My truck now has vac boost brakes but the booster is bad is it worth trying to change over to hydro boost brakes? or should I just replace what I have now?

 

I'm sure it's much more easy to replace the vacuum boost.

 

Replacing the vacuum booster involves 6 nuts. Hydroboost conversion is a little more expensive and involves some light fabrication.

 

If you have the time, money and ambition go hydroboost! Hydroboost rocks, I have had several old Chevy's with hydroboost, every truck should have come equipped with it. Some very light fabrication, a few bucks into the equipment, and a few hours time you'll have a nice setup. Go for it!

 

I also vote Hydro. I love it. I put a Ford unit in mine cause I didn't know Dodge made a hydro unit.. duh

So it was a fair amount of work but well worth it.

HYDRO-BOOST will stand you on your nose.

 

I have read many other threads on hydroboost conversion, I picked up a used hydroboost from a 1985 chevy one ton dually mainly for the cores and brackets. I found a 1994 chevy one ton aluminum master cylinder (RPO JB8 10,000 GVW) which has the proper end configuration, disc/drums, and brake ports to mate with the older hydroboost and dodge brake lines. $99 for new, no core at Autozone. The CTD master cylinder will not interface with the chevy hydroboost as the push rod hole is too deep.

PSC and AGR both reccomended their heavy duty pumps, I am also adding a milemarker hydraulic winch.

From what I have been able to research The light fabrication requires you shorten the brake pedal shaft by 3/4" or space out the chevy bracket with some 3/4" spacers. I am going to try this first to keep the hydro unit a bolt in.

 

Thanks for the input guys

 

Does any one have photo's of their hydroboost install and some details of what needs to be done ???? Also DEAN M HOW DID YOU DO THE PORSCHE PARKING BRAKE SET-UP. My parking brake gave out about a year ago and a pain to replace/repair. I suspect this is common fore these trucks. Thanks Augie Dog !!

 

My Dana 80 has disk brakes. I had to widen the Porsche calipers with a spacer. Then I made an adaptor to mount them. Then I plumbed a hyd handpump in the cab to actuate the calipers.

I have some pics on my computer, email me if you want some.

 

Summit has a bolt-in kit for about $480 that supposedly fits a '90 to '93. Plumbing is NOT included.
