Caution / Notice / Hint

NOTE:
  • Move the shift lever to P and apply the parking brake before bleeding the brakes.
  • Add brake fluid to keep the level between the MIN and MAX lines of the reservoir while bleeding the brakes.
  • Do not allow brake fluid to contact any painted surface. If brake fluid leaks onto any painted surface, immediately wash it off.
  • Do not operate the brake actuator assembly while air is in the brake system or in the brake master cylinder sub-assembly. Doing so may cause air to enter the brake actuator assembly.
  • When bleeding air, select the suitable procedure according to the table below.
