Vehicle Care 10-21 Brake Fluid since a leak means that sooner or later the brakes will not work well. Do not top off the brake/clutch fluid. Adding fluid does not correct a leak. If fluid is added when the linings are worn, there will be too much fluid when new brake linings are installed. Add or remove fluid, as necessary, only when work is done on the brake/clutch hydraulic system. Checking Brake Fluid The brake/clutch fluid can be checked without taking off the cap by looking at the brake/clutch fluid reservoir. The fluid level should be above MIN. If it is not, have the brake/ clutch hydraulic system checked to see if there is a leak. After work is done on the brake/ clutch hydraulic system, make sure the level is above MIN but not over the MAX mark. When the brake/clutch fluid falls to a low level, the brake warning light comes on. See Brake System Warning Light on page 5￿15. What to Add Use only new DOT 3 brake fluid from a sealed container. See Recommended Fluids and Lubricants on page 11￿12. The brake/clutch master cylinder reservoir is filled with DOT 3 brake fluid as indicated on the reservoir cap.

You or others could be burned, and the vehicle could be damaged. Add brake fluid only when work is done on the brake/clutch hydraulic system.

A fluid leak in the brake/clutch hydraulic system can also cause a low fluid level. Have the brake/ clutch hydraulic system fixed, .
