Brakes are brakes are brakes - although they can differ greatly from one make and model to another in terms of quality and stopping power, they all work pretty much the same way. When you push on the brake pedal, it activates a plunger in the master brake cylinder, which in turn causes a special hydraulic fluid to expand within the sealed brake system. Traveling through tubes called "brake lines," this fluid is able to exert considerable force.
It works pistons within the four wheel, or "slave" cylinders, which cause a pair of calipers to close around a resin and steel wool covered disk called the brake "rotor." The resin and steel wool covering is the brake "pad." It provides friction against the calipers, which actually causes the vehicle to stop. As in all brake systems, potential problems with the Mercury Grand Marquis Brakes are easily identified and diagnosed.
An annoying squealing sound indicates worn brake pads. Depending on the kind of driving you typically do, brake pads will wear sooner (if most of your driving is in the city) or later (if you drive mostly on the open highway).
Generally, all brake pads will need replacement by around 100,000 miles. "Mushy," or soft-feeling brakes that travel too far toward the floorboard indicate a different problem.
