brake issues

I have a 97 town n country with brake issues. The brake pedal travels all the way to the floor before it slows the vehicle, and it seems to pull to the left when attempting to brake. I have also noticed that the left wheel is extremely hot after driving while the right wheel stays cool. I changed the brake pads about 1 week ago, and about 2 days later is when it started having this problem. The van did the same thing about 6-7mths ago for about 1-2 weeks and the problem just disapeared one day on its own. Any suggestions or advice would be appreciated.

left wheel being hot means caliper frose up or the rubber brake line is collasped in side line and that would make it pull it's not releasing that side caliper/hose. my guess is the line because you pushed piston in to get new pads on......good luck.......
