broke two wheel studs how do you replace them ?

E brake or park brake has nothing to do with the front brakes, only the rear! Sounds like a caliper or flex hose problem if you are working on the front. Might want to get some hands on help with this repar as it is a safety issue!

I agree that it sounds like the caliper is stuck closed. I had this happen to a Pontiac Aztek. I had to rebuild the caliper because it was all corroded. The lug studs are easy on most cars. Just pound it out the back to get the broken one out. Then put the new stud in the back and put several washers on the front side of the stud. Then use a new lug nut and thread it on. Tighten the lug nut to draw the stud flush with the back. It helps to put the stud in the freezer overnight and put a little soap on the stud to help get it in. It is an incredibly tight fit because it just seats.
