A hydroboost makes a world of difference for engines that don't produce enough vacuum for traditional braking systems. A guy who built a radical street Camaro with a nice thumpy cam couldn't figure out why he had no brake assistance from the traditional vacuum boost. We recommended that he try out a hydroboost from a Chevy Astro van for its compact size.

On custom brake pedal set ups, I've used a wood dowel to get the measurements just right for proper travel and etc. Sometimes you cut it three times, and it's still too short.....
