I drove my jeep home this afternoon after work and it seemed to be pulling one way and when i braked the other way, really odd, drove fine this morning.. I get home and get out and something smells very hot and burnt, near front drivers area. So i open the hood and check exhaust and in doing so i could smell the burnt really hot smell again closer to the wheel, so i tough the wheel in the center and WOW its hot.. My guess is caliper was stuck, but im not sure if there could be a axle bearing issue?? I then drove the jeep to eat and after we parked i touched it and it was still warm/hot, but no burnt smell.. then we drove it back home and it wasnt hot at all and no pulling either, what gives?? Am I on track with a brake, caliper issue, or could there be a axle bearing issue? both?? what should i look for, I know the front brake pads still have plenty of life left??? thoughts, ideas, ????
