BRAKE PEDAL
Revision: 2006 January2006 M35/M45
WITH PRE-CRASH SEAT BELT
NOTE:
Clevis pin can be installed from both left and right.
REMOVAL
1. Remove instrument driver lower panel. Refer to IP-10, "INSTRUMENT PANEL ASSEMBLY" .
2. Remove steering column assembly. Refer to PS-13, "
STEERING COLUMN" .
3. Disconnect stop lamp switch and brake switch connector.
4. Remove stop lamp switch and brake switch from brake pedal assembly.
5. Disconnect brake pedal stroke sensor connector.(With pre-crash seat belt)
CAUTION:
Brake pedal stroke sensor is not detachable. Do not detach it.
6. Remove snap pin and clevis pin from clevis of brake booster.
7. Remove brake pedal assembly mounting nuts. Pull brake booster toward engine room to the extent that
does not deform brake tube.
8. Remove brake booster clevis from input rod.
9. Remove mounting bolt and then remove brake pedal assembly from vehicle.
INSPECTION AFTER REMOVAL
Check brake pedal upper rivet for deformation.
Make sure that joint length (L) of sub-bracket and sliding plate is
4 mm (0.16 in) or more.
Check brake pedal for bend, damage, and cracks on the welded
parts.
Replace brake pedal assembly if any non-standard condition is
detected.

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. Standard thickness : 11.0 mm (0.433 in)

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.
