272 MAINTAINING YOUR VEHICLE 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. 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. WARNING! Overfilling the brake fluid reservoir can result in spilling brake fluid on hot engine parts and the brake fluid catching fire. Use only brake fluid that has been in a tightly closed container to avoid contamination from foreign matter. Do not allow petroleum based fluid to contaminate the brake fluid as seal damage will result! Use only manufacturers recommended brake fluid, refer to Recommended Fluids, Lubricants and Genuine Parts for correct fluid type.
