Hi Rich, I rebuilt my entire brake system except the Hydro-Vac, that was a couple years ago. I bypassed the Hydro-Vac by not connecting the brake lines to it, I drove the truck with manual brakes for that time even with some loads. You have to anticipate any trouble ahead as the brakes are not fast acting BUT they still bring the truck to a stop. I recently ordered a rebuild kit for the Hydro-Vac and that project was successful, now the complete brake system is in great shape and I don't think twice about it. My truck is a 2 ton LCF with the factory 283 V8.
