The brake master cylinder reservoir is filled with DOT-3 brake fluid. See Engine Compartment Overview 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 hydraulic system. If it is, you should have the brake hydraulic system fixed, since a leak means that sooner or later the brakes will not work well.
So, it is not a good idea to top off the brake fluid. Adding brake fluid will not correct a leak. If you add fluid when the linings are worn, there will be too much fluid when you get new brake linings. Add or remove brake fluid, as necessary, only when work is done on the brake hydraulic system.
Caution: 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.
Refer to the Maintenance Schedule to determine when to check the brake fluid. See Scheduled Maintenance .
The brake fluid can be checked without taking off the brake fluid reservoir cap by looking at the brake fluid reservoir.
The fluid level should be above the MIN (minimum) mark. If it is not have the brake system checked to see if there is a leak.
After work is done on the brake hydraulic system, make sure the level is above the MIN mark but not over the MAX (maximum) mark.
When you do need brake fluid, use only DOT-3 brake fluid. Use new brake fluid from a sealed container only. See Recommended Fluids and Lubricants .
Always clean the brake fluid reservoir cap and the area around the cap before removing it. This helps keep dirt from entering the reservoir.
Caution: 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.
Notice:
• Using the wrong fluid can badly damage brake hydraulic system parts. For
example, just a few drops of mineral-based oil, such as engine oil, in the brake hydraulic
system can damage brake hydraulic system parts so badly that they will have to be
replaced. Do not let someone put in the wrong kind of fluid. • If brake fluid is spilled on the vehicle's painted surfaces, the paint
finish can be damaged. Be careful not to spill brake fluid on the vehicle.
If you do, wash it off immediately. See

Your vehicle has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound can come and go or be heard all the time your vehicle is moving, except when you are pushing on the brake pedal firmly.
Caution: The brake wear warning sound means that soon the brakes will not work well. That could lead to an accident. When the brake wear warning sound is heard, have the vehicle serviced.
Notice: Continuing to drive with worn-out brake pads could result in costly brake repair.
Some driving conditions or climates can cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with the brakes.
Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly tighten wheel nuts in the proper sequence to torque specifications in Capacities and Specifications .
Rear drum brakes do not have wear indicators, but if you ever hear a rear brake rubbing noise, have the rear brake linings inspected immediately. Also, the rear brake drums should be removed and inspected each time the tires are removed for rotation or changing. When you have the front brake pads replaced, have the rear brakes inspected, too.
Brake linings should always be replaced as complete axle sets.
See your dealer/retailer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign that brake service might be required.
Every time you make a brake stop, the brakes adjust for wear.
The braking system on a vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Your vehicle was designed and tested with top-quality brake parts. When you replace parts of the braking system -- for example, when the brake linings wear down and you need new ones put in -- be sure you get new approved replacement parts. If you do not, the brakes might not work properly. For example, if someone puts in brake linings that are wrong for your vehicle, the balance between the front and rear brakes can change -- for the worse. The braking performance you have come to expect can change in many other ways if someone puts in the wrong replacement brake parts.
