wheel gets hot

[mannymac]

My driver side wheel gets really hot. I hit a pothole the other day and felt the car start to vibrate. When I got home, I checked to see if the wheel got bent but was ok. As I reached to touch the wheel, I felt a lot of heat coming from the wheel. Sure enough, the wheel was hot. I ended up replacing the hub assembly, thinking that was the problem. When I test drove the car, I still felt the vibration. I feel the vibration only when I get to 50mph. When i got to my destination, I touched the wheel again and it was hot. What can be the problem? What are the odds of me getting a bad hub assembly? I also thought that the caliper might be getting stuck. But if the caliper was getting stuck, would that cause me to feel a vibration at 50mph? I checked the degrees on how hot everything was with my heat gun. The wheel was at 130, the caliper was at 220, and the rotor was at 350!!! When i checked the passenger side, the wheel and caliper were 67, and the rotor was 85. Any help would be appreciated.

Defintely sounds like a caliper. Take it off and check it out. That can cause a vibration. Start with the caliper and get back to us. Then take your tire and rim to a shop to have it balanced. Also have them road force the tire to check for a broken belt or something of that nature. They can also do a rim runout test to see if the rim is bent.

There isn't anything wrong with your caliper. The odd of you hitting a pothole and it damaging you rotor/caliper are next to none. The heat is normal. I've taken off many wheels where you couldn't hold the lug nuts. Here is a quote from an article on brakes.

"If you multiply horsepower by the proper conversion factor, you discover that one horsepower generates 42.4 BTUs of heat per minute. If stopping a 4,000 lb. vehicle from 60 mph in roughly 150 feet requires 600 horsepower of force, it is the equivalent of 25,440 BTUs of heat, which is enough heat to raise 15 gallons of water from zero degrees to boiling! No wonder the brakes get so hot" You can check out the entire article here Disc Brake Rotor Design Science

To answer your vibration issue, more than likely you either bent the rim or broke a belt. Take it to a shop and have the wheel/tire checked out.

Take off your rotor and have it checked or do it yourself if you have a dail guage and stand. Something is sticking or rubbing with your brakes.

I pushed my brake caliper in with a clamp a few times on my 1g (had to use a hammer first it was stuck so tight), and now it works fine; not like I wouldn't recommend just getting a different one though.
