I was drveing down the road and all the sudden the break pedal went all the way down to the floor and it will stop but it takes a long way back to were you gotta stop to fully stop please help

Did you break the metal brake line on the back axle ?

You should take your car back to the person or place that you fixed it and tell them it is worse than before. Insist on getting your money back if it is not fixed.

Don't you have a puddle on the floor somewhere? If you are going through that much fluid you should see it somewhere. Maybe even leaking through the firewall and onto the floor, which would indicate the master cylinder is bad. Look under vehicle, and at every wheel you should be able to find something that is wet. If it is none of that, is the engine smoking all of a sudden? Maybe it is getting pulled out through vacuum by the brake booster? Just trying to give you something to look at.

Without being hurtfull. Just take it to a repair shop. Stop quessing at something your not familar with.

There is air in the line try rebleeding the system if it was at a shop take it back soon

Could be a defective master cylinder or a brake fluid leak some where, have it check out as soon as possible.

Most likely there is air in your brake lines. You must have them bled.
I have yet to find a good brake shop that can do this right. Make sure they road test it. If it doesn't work right when you drive it, take it back and make them do it right or get a refund.

Your master brake cylinder can also be worn; however, the pedal will sink to the floor slowly and you will be able to "pump" the brake pedal.

EIther the ABS pump is bad and will have to be repaired by the dealer or specialy licensed ABS mechanic, or you can do what I do and pull the ABS fuse under hood and not use them.

sounds like your brake cable has broken or there is something damaged in the pedal assembly.........try pulling on the release handle and move the e-brake pedal back to its off position by hand at the same time.(you may have to tie it in this position to keep it up)If that doesnt work there is a sensor on the pedal assembly that you should be able to bypass by either disconecting the wire(1 wire system) or connecting the two wires together (2 wire system)Especially if your truck is a standard the e-brake is an important safety feature,so if these steps fix the light and dinging problem you should still take the steps to have it repaired.
hope this helps.........Good Luck!

That guy may be right. To check booster function, press firmly on the brake pedal with the engine off, then start the car. If the pedal sinks and inch or two, then the booster is probably OK.
If it was mine, I'd take it outside of town to somewhere with little or no traffic and test the brakes pretty brutally on a straight road with a loose grip on the steering wheel to check for directional problems.
Something that might have happened is that one wheel had a stuck wheel cylinder that suddenly got unstuck, causing a drop in pressure momentarily. I have also had the entire brake material on one pad separate from the backing plate which caused the same thing - at an intersection, with a very busy highway that wasn't crowded for once. I shot right across the intersection, drove home carefully and checked my shorts.
If you can't find anything yourself, I wouldn't hesitate to take it to an honest service shop (in the US, check local BBB) since that is something that shouldn't be put off.
