So I go to get my wheels changed and balanced and I leave with the driver side rim heating up unnaturally even after driving just a few miles.
The car stops unusually quickly. It's quite clear that the brake pads are clutching/seizing on the rotor—even when I'm not pressing the brakes.
My question is: What could have gone wrong? I'm suspecting they messed something up. Would, for example, tightening the bolts far too much lead to pushing the brake pads against the rotor? I see no (brake fluid) leakage, nor any other symptoms, except that they also did a lousy job at balancing the wheels: The steering wheel wobbles starting from 30mph.
It's disappointing that no one recommended not driving the car, or driving it minimally, until the problem is fixed.
I now know that if one continues to drive the car—even for just 50km, the rotor in question will heat up to the point where it will no longer be guaranteed that it is perfectly planar. A simple job of replacing the brake pads and resetting the fluid becomes an expensive replacement of the rotor, the calipers, and the tube leading to the calipers.
