Replacement point = 2.0 mm

Preparations
Remove wheel.

Removal of brake pads







- Knock out split pins using a 3 mm (0.12 inches) mandrel.
- Remove retaining spring.







- Remove brake pads and shims. Use extractor 999 2917 if brake pads are difficult to remove.

Cleaning and checking
- Clean brake pad contact surfaces in brake caliper and on caliper mounting.
- Check piston dirt guard.
- If dirt guard looks worn, replace it as a precautionary measure.
- If dirt guard is damaged, overhaul brake caliper.

NOTE: If dirt guard is damaged, dirt may have penetrated into the cylinder and so the brake caliper needs to be overhauled.







- Check brake disc friction surface.
- If brake disc shows signs of being skew, check its lateral run-out.
- If brake disc shows signs of major wear, variations in thickness etc., replace it.

NOTE: Disc thickness = replacement point = 23.0 mm (0.9 inches). Minimum recommended disc thickness when installing new brake pads = 23.8 mm (0.94 inches).

Installing wheel







- Make sure that brake discs and rim contact surfaces are clean.
- Grease hub center rim guide with anti-rust agent 116 1038-3.
- Install wheel.
- Tighten bolts handtight. Then tighten them crosswise to 110 Nm (80 ft.lb). If using an air gun, use torque socket 115 8147.

NOTE: Tightening bolts crosswise to a specific torque setting is important in preventing stresses in the brake disc.
