Anyone out there switch their truck from vac assist to hydroboost? I know the tahoe and suburban are using it, i'd think their brake setup as far as pedal and master cyl would be the same so swapping power steering pumps, lines and swiping a complete hydroboost system would be a simple switch? The I was thinking of converting my rear drums back to discs or if the valve will allow it keeping them.
