Your modern, high-tech Mercury Sable Brakes are far superior to bicycle brakes - and even those of cars of twenty years ago. However, they essentially work the same way. When you step of the brake pedal, it activates a series of cylinders that contain pistons that pump a special hydraulic fluid through the system.

This fluid activates pairs of calipers that squeeze metal disks, known as brake rotors. By slowing these discs (which are actually part of your car's wheels), the vehicle is brought to a stop.

Friction is provided by special surfaces applied to the rotors, which are called brake pads. These are typically made of some mixture of resins and steel wool. The best quality brake pads also contain Kevlar, which is used in bullet-proof body armor. The good thing about brake problems is that they are easy to diagnose, and usually become apparent long before they become a serious safety issue. For example, whining or squealing brakes are telling you that the brake pads are wearing out. Although your Mercury Sable Brakes will continue to function quite well for a few thousand miles after the squealing begins, if this is not addressed, eventually the pads will wear through, causing some major damage to both the calipers and the rotors. A "soft" or "spongy" brake pedal, on the other hand indicates low brake fluid levels. This may be remedied by adding brake fluid to the master cylinder, but it this doesn't solve your problem, chances are you have a leak or a defective brake cylinder.In either case, you'll get the best deals parts for your Mercury Sable Brakes, because we meet or beat all competitor's prices.
