Whether you need brake-fluid changes, brake pad changes, or a complete brake system including master cylinder, our team of technicians is here to meet all of your automotive repair needs. Your brakes work through the use of friction. The calipers contain the brake pads which squeeze down on the spinning rotor (which is attached to your wheel) when the brake pedal is pressed. The friction caused by the brakes pads pushing against the rotor is what brings your car to a stop. The brake pads on your car are designed to wear out over time. They are made from a softer material than the hard metal rotor that they press on. These days many discount brake shops offer cheap brake specials by manufacturing their own cheap brake pad. These pads are much harder than the original pads recommended by the manufacturer of your car so the pads will outlast your brakes hardware. The offer you a lifetime warranty on the pad but they don't tell you that you will go through many sets of expensive rotors and calipers. Maintaining your car's brakes is an important part of keeping your automobile safe and running at its best. Our team at Auto Diagnostic Specialists is here to offer you excellent service and a the best warranty in town on your car's brake repairs.
