300 MAINTAINING YOUR VEHICLE Brake Master Cylinder The fluid level in the master cylinder should be checked when performing under hood services, or immediately if the brake system warning lamp is on. Be sure to clean the top of the master cylinder area before removing the cap. If necessary, add fluid to bring the fluid level up to the requirements described on the brake fluid reservoir. Fluid level can be expected to fall as the brake pads wear. Brake fluid level should be checked when pads are replaced. However, low fluid level may be caused by a leak and a checkup may be needed. NOTE: If your vehicle is equipped with a Manual Transaxle , the Brake Fluid Reservoir supplies fluid to both the Brake System and the Clutch Release System. The two systems are separated in the reservoir and a leak in one system will not affect the other system. The Manual Transaxle Clutch Release System should not require fluid replacement during the life of the vehicle. If the Brake Fluid Reservoir is low, and the brake system does not indicate any leaks or other problems, it may be a result of a leak in the Hydraulic Clutch Release System. See your local authorized dealer for service. Use only manufacturers recommended brake fluid, refer to Fluids, Lubricants and Genuine Parts for correct fluid type. WARNING! Use of a brake fluid that may have a lower initial boiling point or unidentified as to specification, may result in sudden brake failure during hard prolonged braking. You could have an accident. CAUTION! Use of improper brake fluids will affect overall clutch system performance. Improper brake fluids may damage the clutch system resulting in loss of clutch function and the ability to shift the transaxle.
