Russel PS fittings # 648060, 648080 metric to 6an on HB unit Hydroboost unit #52-7333 Cardone, (Rebuilt) I know people have mounted the Astro unit on the stock angle bracket with the Ebay bellcrank kit, but I'm not sure if the Tom's bracket is the same. Anyone know if this bracket is the same as the stock Ford 76-77 bracket? I want to mount the Astro hydro on this (to clear my EFI upper). Like I said, I have the Tom's Broncos angled bracket vacuum booster. Should this be similar to the Astrovan proportioning valve so I don't need to pull the Astro one.or is the Astro one metered specifically for the hydroboost and MC so I should pull it? If I have either of these proportioning valves already, is it better to install one of those adjustable valves so I can dial in the rear brakes better or I should be fine? I think I bought it from Tom's Broncos with teh vacuum booster. I already have a disc/drum proportioning valve (not the original stock H block) running with my vacuum boost unit. My question is, as standard practice, should I automatically rebuild the hydroboost unit (seals) with one of those online rebuild kits? Of course if whatever I pull is covered with power steering fluid, it probably should be an automatic rebuild because it's obviously leaking.But if it's not obviously leaking and at least from the outside looks to be in good shape, do most of you rebuild it anyways since it's a 25-30 year old part?Īlso, if not trying to keep the cost down, should I pull the master cylinder too or just buy a new one from RockAuto or something to ensure it's working well? I'm probably going to go the pick-a-part 90-95 Astro Van hydroboost route. Figuring out everything I need to do to dive into converting to hydroboost.
