NOTE:
  • If the master cylinder is disassembled or reservoir tank is empty, bleed the master cylinder.
  • During the bleeding operation, keep the brake reservoir tank filled with brake fluid to eliminate entry of air.
  • The brake pedal operating must be very slow.
  • For convenience and safety, two people should do the work.

  2. Disconnect the brake line at primary and secondary sides.
  3. Put a plastic bag cover on master cylinder.
