98 TJ Locking Front Brakes

I have a 1998 TJ with 200,000 clicks on it. So I had a issue with my passenger side front caliper seizing. I swapped out the caliper, rotor and pads and then had a hell of a time trying to bleed the brakes lines. At one time I could not even get fluid to pass through the line and after it was still pulling. Next I replaced the brake hose. It was still hard to get a good bleed but seemed to drive better with just a slight pull to the same side under heavy braking but then the driver side locked up. However, after it cooled off and I pulled the wheel off, the rotor was turning freely and the caliper would release easily. I replaced the hose next thinking that may be the problem. The drivers side bleed easily. Then I went back to check the passenger side . I removed the wheel and found while the rotor would turn it was tight. Then I noticed the bearings/wheel hub was shot, probably from the heat when it first seized. So, once I get the hub changed, if I still have the problem , the question is ...what else beside a stuck caliper or bad hose could cause the front brakes to size up ??
master cylinder
brake booster
proportioning valve
pb check valve
???


A Kid can never have enough sets of wheels!!!

quick questions-

Both front wheels lock/drag or just the Right front?
ABS does the ABS light come on @2seconds every start then go out?
Sorry gotta ask brake caliper and hose were NEW, you did not allow caliper to hang down supported by hose doing repairs?

When I see the price of OEM I think aftermarket.
When I see the quality of aftermarket I think OEM.

Appears to just be drivers side now but won't know for sure till I replace the passenger side wheel hub now because the bearings are fried. Originally it was just the passenger side and I replaced the caliper which was sticking and then the hose. Calipers were never left hanging.

Then I test drove and the drivers side seized up but the caliper release so its not seized so I replaced the hose. Haven't re-driven since then. Hope to change the hub tomorrow if its not raining.
