Fitting notes
- Bleed screws must be at the top.
- The disc must pass the smaller piston first (differential bore calipers).
- AP Racing say brake parts should only be fitted by people experienced in fitting disc brake systems.
- AP Racing: calipers that regularly run at up to 180°C should be re-sealed every other event; from 180°C to 220°C and above, re-seal as soon as possible.
