Frequently Asked Questions
How do mechanical pad wear sensors work?
Mechanical sensors are thin metal tabs attached to the pad that contact the rotor when the friction material wears thin, producing a squeal to alert you it’s time to replace pads. They’re simple and reliable if installed correctly.
Are electronic wear sensors better than mechanical ones?
Electronic sensors give earlier, dashboard-style warnings and are more precise, but they require wiring and compatible vehicle circuits. Mechanical sensors are lower cost and effective when you replace pads at regular intervals.
Should I replace rotors when I change pads?
Replacing rotors at the same time prevents uneven wear and reduces noise. If rotors meet thickness and runout specs and show little scoring, you can resurface them, but many kits here include new rotors to simplify maintenance and ensure proper sensor clearance.
