Hi!
Think I lost the powerbrakes, when i brake I have to push the pedal hard.
What can be wrong?

Is it the mastercylinder and booster?

Thanks
Jimmy

Did you check the vacuum line to the booster. I had the same symptoms and the line had come off. Or have you lost engine vacuum. If not then it is the booster because you still can stop just no power.

Thank you for the answer, no leaks at the vacuum line. So it must be the booster.
