Bleeding Brake SystemNFS0000A
CAUTION:
While bleeding, pay attention to master cylinder fluid level.
1. Before working, turn the ignition switch OFF and disconnect the connectors of ABS actuator and control
unit or battery negative terminal.
2. Connect a vinyl tube to the rear right bleed valve.
3. Fully depress brake pedal 4 to 5 times.
4. With the brake pedal depressed, loosen the bleed valve to let the air out, and then tighten it immediately.
5. Repeat steps 3, 4 until no more air comes out.
6. Tighten the bleed valve to the specified torque. Refer to BR-27, "
Components" (Front) and BR-40, "Com-
ponents" (Rear).
7. In steps 2 to 6 below, with the master cylinder reservoir tank filled at least half way, bleed air from the front
left, rear left, and front right tires, in that order.

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-38, "
Brake
Burnishing Procedure" .
Removal and Installation of Brake Pad (Other than Brembo Calipers)NFS000AU
REMOVAL
1. Remove tires from vehicle with a power tool.
2. Remove lower sliding pin bolt.
3. Hang cylinder body with a wire, and remove pads, shims and
pad retainers from torque member.
CAUTION:

When removing pad retainer from torque member, lift pad
retainer in the direction shown by arrow (shown in the
figure) so as not to deform it.

Do not damage piston boot.

Keep disc rotor clean of brake fluid.
INSTALLATION
1. Apply PBC (Poly Butyl Cuprysil) grease or silicone-based
grease between pad retainer and pad.
2. Install pad retainers and pad assemblies to torque member.
CAUTION:
Inner pad and outer pad have pad-return mechanism on
upper side of pad retainer. When installing pad to torque
member, be sure to install pad return lever to pad wear sen-
sor securely.
3. Install cylinder body to torque member.
CAUTION:
When replacing pads with new ones, press in piston until
pads can be installed. In this case, carefully monitor brake fluid level in reservoir tank because
brake fluid will return to master cylinder reservoir tank.
4. Install lower sliding pin bolt, and tighten it to the specified torque. Refer to BR-27, "
Components" .
5. Secure disc rotor with wheel nuts. Depress brake pedal a few times until it gets a responsive touch.
6. Check front disc brake for drag.
7. Install tires to vehicle.

Removal and Installation of Brake Pad (With Brembo Calipers)NFS0000W
REMOVAL
1. Remove tires from vehicle with a power tool.
2. Remove the clip from the pad pin.
3. Remove the pad pin while holding down the cross spring, then

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.
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:
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.
