Inspection

Inspect Front Brake Disc Thickness

  1. Inspect the brake pads for wear and discoloration.

  2. Inspect the brake disc for damage and cracks.

  3. Remove all rust and contamination from the surface, then measure the disc thickness at 8 points at equal distances (5 mm) from the outer edge of the brake disc.

    Front brake disc thickness

    - Standard: 22 mm (0.8661 in)

    - Maximum service limit: 20.4 mm (0.8031 in)

    - Deviation: Less than 0.005 mm (0.0002 in.)

  4. If wear exceeds the service limit, replace the discs and pads as a set, left and right of the vehicle.

Front Brake Pad Inspection

  1. Check pad wear. Measure the pad thickness and replace it if it is less than the specified value.

    Pad Thickness

    Standard value: 11.0 mm (0.4331 in)

    Maximum service limit: 2.0 mm (0.0787 in)

  2. Make sure grease is applied to the sliding contact points, and check the pad and backing plate for damage.

Inspect Front Brake Disc Runout

  1. Position a dial indicator approximately 5 mm (0.2 in) from the outer edge of the brake disc and measure disc runout.

    Brake disc runout Limit: 0.04 mm (0.00157 in.) or less (new)

  2. If brake disc runout exceeds the limit, replace the disc, then measure the runout again.

  3. If the runout does not exceed the limit, install the brake disc rotated 180°, then check the brake disc runout again.

  4. If runout cannot be corrected by changing the position of the brake disc, replace the brake disc.

Installation

  1. Install in the reverse order of removal.

  2. Use SST (09581-11000) when installing the brake caliper assembly.

  3. After installation, bleed the brake system.
