Re: 87 V20 D/D and Road trip Burb
 

I am going to be swapping a Dana 60 front into my truck next month and I will be swapping to the 1ton Hydro boost unit and Brake master cylinder.
I have a hydro setup already but it covers the lighter gvw.
Has anyone run into problems swapping these?

I don't anticipate running into problems if I swap both the Hydro unit and master.

I don't know about the swap, but that down hill pic into the valley? Wow.

Re: 87 V20 D/D and Road trip Burb
 

Looks like I have a JD7 brake system for my Burb.

I am going to get the matching pair for the same yr V3500 and go with it.
The part #'s are different between the 2 hydros and master cylinder.
Is there such a thing as JD8?

Re: 87 V20 D/D and Road trip Burb
 

I'm not 100% certain, but I believe the "JD8" might refer to the larger brakes that were available on some 1-tons. I'll have to check the RPO sticker on my K30 when I get home. I do know that the JD7 brakes on my '86 C20 Suburban (13x2.5" rear drums) are different than the brakes on my '86 K30 Crew Cab (13x3.5" rear drums). I haven't gotten the front end apart to see if the rotor size or caliper are different yet. I'm running the JD7 hydroboost with a master cylinder from an early 2000s 8-lug Chevy van, and have found that to be a really good combo. I went with the van master cylinder, because it had a reservoir about twice as large as the normal plastic squarebody master cylinder, and it was cheap in the salvage yard I was crawling through.

I'm planning to swap the larger rear drums over to the 14 bolt that is already under my C20 Suburban when I do the 4x4 frame swap. I'll swap over the front brakes also if they're beefier, or maybe do the '09-up Ram 3500 front disc swap on the Dana 60 while I'm at it. Still looking into whether or not that will fit into my 17" H2 rims.

There is a member here that goes by SCOTI. He has a crew cab and I remember reading some good info from him once about the HD brakes. Might search posts from him related to brakes or shoot him a PM.

Re: 87 V20 D/D and Road trip Burb
 

The JD7 brakes are what I run on my Blazer. They're a bolt on for the half ton if you have the right year banjo bolts. Easy fix if you don't. The one ton brakes are a totally different animal. Not sure what all you have to change to make those work.

Re: 87 V20 D/D and Road trip Burb
 

Well it appears that I was wrong about the 4l80e not needing a controller.
I got 2 options.
One is spending a few hundred $ and buy a controller, or use the harness and computer from the 91 parts truck.

I am going to keep driving it as is and do some more research on the swap.

so as far as the brakes are concerned.

I went though the rear brakes, readjusted everything, bled them a bunch more times and got the brakes working good again.
After a few wks of driving, the rears are slowly starting to grab a bit more every time driven. They now are locking up occasionally.

Looks like I will be back in the system again. I wonder if I got the adjusters in backward.


I had to put off my trip north to pick up the 60 until the end of this month. I picked up a matching master cylinder and hydroboost unit for a 87 K30 with a 6.2. I will swap them and a new power steering pump after the 60 goes in.

I need to try to keep up here.

I have been just busy with life. I just got back from a trip to Southern oregon.

I have family and friends in the area and I was up there visiting a brother in law that was involved in a serious motorcycle accident. While I was up there I picked up another piece of the puzzle.

A month ago I picked up these tsl's and mounted them on some stock steelies. The dilemma now is what color to paint them.

Re: 87 V20 D/D and Road trip Burb
 

That last pic inspired another thing to add to the list.

A sunvisor. But not a re -pop. I want the rounded edge version and they are proving difficult to find and $$$.

I found the one I wanted but missed out on it. After finding out how difficult they are to find, I had to jump on the next one that came up.


I hope to go pick it up next month.
Here is a pic of the style I want.

Re: 87 V20 D/D and Road trip Burb
 

Here is the actual one.

It came off a similar colored burb. I hope it's in good shape.

Re: 87 V20 D/D and Road trip Burb
 

Which leads me to this.

Boom!

A trailer that can fit my burbs!

My father in-law was selling it so I jumped on it too.


I feel like I hit the lotto, but it's all hard work as payments.

Re: 87 V20 D/D and Road trip Burb
 

It’s been a long yr.

I’ve been working on a friends truck that passed away. It’s a 75 k10 with 1 tons under it.

I picked up this 84 c30 with a 6.2/400 combo, in the hopes of building a tow rig.

I also got this Badass Buckstop Bumper!

Re: 87 V20 D/D and Road trip Burb
 

Lots of cool stuff going on in this thread. Funny I saw the "visor" in the pic too and it looked pretty nice.
