Checking your car's brakes

Your vehicle's most critical system is its brakes. Many people never look at the master cylinder until they have brake failure. In late-model vehicles, the master cylinders are often made of semi-opaque plastic that allows inspecting the fluid level without taking off the cover, as is the case with cast-iron master cylinders. In addition to checking fluid level, look for leaks where the brake lines attach to the master cylinder and where the master cylinder bolts to the power booster. If the master cylinder is leaking at the rear, replace it. In the interest of safety, periodically get under the vehicle and inspect the rubber hoses that go to the wheels for excessive wear or cracks, replace these hoses as necessary. Finally, check brake shoes and/or caliper pads regularly. Worn pads can damage the brake rotor or drum, turning a simple maintenance job into an expensive replacement procedure.
