CAUTION:
All brake hoses and tubes must be free from excessive bending, twisting and pulling.
Make sure that there is no interference with other parts when turning steering both clockwise and
counterclockwise.
Brake tubes and hoses are an important safety part. Always disassemble the parts and retighten
their fittings, if a brake fluid leak is detected. Replace applicable part with a new one, if damaged
part is detected.
Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.
Cover the open end of brake tubes and hoses when disconnecting to prevent entrance of dirt.
Refill with new brake fluid “DOT 3”.
Never reuse drained brake fluid.

Inspection after InstallationNFS000P1
CAUTION:
Brake tubes and hoses are important safety parts. Always disassemble the parts and retighten their fit-
tings, if a brake fluid leak is detected. Replace applicable part with a new one, if damaged part is
detected.
1. Check brake lines (tubes and hoses) and connections for fluid leakage, damage, twists, deformation, con-
tacts with other parts, and loose connections. Replace any damage parts.
2. While depressing brake pedal under a force of 785 N (80 kg, 177 lb) with engine running for approximately
5 seconds, then check each part for fluid leakage.

mately 4 mm (0.16 in)], remove mounting pin on reservoir tank.
2. Remove reservoir tank and grommet from cylinder body.

ASSEMBLY
CAUTION:
Never use mineral oils such as kerosene, gasoline during the cleaning and assembly process.
Do not drop parts. If a part is dropped, do not use it.
1. Apply brake fluid to the grommet and attach it to the cylinder body.
CAUTION:
Do not reuse grommet.
2. Install reservoir tank onto the cylinder body.
3. Secure master cylinder assembly into a vise with a chamfered
pin insert hole on cylinder body facing upward.
4. Tilt reservoir tank as shown in the figure and insert mounting pin.
Return reservoir tank to a upright position when mounting pin
passes through the pinhole in the cylinder body. Push the
mounting pin to the opposite pinhole of the reservoir tank so that
it is the same conditions as the insertion side.
CAUTION:
Be sure to fix the flange part with the brake tube installa-
tion side of cylinder body up.
Do not reuse mounting pin.

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.

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, "

FRONT DISC BRAKE
Revision: 2006 January2006 M35/M45
DISC ROTOR INSPECTION
Visual Inspection
Check surface of disc rotor for uneven wear, cracks, and serious damage. Replace if there are.
Runout Inspection
1. Fix disc rotor to wheel hub using wheel nuts (2 or more posi-
tions).
2. Inspect runout using a dial gauge. [Measured at 10 mm (0.39 in)
inside the disc edge.]
NOTE:
Before measuring, make sure that wheel bearing axial end play
is within the specification. Refer to FA X - 5 , "
WHEEL BEARING
INSPECTION" .
3. When runout exceeds limit value, displace mounting positions of
disc rotor by one hole. And then find a position of the minimum value for runout.
4. Replace or lathe disc rotor if runout is outside the specified value after performing the above operation.
(“MAD DL-8700”, “AMMCO 700 and 705” or equivalent.)
Thickness Inspection
Check thickness of the disc rotor using a micrometer. Replace disc
rotor if thickness is under the wear limit.
BRAKE BURNISHING PROCEDURE
Burnish contact surfaces between disc rotors and pads according to following procedure after refinishing or
replacing rotors, after replacing pads, or if a soft pedal occurs at very low mileage.
CAUTION:
Be careful of vehicle speed because the brake does not operate easily until pad and disc rotor are
securely fitted.
Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive vehicle on straight, flat road.
2. Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake for a few minutes to cool the brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted. Runout limit : 0.035 mm (0.0014 in)
(with it attached to the vehicle)
