• Use of any brake fluid other than the specified brake fluid will cause permanent damage to brake components and will render the brakes inoperative. Failure to follow these instructions may result in personal injury.

Note

• Inspect the fluid level in the master cylinder before the inspection. If the fluid level is below the MAX line, add specified brake fluid.
