Description:Anti lock braking system speed sensors magnetically read the rotational speed of each wheel, which is fed back to the vehicle’s electronic control unit. When a wheel is starting to lock up and/or skid, the abs system intervenes to gradually release and reapply the brake many times per second to help ensure maximum braking efficiency and directional control can be maintained. Without abs, a wheel will automatically lock up in slippery and/or gravel-like conditions, as well as potentially experience a loss of directional control and vehicle stability.One of the most common indications of a faulty abs sensor would include the lighting up of the abs light or the traction control light in the dashboard of the vehicle. If both your abs light and brake system light come on, this is an emergency and you need to stop driving right away and check your entire brake system.Specifications:Package included: 1pc rear abs sensorMaterial: metal, rubberUse position: rear left or rightBuilt to strict quality control standards. 100% tested prior to leaving the factoryWarranty:This is an aftermarket part and covered by our 12 months unlimited mileage warranty.
