Install the pad clip.
Press back the piston with a disc brake piston tool as needed.
CAUTION: When pressing back the piston, the clearance between pad and disc rotor becomes large, which makes the brake pedal effort softer.
After the installation of front wheel, be sure to perform the adjustment of the clearance and the pedal effort by depressing the brake pedal several times.
Install the brake pad to the support - front disc brake.
CAUTION:
- Be sure to install so that the pad return spring faces the input side of the direction of brake rotor rotation, as shown in the figure.
- Correctly install the pad return spring to the supporting surface of the pad clip as shown in the figure.
- If the pad return spring is deformed or damaged, replace the brake pad with a new part.
