How do I adapt a factory pad wear sensor to a StopTech big brake kit?
A pad wear sensor is designed to detect when the brake pads are near the end of their life. The warning depth is set by the manufacturer at about 2 mm above the absolute limit of pad wear. There are 2 common types of sensors, mechanical and electronic. Mechanical sensors consist of a soft, metal tab attached to the pad that rubs on the rotor, creating an audible squeal when the pad needs replacement. Electronic sensors trigger a warning light or text message on the instrument panel. Not all cars have pad electronic or mechanical wear sensing capabilities. If an aftermarket pad has wear sensing capability, it is a copy of the OEM design. There is not any reasonable way to upgrade a car that does not have this feature or to convert the metal tab type to the electronic type. With electronic pad sensors, when the pad wears to its warning thickness, the rotor rubs through the sensors insulating cover, either creating a short circuit or breaking a thin wire and opening a circuit, depending o
