Although they have a much tougher job to do, your car's brakes are not a whole lot different from those on a bicycle. In both cases, a pair of calipers squeeze a disc, producing friction that actually stops the vehicle. The difference is that a bicycle's brakes are worked by the hands, whereas an automobile weighing anywhere from 1-3 tons requires a special hydraulic system to bring the automobile to a stop.

In the case of a bicycle, the calipers have a hard rubber surface that squeeze the metal rims. Since automotive calipers are made of metal, your Mercury Grand Marquis Brake Pads guard the bare metal of the rims by providing a surface for those calipers to grab onto.

This surface is typically made from some mixture of steel wool, resin and - in the case of higher quality brake pads - Kevlar (the substance used in bullet-proof vests). You can extend the life of your brake pads by developing good driving habits - avoid sudden, hard stops and try not to "ride" the brakes when going down steep hills. Shift into low gear and let engine compression slow the vehicle. And don't race to the intersection when the light is red, then slam on the brakes. You'll only put more wear on your brake components, and meanwhile, the light won't turn green any sooner. That said, there will come a day when your brakes will start making an annoying squealing or whining sound when you step on the pedal. It's what happens when your Mercury Grand Marquis Brake Pads are ready for retirement.When that time comes, get the best discount price on genuine Mercury Grand Marquis Brake Pads right here!
