Brake fluid leak rear driver side

I got a two wheel brake service, left front new disc brake rotor, right front new brake rotor, clean and adjust rear brakes, and replaced my left front bearing. Since I have had these services done, I have had nothing but problems with my brake system. I noticed that when I traveled long distances that I would start to smell something near my front brakes burning. I would pull over and I could see the smoke coming from under the car near the driver's side brakes. When I got back in the car, the brakes would go all the way to the floor and would barely stop. So I checked it out and the brake flex hose on the right front is bad. Please help!
