The brakes will get hot and lock up?

Thank you for responding! For the most part it happens the more you drive but sometimes you can just go down the road. Also, it doesn't do it as badly when it's cold out. Yes, I have adjusted the push and am still getting the same result. Also, it's not always the same wheel locking up or getting hot, sometimes it's the front brakes or and sometimes it's one of the back ones. Not sure how hot it is too hot for the wheel to get. It varies from 90 to 220. I read on another post earlier about a park brake causing rear brake problems. My park brake wire is a little frayed. Could that keep it from releasing all the way and causing my brakes to act crazy? I know this brake problem is about drive me crazy, lol.

Okay, we went and got a new parking brake cable, and my son and boyfriend are installing it now. I will have my son or boyfriend drive it and check the wheels tomorrow, and I will let you know.

Okay, so they replaced the parking brake cable and drove it. They said that it drove better and didn't feel like they were dragging but when they got back home the back passenger brake was 210 and all others were 80 to 90 degrees. My boyfriend drove it to work (about 15 miles) and it did fine, but on the way home the truck drove fine but the driver's side front was 110 passenger was 80 drivers rear was 82 and passenger rear was 220. They jacked the front wheel, and it would not turn until they bled the brakes which the bleeder did not want to open. The rear tire would not turn either until they bled it. Again, the bleeder did not want to open. The only thing I have not replaced as of yet is the module control and the ABS hydraulic unit.

With that being said the front may be a caliper problem but what would keep the back locking up and overheating because those are drum brakes?

We have done all that. They blocked off the back brakes last night, then drove around without any problems until they pulled in the driveway. He turned off the truck and cranked it back up and the ABS and brake light both came back on. Both rear brakes were 70 degrees, and the front were 130 degrees. But now the brakes are spongy and won't get hard.

So, if the ABS hydraulic unit/valve on the rear frame is bad what would happen? Or the ABS module behind the glove compart? Is there a way to test either of these?
