Pretty sure my installer messed up the brake booster hose step on my automatic. The brake pedal is very hard to press, and my ABS and Traction control lights are on. I have a pretty big boost leak as well.
Also, should there be a check valve between the brake booster and vacuum pump like there is stock? (asking for my installer)
