< PRECAUTION >
PRECAUTIONS
• Tighten the brake tube flare nut to the specified torque with
crowfoot (A) and torque wrench (B).
• Always confirm the specified ti ghtening torque when install-
ing the brake pipes.
• Turn the ignition switch OFF and disconnect the ABS actuator
and electric unit (control unit) connector or the battery nega-
tive terminal before performing the work.
• Check that no brake fluid leakage is present after replacing the parts.
• Burnish the brake contact surf aces after refinishing or replac-
ing rotors, after replacing pads, or if a soft pedal occurs at
very low mileage.
- Front brake: refer to BR-16, "Brake Burnishing"
.
- Rear brake: refer to BR-17, "Brake Burnishing"

FRONT DISC BRAKE
BRAKE PAD
BRAKE PAD : InspectionINFOID:0000000009463687
PA D W E A R
Check brake pad thickness from an inspection hole on caliper body.
Check using a scale if necessary.
DISC ROTOR
DISC ROTOR : InspectionINFOID:0000000009463688
APPEARANCE
Check surface of disc rotor for uneven wear, cracks or damage. Replace if any abnormal conditions exist.
RUNOUT
1. Check the wheel bearing axial end play before the inspection. Refer to FAX-6, "Inspection".
2. Secure the disc rotor to the wheel hub and bearing assembly with wheel nuts at two wheel nut locations.
3. Inspect the runout with a dial gauge, measured at 10 mm (0.39 in) inside the disc edge.
4. Find the installation position with a minimum runout by shifting the disc rotor-to-wheel hub and bearing assembly installation
position by one hole at a time if the runout exceeds the limit
value.
5. Refinish the disc rotor if the runout is outside the limit even after performing the above operation. When refinishing, use Tool.
THICKNESS
Check the thickness of the disc rotor using a micrometer. Replace
the disc rotor if the thick ness is below the wear limit.
Wear limit thickness : Refer to
BR-49, "Front Disc
Brake".

APPERANCE
Check surface of disc rotor for uneven wear, cracks or damage. Replace if any abnormal conditions exist.
RUNOUT
1. Check the wheel bearing axial end play before the inspection. Refer to RAX-8, "Wheel Hub Bearing".
2. Secure the disc rotor to the wheel hub and bearing assembly with wheel nuts at two wheel nut locations.
