aid

I have a problem, the brake pedal was hard and it doesn't grab it is a 1997 Fordour and I would like to know if anyone knows how to correct my problem

The safest thing is that your master is broken or have some empty leak some part of your empty hose.
We are lucky

Hello,
to check your problem you should be the boster of braking this back of the brake pump carries a thick hose connected to it,
disconnects the boster and czech hose that arrives empty (suction) of the multiple of admission,
if check does not reach it that the hose is not covered, broken or disconnected, if it comes empty and still persists the problem is probably hidden
Good luck and we are at your service

Well I don't think any doubt is left but it is just to confirm is the boster or servo brake is your entire problem.

Hello thanks for the help, it turns out that thanks to its co -empties I found that the vacuum hose is broken from the leaving below but I do not know where it is inserted it seems that I went to a plastic tube or something like that but I find it anyone knows where it is connected, for your help a thousand thanks a thousand thanks
