My brake line is leaking on the rear passenger side above the axle where the soft line goes into the hard line. I tried to tighten that bolt up that screws into the soft line but I can't seem to find a wrench the right size and it has started to strip it. Does anyone know what size that bolt is and has anyone had this problem before? The brake fluid shoots out of the bolt (towards the floorboards) which to me seems like the problem is not that it is too lose. Any help would be appreciated
