NOTE:
  1. Before starting the work, make sure that the ignition switch is OFF and depress the brake pedal more than 40 times.
  2. When a pressure in power supply system is released, reaction force becomes heavy and stroke becomes shorter.
  • As high pressure is applied to the brake actuator No. 1 tube, never deform it.
  • Until the work is over, do not turn the ignition switch ON.
  1. Draw out fluid with syringe.
    NOTE: Do not let brake fluid remain on a painted surface. Wash it off immediately.
