pedal went to floor then caliper stuck
 

Brakes were working fine. One morning I got in the car and my brake pedal went to the floor all the way but still stopped the car barely. As I drove it tightend up a bit over the next 5 miles. Now its working fine. Drove another 10 and the pedal started to get stiffer and stiffer until the front right caliper stuck. When I pulled over it was smoking. I opened up the screw to release the pressure and fluid shot out. I got home using the e brake to stop as I didnt want it to seize up again. What do you think the problem is? caliper? master cylinder? any thoughts?

Check to see if fluid is leaking from the master cylinder, if there isn't any fluid there then its probably the caliper.

Ill check the master cylinder but the reservoir under the hood was full...

no leaks in the master cylinder
