Several months ago I had a local shop replace the rear brake pads on my wife's car. Since then, the few times I've driven it, I've noticed some shimmy when slowing down (braking). It wasn't shaking the steering wheel like warped front rotors can do.
Stupid me, I don't think "brakes" since the pads are fine and I don't know of any stress that might have caused rotor warpage. I'm thinking maybe the tires need balancing or something.
Recently, a friend suggested that overtorquing the lug nuts can warp rotors (anyone heard this?), and that rotating the tires could provide some insight into tire balancing as a possible cause. It's about time to rotate the tires anyway, so I decide to do that yesterday.
Well, turns out I can't break loose the rear lug nuts! You'd think a place called "Brake King" would know how to torque lug nuts. Spec torque is only 65 ft-lbs, and these puppies don't wanna break loose with a half-inch drive breaker bar. Way, way too tight. I didn't force the issue - I'll take it back in to the shop and talk to them.
On the one hand, the evidence suggests to me that their overtorquing has caused the problem. On the other hand, it's been about 3.5 months since they did the work, so I expect resistance on their part.
Any experience to relate or advice to offer?
Thanks...
