Brake problem

[mrkgreen]

I just replaced the caliper on the drivers side, of course I bleeded the line so I filled it back up with brake fluid. But when I start my car the "brake light is on" and my brake pedal is so loose it doesn't brake, what did I do wrong?

You probably need to go back and bleed the entire system. When you "filled it back up" did you bleed it or just refill the reservoir? Once there's air in the system, it can go into other lines, not just the one you worked on. Bleed all 4 brakes, starting with the one farthest from the master cylinder and working your way to the one closest to the master cylinder. It's a 2-person job, unless you have speed-bleeder valves on each caliper. Keep the reservoir topped off, and bleed each one till new fluid begins to come out of the lines.
