My front passenger caliper has seized up again today for the third time in two years. I noticed some increasing vibration in the steering wheel and a smell of burn while driving and pulled over to inspect the front end of the car. The right front caliper was burning hot and smelled like overheated brakes. The car had been driven for about 30 minutes in the city and light highway driving. I started to notice the increasing vibration on the highway. All failures happened in wet weather. The two previous failures were repaired with new calipers, rotors and pads. Could this failure be caused by something else than a bad caliper? These failures always seem to happen at 11 months interval and coincide with the arrival of the rainy season of the pacific northwest.
