Hi, the reason the pedal goes to the floor is because the brake line going back to the rear axle blew, first you will need to find where the hole is and cut out the bad section, usually you can find a clean spot further down that you can cut out the bad spot. you will need to go to the parts store and get a new piece of brake line and a tubing cutter and a double flare kit. usually you can rent one of these to save money.

2007 ford expedition wont rev past 2500 rpms in park or goin down the road

Start by checking your TPS switch (throttle position sensor) located on the throttle body . They turn while your foot pushes the accelerator pedal . TPS voltage goes from 0 to 5 volts and is easily checked with a volt meter .

Break pedal goes to floor but still has ablity to stop

Check that vacuum line to the servo or booster (as it is sometimes called) is attached with no holes in it if that looks good then its probably the servo. the servo is what your master cylinder bolts onto. this happened to mine, to replace simply unbolt master cyl. from serve the unbolt servo by reaching under dash just above brake pedal and pulling carpet down and remove the 2 or 3 nuts or bolts holding servo then pull servo from firewall and replace.
