LEAK INSPECTION

Check for leaking in a master cylinder installation surface, a reservoir tank installation surface, and brake
tube connections.
Removal and InstallationNFS000S4
CAUTION:

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.

Never scratch the piston of master cylinder when installing/removing because the piston is
exposed. Check if any dust is not on the piston, and wash with brake fluid if needed.

Hold cylinder body when handing master cylinder. Never hold the piston because the piston might
be detached if pulled strongly.
REMOVAL
1. Drain brake fluid. Refer to BR-9, "Drain and Refill" .
2. Disconnect brake fluid level switch harness connector.
3. Disconnect master cylinder brake tubes, using a flare nut wrench.
4. Remove master cylinder mounting nuts and remove master cylinder assembly from vehicle.
INSTALLATION
CAUTION:

Refill with new brake fluid “DOT 3”.

Never reuse drained brake fluid.
1. Installation is in the reverse order of removal.
CAUTION:
Apply silicone grease to brake booster (to “A” position in
the figure) when installing master cylinder to brake booster.
2. Tighten brake tube flare nut to the specified torque using a flare
nut torque wrench. Refer to BR-11, "
Hydraulic Circuit" .
3. Refill with new brake fluid and bleed air. Refer to BR-10, "
Bleed-
ing Brake System" .

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-27, "
BRAKE
BURNISHING PROCEDURE" .
Removal and Installation of Brake PadNFS000SE
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 silicone-based grease to between pad and shim. Install shim,
shim cover, to pad.
2. Apply PBC (Poly Butyl Cuprysil) grease or silicone-based
grease 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-22, "
Components" .
5. Check front disc brake for drag.
6. Install tires to vehicle.

bling cylinder body assembly.
DISASSEMBLY
1. Remove sliding pin bolt, and then remove cylinder body from torque member.
CAUTION:
Do not drop pads, shims, shim covers and pad retainers from torque member.
2. Remove sliding pins and sliding pin boots from torque member.

INSPECTION AFTER DISASSEMBLY
Cylinder Body
Check the inner wall of cylinder for corrosion, wear, and damage. If a malfunction is detected, replace cylinder
body.
CAUTION:
Clean cylinder body using new brake fluid. Never use mineral oils such as gasoline or kerosene.
To r q u e M e m b e r
Check torque member for wear, cracks, and damage. Replace if there are.
Piston
Check the piston surface for corrosion, wear, and damage. If a malfunction is detected, replace applicable
part.
CAUTION:
