Front Disc Rotor: Installation

WARNING: This page is about a different car, the 2022 Subaru WRX. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Before installation, remove mud and foreign matter from the disc brake assembly front.

Check the brake disc front. Ref. to BRAKE>FRONT DISC ROTOR>INSPECTION .
Press back the piston disc brake with a disc brake piston tool.
CAUTION:
When pressing back the piston disc brake, the clearance between pad disc brake and brake disc 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.
