Hydroboost problems..
I need help!!! I Have a project car that’s using a Hydroboost brake system out of a mustang because a normal vacuum booster does not fit. I am having issues with it, was wondering if you guys could give a helping hand on possible Hydroboost do’s or donts, or specific bleeding procedures? Brand new master, got a mustang Hydroboost kit including pump. Installed everything, drilled pedal 3/4” higher. Bled brakes, bled PS system. Pedal goes to floor and stays there, have some rear brake action but less in the front. I can still turn the wheels with my hand when pedal is to the floor, I can feel friction. Any ideas what this could be??? Been at it for about 2-3 weeks and have 0 clue what could be the issue.... |

A manual will tell you to use a vacuum bleed system which is very complicated and requires tools that many shops do not have. Another alternative that we find works well is as follows:

Haha yes I have read these exact imstructions and did this exactly already. |
pedal rod length incorrect?

So I have another question, do you guys know if you have a properly working master cylinder, if you remove it from the booster/hydro is it possible to fully compress/push in the piston by taking the master and pushing the master with your hand against something hard like the edge of the booster/hydro, or firewall? If that made no sense I totally understand haha |
Sounds like a faulty master, i don't know what your experience level is but you do realize bleeding the booster is completely different than bleeding the brake system.
If the peddle is going to the floor you have a brake system issue |
