Release the brake caliper and tie aside.
-
CAUTION: Brake discs must be renewed in pairs, unless one disc requires changing before 1000 miles (1600 kilometers) from new.
At 4 points around disc, measure disc thickness using a micrometer; renew disc if less than service limit or if variation is exceeded: Disc thickness, NEW 30 mm, Service limit = 27 mm. Thickness variation maximum = 0.01.
Mount a Dial Test Indicator (DTI) to and secure to inboard side of hub using caliper assembly upper bolt hole.
- Position DTI probe 5 mm in from outer edge of disc.
- Install the road wheel.
- Zero DTI and rotate road wheel one complete revolution to measure disc runout. Disc runout must not exceed 0.05 mm (0.002 in).
- If disc runout is outside limits:
- Remove the road wheel.
- Remove Allen screw securing brake disc to drive flange.
- Remove the brake disc.
- Make sure the mating surfaces of disc and drive flange are clean.
- Fit disc to flange, fit Allen screw and tighten to 16 Nm (12 lbf.ft.).
-
NOTE: Make sure the mating surfaces of disc and wheel are clean and free from paint and grease.
Install the road wheel.
- Check disc runout as detailed above.
- If runout is still outside limits, remove the road wheel.
- Remove Allen screw securing brake disc to drive flange.
- Remove the brake disc.
Using special tool (100-053) mount a Dial Test Indicator (DTI) to and secure to the backplate using the upper backplate fixing.
-
CAUTION: Make sure the DTI is positioned clear of the wheel studs.
Position the DTI probe on the outer edge of the hub face.
- If the hub runout exceeds the limit replace the hub
Refer to: SPECIFICATIONS
- Remove the DTI.
- Fit disc to flange, fit Allen screw and tighten to 16 Nm (12 lbf.ft.).
-
