FLUID RECOMMENDATIONS

WARNING
BRAKE FLUID EATS PAINT. Take great care not to splash or spill brake fluid on painted surfaces. Should
you spill a small amount on the car's finish, don't panic, just flush the area with plenty of water.
When adding fluid to the system ONLY use fresh DOT 3 brake fluid from a sealed container. DOT 3 brake
fluid will absorb moisture when it is exposed to the atmosphere, which will lower its boiling point. A
container that has been opened once, closed and placed on a shelf will allow enough moisture to enter over
time to contaminate the fluid within. If your brake fluid is contaminated with water, you could boil the brake
fluid under hard braking and loose all/some of the brake system. Don't take the risk, buy fresh brake fluid
whenever you must add to the system.
LEVEL CHECK
Brake fluid level and condition is a safety related item and it should be checked ANY TIME the hood is
opened. Your vehicle should not use brake fluid rapidly (unless there is a leak in the system), but the level
should drop slowly in relation to brake pad wear.
