Brake petal has no resistance, it goes all the way to the floor. Car will not stop.?

I have a 2000 Ford Focus and my brakes were going bad.. so everything was replaced by a professional mechanic. New brake shoes, pads, rotors, calibers, master cylinder, and brake booster. Now I have no petal, when I press down on the brake it goes right down to the floor and gives no resistance at all. The car does not stop. The mechanic doesn't know what is wrong with it and cannot fix it. I'm looking at forking over MORE money to have it looked at by someone else and I have already gone into considerable debt just on the work that I've had done. If anyone can offer any answers, or suggestions about what may be wrong, it would be greatly appreciated! Thanks!

the mechanic needs to re-bleed the brake system.


IF the car has ABS (anti lock brakes), the dealer is probably the only place that can bleed the ABS system. a scan tool has to be plugged in and actuate the ABS valves to purge the air in it.


IF the ABS system was opened up, it'll need to be bled.


if it wasn't, it should be fine.


a brake pedal that goes to the floor is a sign of a bad master cylinder or air in brake lines.





all those things that were replaced were unnecessary unless they were broken.


brake boosters rarely go bad, as does master cylinders and calipers. it's possible, but something doesn't sound right.





Even a NEW master cylinder can go bad! They are made by man, man is not perfect.





You need to inform the mechanic that you want to see your old parts next time, and/or take them with you.


and also, make him prove the parts were bad.


replacing the booster %26amp; master cylinder are not standard brake replacement practices.


a bad power booster will make the brake pedal go hard. so hard you could stand on it and it'd barely move.





Also, it could be the connecting bar between the booster and master clyinder aren't connected properly.
Reply:probably master cylinder
Reply:Pads and possibly rotors I can see master cylinder and booster no way should have been needed. Not only did you get ripped off but they did the job badly, did not bleed the brakes off correctly Would get an attorney and have this problem paid for by the people who obviously ripped you off
Reply:Were the brakes properly bled when the brakes were done? Is the brake fluid level filled to the top in the reservoir? Do you have a fluid leak somewhere in the system? These a very basic questions and if the mechanic was competent he would know this.
Reply:You still have air trapped in the system. Your mechanic needs to rebleed the entire brake system. But i would look at a defective master cylinder as well. This same problem happened to me recently too. A defective master cylinder.


Why did you need to replace the booster? This is trare when then go bad! I own a car from the 70's and the same booster is still in there working just fine! Were your brake hoses replaced too? Sometimes the hoses deteriorate internally and traps the air in the hoses causing a no pedal or brake pull.





good luck and feel free to e-mail me with any questions.....
Reply:This is the simplest thing to do first: check the brake fluid level. It could be that when all the work was done on the brakes before they changed out the fluid and either didn't replace it, or didn't tight everything and you've developed a leak. You can always test it yourself by adding brake fluid (if it shows low) and if it leaks out fast, you'll know that someone didn't tighten everything. By the way, it'll take a few times pressing on the peddle before the brake fluid gets all the way through the brake lines.
Reply:check the fluid level and get someone to bleed the breaks.Also if you are not using correct fluid it may cause this and old rubber brake lines,when they get old they will become soft and flexable and when you hit the brakes they expand like a balloon.Still sounds to me though like the master cylinder or break booster.
Reply:Like the other people said, It sounds like air in the system, low brake fluid level, or bad master cyl.





Start with easy stuff 1st.. Check and fill brake fuild.. Then bleed the system.
