1987473525 Bosch Wear Sensor F.Brake Pad

The Front Brake Pad Wear Sensor from Bosch (MPN: 1987473525) is sourced from Germany and has supplier-listed dimensions of 9 x 129 x 169 mm. It is typically used within the Service Parts > Major Service > Brake Pads category of automotive replacement parts. Dimensions are provided by the supplier and may include packaging dimensions. Brake pads are friction surfaces actuated by caliper pistons to create braking force against a vehicle’s rotors. Positioned within the brake caliper assembly at each wheel, they convert kinetic energy into thermal energy through repeated contact. Pad composition varies – typically ceramic, organic, or metallic – influencing friction coefficient, wear rate, and noise characteristics. Backing plates provide structural support and mounting features, while friction material thickness dictates service life. Effective braking relies on consistent pad-to-rotor contact and appropriate material selection for vehicle weight and usage.
