The brake pads of the braking system are considered as among the most battered devices of a vehicle. These pads receive the brunt of the frictional impact that stops a vehicle from running. Thus, the brake pad usually thins down due to the force it takes in. The crucial factor in such a situation is in being able to monitor if the pad's thinness is still tolerable or already within dangerous proportions. That is why the brake pad is equipped with a brake pad sensor.
As its name implies, the brake pad sensor monitors the status of the fragile brake pads. If the brake pad sensor detects that the pads are already damaged and have thinned beyond the allowable width, it readily alerts the car owner through an indicator at the dashboard area. With properly functioning brake pad sensors, car owners no longer need to inspect the brake pads from time to time. This ensures that the brake system is well-conditioned even with minimal checking. Moreover, the brake pad sensor has a couple of security duties for the braking system. This includes the simple yet valuable role of activating the brake lights of the vehicle, as well as the counting of the wheel rotations for the accurate timing of the brake warning light. This U-shaped copper wire usually comes in pairs, namely the front sensor and the rear sensor. The front brake pad sensor is usually positioned at the left side of the wheel assembly, whereas the rear sensor stands guard at the assembly's right area.
With its vital monitoring responsibilities, car owners are advised to know the signs of a faulty brake pad sensor to avoid using a car with a possibly dangerous braking mechanism. The symptoms of a defective sensor include annoying and shrieking squeals during brake application, as well as a mistimed brake light signaling. When these conditions arise, it is imperative that the brake pad sensor be immediately set for professional check-up. If deemed faulty, immediate replacement is necessary. This key security feature, when properly functioning, keeps passengers protected from and forewarned about impending brake problems.
