Front Brake Master Cylinder - Assembly

Warning Brakes - Mineral based grease

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.

Warning - Brakes - Clean and lubricate internal brake components with DOT 4 fluid

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.
  1. Lubricate the piston and cylinder with new, clean brake fluid.
    2. warning
    Ensure that the piston and piston seal are fitted facing the same way as noted during removal. A dangerous riding condition leading to loss of motorcycle control and an accident could result from incorrect assembly of the master cylinder.
  2. Fit the new piston set into the master cylinder and retain with a new circlip.
  3. Refit the master cylinder boot.
