Question about Hydroboost.... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

East End K5 · 05-12-2009, 08:46 PM

Are hydroboost power brakes or standard brakes? I assume they are power because of the 2 hoses coming off of the p/s pump and going to thingamabobber on the drivers side. I don't have a master cylinder either. Having trouble finding ss brake lines for my app. LMC doesn't seem to sell them, or ones that will fit. I recently ordered lines for a 2wd 1/2 ton thinking that they would...big mistake.

They are power assisted brakes. You have manual brakes which have no assist, power brakes which use vacuum to assist, and hydro-boost which uses hydraulic to assist.

The GM Hydraboost system was used primarily on 1 tons with gas and diesel engines. Hydraboost was also used on other model light trucks with diesel engines.

This will be of great help to you and anyone looking to do a hydroboost setup.

So ss brake lines for a standard system, would work then?

I have hydroboost on my 71 C10. I bought from ABS Power Brake. It came with stainless braided lines. They might have them for sale.http://67-72chevytrucks.com/gallery/...5&ppuser=24433

....well, I didn't get anything for a hydroboost system. Couldn't even tell you what is in the truck. Just looks like a hydroboost set up. What i DID do was order stainless steel lines for power brakes from LMC. and finding out they don't fit.....lovely.....

Also a correction, I don't have a brake booster. I originally said I didn't have a master cylinder...crazy.....
