hydroboost brakes
I will be running a approx. 400 hp 302 in my 71 bronco and i was wondering if i should go with a vacum boost power brake booster or hydroboost since my motor will probably not make a lot of vacum, and who makes the best hydroboost kit, etc.
Thanks

my 01 Mustang GT has hydroboost brakes. They are awesome.....until you start doing doughnuts with the car. Then..i lost my power brakes AND power steering. that was a long 22 mile ride home. I let the car sit overnight and everything worked fine again. Anyway, go with the hydroboost.

hydroboost 'steals' pressure from the power steering system and stores that to use for assisting brake actuation. Very powerfull..and not sensitive to things like lumpy cams and such that can result in low vaccuum for vaccum-boosted brake operation.
'Hydro-vac' is an ancient term that was used in early early vaccuum-operated power brake systems - systems that differed little in function to todays vacuum boosted brakes. The booster was 'piston type' rather than diaphragm. The 'hydro' in 'hydro-vac' referred to the master cylinder/wheel cylinder part of the system...'hydraulic brakes' being still rather new when hydro-vac came out.

I thought hydro-vac was refering to the hydraulically assisted vacuum booster like bigger trucks used. A pedal operated master cylinder that feeds pressure to another master cylinder with booster. My 57 F600 boom truck and Austin Healey 3000 are both set up that way.
