Cadillac to Debut Electric Brake Wear Sensors on 2019 CT6
A new model year brings with it an abundance of new makes as well as updated features and tech. Cadillac is no exception. Besides adding the XT4 crossover to its lineup and introducing a second-gen rear camera mirror on certain models, the brand is also incorporating electric brake pad wear sensors. It will be GM’s first use of this technology on one of its products.
Per GM Authority, these sensors will be standard inclusions on 2019 CT6 models outfitted with the new eBoost electro-hydraulic brake booster. That means, on models equipped with either the 2.0-liter turbo I4 LSY or 4.2-liter twin-turbo V8 LTA powertrains. The automaker also plans on using them on just the rear right and front left brake pads, to reduce costs and minimize the potential noise the sensors make when the pads are wearing thin.
Electric brake pad wear sensors consist of a conductive metal loop embedded in the brake pad. The loop transmits a small current when the car is in motion. When the brake pad wears down, it exposes the metal loop so it comes into direct contact with the brake rotor. This triggers a dashboard light which alerts the driver that the brake pads need to be replaced. Some sensor designs feature two loops at different depths of the tread, enabling the vehicle’s technology to determine just how much wear the brake pad has left on it.
Electric brake pad sensor technology is common on German-made autos, but Cadillac’s inclusion of it on the CT6 is an innovative move for this American-made brand. The technology should help Cadillac owners stay safer by letting them know when it’s time for new brake pads.
