brakes and steering

archie87 · 10-28-2009, 02:59 AM

1- was wondering if there was a master cylinder I could swap out that would push more volume to the brakes and still adapt to the 84 brake booster?

2- I was planning on sometime in the future wanting to go with a hydro assist on the truck and after this weekend found out it would be really nice to have. I know how to set it up but I have one concern and that is Im not really sure if the factory84 s-10 box could be used to tap and push the ram and if it would work, is it big enough to pump enough for the ram?

I think a master cylinder off of an 80 2wd 3/4 ton suburban works? But i only think i read that somewhere. i would def wait for someone else to confirm.

as for the steering,
check out S-ton's build tread..... he tapped the steering box for hydro asst.

he's got....... V-8, 39.5 tires on 1-ton axles and hasn't had a problem yet

archie87 · 10-29-2009, 07:37 PM

I looked and its looking like he used a astro van box and I still have the factory 84 box, would it still work to tap it

BuzzerPB · 10-29-2009, 07:55 PM

if thats the box you plan on using..i don't see why not...
and yeah, his is the astro box.

96superflow · 10-29-2009, 08:14 PM

the boxes i believe are the same, just the inside is what makes them operate different???

archie87 · 10-31-2009, 06:59 PM

what is the difference in the 2?

the s10 box, the pitman arm points toward the back of the truck
the astro box, the pitman arm points toward the front of the truck..

the astro box is really only needed if you move your axle like 6" or more forward.

i was around 4-6" forward and used my stock s10 box.

correct, I think it has a 5/8 cylinder inside that will push a greater volume of fluid. i think the push rod needs to be modified not sure. people have done this upgrade to on rear disc conversions trying to compensate for the added volume of the rear calipers.

archie87 · 11-02-2009, 09:00 PM

thanks will have to look into that, future plans are rear disc.

I found a deal on the hydro steering where you can tap the box without dissasembly. All that is needed is to change the frount cap to a machined one with the threaded hole and then take off the four bolt cap on top and tap it, the machined piece is around 50 bucks and it a simple job, i will try to find the link again.

That model Suburban has rear drum brakes, which take less pressure to continue braking than do disc brakes. You might could get away with doing this and running a proportioning valve, but in a straight swap I probably wouldn't run this MC with rear discs. I would likely go Corvette or something first.

I happen to be running this Suburban MC with the drums on my 9".

So the corvette might swap out also?

Jeep / late model GM Hydro Steer Cap

This cap will fit Jeep Wrangler 89-06, Chevy S-10, some Dodge and 88 and newer GM trucks. However PLEASE verify the diameter of your cap before you purchase, even on the models that I say it will fit. Please understand that there is no way that I can verify every vehicle this will fit. The diameter of the cap is 3.10" - that's almost 3-1/8". If yours matches this diameter then it will fit. This steering box cap which will allow you to tap into the pressure line when turning to the right. It is a "bolt on" item - all you have to do to install the cap is remove the snap ring and replace your existing cap with this one. The cap is made from a solid peice of 6061 T6 aluminum. The cap is tapped with a 3/8" NPT thread for your fittings. You will have to tap your existing top cap to get pressure for turning to the left - see the second and third picture. However you can not tap your end cap because the material is too thin to adequately hold threads. This modification can be done with the steering box still on the truck. Others will show you how to tap the steering box casting but this requires a complete teardown of the steering box in order to make sure there are no metal shavings left inside from drilling and tapping. I also do not recommend welding a plug on your existing end cap as the cap is cast aluminum and the stresses from welding will make it prone to crack when subjected to the high pressure of power steering fluid. To find out more about how to add this to your vehicle see these links: http://www.members.tripod.com/surfmac/65html http://westtexasoffroad.homestead.co...rsteering.html http://www.pirate4x4.com/tech/billav...Tap/index.html This is the info others have been selling on eBay - here it is for free. You can also do a search for "redneck ram", "rock ram", "hydro assist" or "hydraulic assist" for more information on this modification.

I have heard of this, yes, but I won't promise you until you look into it a little further.

For F&R discs, I would prefer to go with a MC that is already proportioned to that setup. Alternatively, I would probably want to go with a F disc, R drum MC if that was the setup, like I mentioned.

Search around or see if you can find out from a dealer what MC's will bolt right up, but clearly GM will be your best option, so Vette parts are going to be hard to beat if they can be applied to your setup. Check it out and get back to us, but I believe I have read this numerous times before.
