I have just replaced the rotors and pads on the front end but my brakes are still not operating correctly. The brake peddle still goes to the floor. I suspect that I have air in the line but I dont know how to go about bleeding the line. Can you tell me what to look for?

Take the cap off the master, any fluid in it> if not fill it then watch for a leak...is the tires wet on the inside on any wheel? And last, did you pump the pedal to position the caliper pistons?

I have done everything you suggested without any success. I dont believe there is a leak the brake fluid is at the same level. I have pumped the peddle it feels like there is just a big rush of air. Is there a valve I can open to let the air out and if so what does it look like? thanks for any and all help.

If you did not change any hydraulics, and the pedal goes to the floor, You probably need a new master cylinder...That is if there are no leaks! The other quistion is what color is your fluid? remove some, put it in a cup, add water, should turn milky, with NO oil bubbles floating on top, I assume only BRAKE fluid was used? I have seen people put tranny fluid in thier brake systems...NOT GOOD!
