Not sure what you mean by "all 4 wheels lock up". Do you mean they start binding when warm, or that when you step on the pedal all 4 wheels skid (or activate the ABS)?

Also, when you bled the front brakes, you say you're not getting any fluid to them. Meaning... nothing comes out the bleed valve, or it's not pushing the piston?

Regardless, I don't think further bleeding is going to resolve your problem.

Try pushjng the caliper pistons in,if they do not go in easily try disconnecting the brake hose, if they now go in you have a bad brake hose. Good luck

Could also be corrosion in the calipers causing the pistons to bind up possibly!

Thanks for all the suggestions,kinda thought it might be the calipers having corrosion also,I do live on gulf coast so even though it was in garage was still in humidity,so I ordered all new calipers,will be here tomorrow and will post if that works or not.
