Hydraboost brakes - The 1947 - Present Chevrolet & GMC Truck Message Board Network

77gmcjoe · 11-11-2004, 06:43 AM

Just wondered if someone could tell me me advantages of hydraboost (sp?) brakes. I've got the whole system on a parts truck and wondered if it would be worth the time to convert my '77.

Thanks,
Joe

Thanks for the response, ZOOMY. Would you know the reason they're always on 1 ton trucks? Higher pressure or something? Would a transplanted 1 ton front axle with the 1 ton's brakes need the hydraboost?

I believe there usually on 1 tons cause hydro boost brakes stop better. 1 tons are usually towing & are very heavy. Hydro's will help said vehicle stop faster. Im building a 71 3/4 ton & want to do a hydro brake system. I havent started to search for parts yet. Let me know if you want to sell your hydro stuff if you wont be needing it. Its a bit of a pain to set up the hydro system, & i wouldnt be considering it but i tow to much. My 2004 3/4 ton suburban has it & it stops so much better while towing. Let me know. Thanks Todd

PS: Im in Illinois too. So hey ho neighbor.

Hi, I have a complete hydroboost setup on my plow/parts truck. I was planning on converting my stepside when I add the other hardware. I am curious too as to why the hydroboost is better, I just figured it would make sense to transplant everything so it would all match. Thanks!

Thanks for the info. It will be a while before I can pull all the brake stuff off (I'm still gonna have to move it after I get the engine/trans/transfer out), but when I do I'll let you know.

Hydraboost stops better than any vaccum booster I've seen. My 80 C-30 weighs 7000lbs.empty but stops like a pickup.Before I installed a bed it would lock the rear tires just tapping the brakes!

I've had my truck 15yrs. and had no problems, just changed PS fluid & new belts every so often.

77gmcjoe · 11-23-2004, 09:00 PM

Looks like a nice dually.

77gmcjoe · 11-28-2004, 07:02 PM

Here's some pics of the hydroboost setup.
Now it's Miller time!

I was wondering, since I have the brake set up pictured on a parts truck to, is there a special power steering pump that should go with it, or will the standard single outlet pump work. I was thinking on swapping this on my 1/2 4x4 just for better braking.

687980chevy · 12-01-2004, 11:50 AM

The pump on my 80 c30 looks a little bigger than on my 79 k10 maybe just extra fluid ? Both are 350ci

69k5 · 12-03-2004, 08:44 PM

the standard pump can work but if its old it will kind of pulsate. you can go to west texas off roads website and see the mods to up the pressure. the low pressure is what causes the pulsating. a hydroboost pump is the best. i have one off a 84 m1008 (military blazer) and it fir in the bracket for my 69 350. so might try swapping them. only prob I had was where one line pointed off the pump so I CAREFULLY bent it around.

If you have hydroboost and havent changed your power steering fluid in a while, DO IT, I used some Valvoline Synthetic PS fluid in mine, with a 6' length of 3/8" hose over the return line into a washer fluid container, ran about 2 quarts thru and it stops like a new truck, altho I am talking about my '01 with 145xxx miles... It really makes a difference tho.. Oh, and if you have hydroboost, you could run a REALLY BIG CAM
