10-28 Vehicle Care Refer to the Maintenance Schedule to determine when to check the brake fluid. See Scheduled Maintenance on page 11‑2. After work is done on the brake hydraulic system, make sure the level is above the MIN but not over the MAX mark. What to Add Use only new DOT 3 brake fluid from a sealed container. See Recommended Fluids and Lubricants on page 11‑7. Always clean the brake fluid reservoir cap and the area around the cap before removing it. This helps keep dirt from entering the reservoir. Do not top off the brake 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 brake fluid, as necessary, only when work is done on the brake hydraulic system. Checking Brake Fluid Check brake fluid by looking at the brake fluid reservoir. See Engine Compartment Overview on page 10‑6. { WARNING If too much brake fluid is added, it can spill on the engine and burn, if the engine is hot enough. You or others could be burned, and the vehicle could be damaged. Add brake fluid only when work is done on the brake hydraulic system. See "Checking Brake Fluid" in this section. When the brake fluid falls to a low level, the brake warning light comes on. See Brake System Warning Light on page 5‑23. { WARNING With the wrong kind of fluid in the brake hydraulic system, the brakes might not work well. This could cause a crash. Always use the proper brake fluid. The fluid level should be above MIN. If it is not, have the brake hydraulic system checked to see if there is a leak.
