Your foot pushes on the brake pedal to apply the brakes. The force of your foot is amplified by mechanical leverage and the brake booster. A piston then moves into the cylinder and squeezes the hydraulic fluid out of the end. Hydraulic fluid runs through the brake lines and hoses to transmit pressure equally to all four brakes. The force creates friction between the brake pads and brake rotors to stop your vehicle. Over time, this causes the brake pad to wear down. When the brake pad is thin, it will cause squeaking. If the brakes are grinding, the rotors may be pitted or rusted. Call us today to schedule an appointment to have your brakes checked!
