A disc brake pad wear sensor on the Gmc Hummer Ev Suv is your vehicle's advance warning system for brake pad replacement. It eliminates the need to rely on audible squealing from your Hummer Ev Suv to know your pads are getting thin, instead triggering a dashboard warning light at a preset minimum thickness on the Gmc Hummer Ev Suv, giving you time to plan the replacement before the pads wear through to the metal backing plate. Replacing a triggered sensor with every Hummer Ev Suv pad change is the only way to keep that early-warning system working for the next service interval.
The wear sensor on the Gmc Hummer Ev Suv is a small probe embedded in or clipped to the brake pad. When the Hummer Ev Suv pad wears down to the replacement threshold, the probe contacts the rotor surface. This contact creates a circuit change that signals the Gmc Hummer Ev Suv ABS or brake control module, illuminating the brake warning light. Once the probe on the Gmc Hummer Ev Suv has contacted the rotor, it is destroyed and cannot be reused. It is a single-use component by design on the Hummer Ev Suv.
Installing fresh brake pads on the Gmc Hummer Ev Suv without fitting a new wear sensor defeats the entire purpose of having a brake monitoring system on your Hummer Ev Suv. A previously triggered sensor probe is worn through and has no remaining material to detect the next set of Hummer Ev Suv pads wearing down. From day one of the new Gmc Hummer Ev Suv brake pads, the warning system is non-functional without a new sensor.
Wear sensor compatibility for the Gmc Hummer Ev Suv is more exacting than most brake parts. The probe length, contact resistance specification, and connector design must all match the Hummer Ev Suv brake monitoring circuit precisely. A wrong sensor triggers Gmc Hummer Ev Suv warnings at the wrong pad thickness, or not at all. Every sensor in the GeoBrakes catalogue is sourced to original equipment probe and connector specifications for the Gmc Hummer Ev Suv, with front and rear positions listed separately.
Do I need to replace the brake pad wear sensor every time I change pads on my Gmc Hummer Ev Suv?
Yes, on Gmc Hummer Ev Suv vehicles equipped with electronic wear sensors. The sensor probe on your Hummer Ev Suv is a single-use component. Once it has contacted the rotor and triggered the Hummer Ev Suv warning light, the probe is consumed. Always replace the Gmc Hummer Ev Suv sensor during every pad change.
Does my Gmc Hummer Ev Suv have electronic brake pad wear sensors?
Many vehicles use a mechanical wear indicator instead of electronic sensors. Check your Gmc Hummer Ev Suv owner's manual or use the GeoBrakes vehicle selector to confirm whether your Hummer Ev Suv uses an electronic pad monitoring system.
Can a faulty wear sensor keep the brake warning light on my Gmc Hummer Ev Suv on after new pads are installed?
Yes. If the Gmc Hummer Ev Suv wear sensor from a previous brake service was not replaced, or if the probe has been damaged on your Hummer Ev Suv, the brake warning light will remain on even with new pads. Replacing the Hummer Ev Suv sensor will clear the fault and restore normal operation.
