Be sure to have your brakes maintenanced on a regular basis. Your brake system is comprised of several components including brake lines, master cylinder, slave cylinders, brake pads, rotors, calipers, and drums. All of these need regular maintenance to ensure that you vehicle will function properly on the road. If your pads are worn, have them replaced.
Check your brake fluid level frequently. The brake warning system has been required standard equipment since 1970. It monitors the differences in pressure in the brake lines of the two hydraulic sub-systems of the master cylinder and alerts the driver with a light when an imbalance occurs.
