Re: smaller diameter booster
Can I hijack this thread and start a discussion about the pro's and con's of hydroboost? What happens to the brakes if your engine shuts off? My very limited understanding of hydroboost is that it runs off of the hydraulic pressure of the power steering pump. If this is the case, and you engine stops running (who's doesn't at the worst time... it is a syty isn't it?) what happens to the brakes? Like the original poster, I am hoping for something smaller (twin turbos in my future) but maybe not hydroboost.

I'm not positive, but I'm pretty sure the hydroboost uses an accumulator for that purpose.... lose the engine and the accumulator supplies enough oomph for a safe stop...probably only good for one or two stops however.

its probably no diffrent than what happens to your vacuum brake booster once the engine dies and you loose vacuum.. no matter whats running your booster once the engine dies you loose power assist (unless your running electric booster).

Re: smaller diameter booster
Davey I was at my buddys shop last night and there are some s-10 that have a smaller dual diaphram booster they are longer but like 2 or 3 inches smaller in diameter. He is going to try and get me one he said wont cost much of anyhting and you can have it if he comes up with one but he is using it on his s-10 in plase of the big round one like we have.
I will let you know when I get one

Re: smaller diameter booster
Sure you can. That's why I have manual brakes on my truck. No booster at all

Re: smaller diameter booster
Us "bodydrop" guys use either a first gen JM5 booster, a Geo Metro booster, or I run an aftermarket "hot rod" chrome booster with a 1 5/16 bore master cylinder from a 1 ton pickup.
I may or may not go hydroboost on the Ty, the much bigger master cylinder made a much bigger difference on the brakes than the booster swap.

Re: smaller diameter booster
They all are.The JM5 booster is a direct swap.The only modification to the chrome universal style and metro is the modification of the rod. Measured twice, cut once and 10 minutes with a 3/8-24 die and a threaded sleeve and it was in.
You can get pre-fabbed rod ends here

The larger master cylinder has the same size fittings as stock. Bolted right in, just had to slightly bend the lines going to the prop valve for a perfect fit. :tup:
