Did the LS1 brake upgrade all new stainless brake hoses lines calipers pads rotors passengers front caliper locks up and can't figure out why anyone else had this issue?

 

Hose kinked or kinking when you turn the wheel? Slide pins strait (not bent) and lubricated? If those look ok, then try removing that hose from the caliper and pedal pump fluid through it. Also you might have an obstruction or kink in the hose that the fluid gets past when you apply pressure but restricts the fluid return when you let off the pedal. If all that looks ok then return that caliper for another and try again.
