Brakes Brake Fluid The brake master cylinder and, on manual transmission vehicles, the clutch hydraulic system use the same reservoir. The reservoir is filled with DOT-3 brake fluid. It is not a good idea to top off the brake/clutch fluid. Adding fluid will not correct a leak. If fluid is added when the brake 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. {CAUTION: If your vehicle has too much brake fluid, it can spill on the engine. The fluid will burn if the engine is hot enough. You or others could be burned, and your vehicle could be damaged. Add brake fluid only when work is done on the brake and/or clutch hydraulic system. When the brake fluid falls to a low level, the brake warning light will come on. See Brake System Warning Light on page 3-33. See Engine Compartment Overview on page 5-12 for the location of the reservoir. There are only two reasons why the brake fluid level in the reservoir might go down. The first is that the brake fluid goes down to an acceptable level during normal brake lining wear. When new linings are put in, the fluid level goes back up. The other reason is that fluid is leaking out of the brake and/or clutch hydraulic system. If it is, you should have the brake and/or clutch hydraulic system fixed, since a leak means that sooner or later the brakes and/or clutch will not work well. 5-30
