1995 Chevy Corsica brakes sticking

I know you probably bled them so I will skip that. LOL I know that some of the valves stick on the abs side. It should have bleed valves at the valves for each wheel. Try bleeding them. If that doesn't work it may be the wheel sensor not working on that wheel. This should cause the ABS light to come on but not always. This would cause the wheel to grab and lock up.
