Front Brake Caliper - Assembly
- If all components are serviceable, obtain a piston seal kit and reassemble the caliper as follows:
- Ensure all components are clean, then fit the new seals to their grooves in the caliper bores.
- Lubricate the fluid seals, caliper bore and the outside of the pistons with clean DOT 4 brake fluid.
- Ease the pistons squarely back into the bores, taking care not to displace the seals.
- Lubricate the mounting bracket pins with a suitable silicone based brake grease then reassemble the bracket and caliper. Ensure the pin gaiters are correctly located on both the bracket and caliper.

warning
Always renew caliper seals after removal of the pistons. An effective hydraulic seal can only be made if new seals are fitted.A dangerous riding condition leading to loss of motorcycle control and an accident could result if this warning is ignored.
warning
Before installation, all internal brake components should be cleaned and lubricated with clean new DOT 4 brake fluid.Never use solvents, petrol (gasoline), engine oil, or any other petroleum distillate on internal brake components as this will cause deterioration of the hydraulic seals in the calipers and master cylinders.A dangerous riding condition leading to loss of motorcycle control and an accident could result if this warning is ignored.
warning
Never use mineral based grease (such as lithium or copper based grease) in any area where contact with the braking system hydraulic seals and dust seals is possible. Mineral based grease will damage the hydraulic seals and dust seals in the calipers and master cylinders. Damage caused by contact with mineral based grease may reduce braking efficiency resulting in loss of motorcycle control and an accident.
