not deform.
INSTALLATION
1. Apply PBC (Poly Butyl Cuprysil) grease or equivalent to between shim cover and shim. Install shim, shim
cover, to pad.
2. Apply PBC (Poly Butyl Cuprysil) grease or equivalent to
between pad retainer and pad. Install pad retainers and pads to
torque member.
CAUTION:
Securely assemble pad retainers so that they are not
being lifted up from torque member.
Both inner and outer pads have a pad return system on
the pad retainer. Install pad return lever securely to pad
wear sensor.
3. Install cylinder body to torque member.
CAUTION:
In the case of replacing a pad with new one, check a brake fluid level in the reservoir tank because
brake fluid returns to master cylinder reservoir tank when pressing piston in.
NOTE:
Use a disc brake piston tool (commercial service tool) to easily press piston.
4. Install lower sliding pin bolt, and tighten it to the specified torque. Refer to BR-23, "
Components" .
5. Check front disc brake for drag.
6. Install tires to vehicle.

torque. Refer to BR-23, "
Components" .
CAUTION:
Do not allow oil or any moisture on all contact surfaces between steering knuckle and caliper
assembly, bolts, and washer.
3. Install brake hose to brake caliper assembly, and tighten union
bolts to the specified torque. Refer to BR-13, "
Removal and
Installation of Front Brake Tube and Brake Hose" .
4. Refill with new brake fluid and bleed air. Refer to BR-11, "
Bleed-
ing Brake System" .

ASSEMBLY
1. Apply polyglycol ether based lubricant to piston seal, and install
them to cylinder body.
CAUTION:
Do not reuse piston seal.
2. Apply rubber grease to piston boot. Cover the piston end with
piston boot, and then install cylinder side lip on piston boot
securely into a groove on cylinder body.
CAUTION:
Do not reuse piston boot.
3. Apply brake fluid to piston. Push piston into cylinder body by
hand and push 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.
4. Install sliding pins and sliding pin boots to torque member.
5. Install torque member to steering knuckle, and tighten mounting bolts to the specified torque. Refer to BR-
23, "Components" .
CAUTION:
Do not allow oil or any moisture on all contact surfaces between steering knuckle and brake cali-
per assembly.
6. Press in piston until pads can be installed, and then install cylinder body to torque member.
7. Tighten sliding pin bolts to the specified torque. Refer to BR-23, "
Components" .

WAR NING :
Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of air borne
particles or other materials.
CAUTION:
While removing cylinder body, do not 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 shim and shim covers as a set when replacing brake pads.
Keep rotor free from brake fluid.
Burnish the brake pads and disc rotor mutually contacting surfaces after refinishing or replacing
rotors, after replacing pads, or if a soft pedal occurs at very low mileage. Refer to BR-34, "
BRAKE
BURNISHING PROCEDURE" .

REMOVAL
1. Remove tires from vehicle with power tool.
2. Remove lower sliding pin bolt.
3. Hang cylinder body with a wire, and remove pads, pad retainers, shims, and shim cover from torque mem-
ber.
CAUTION:
