14 bolt gurus

So I got the 14 bolt tore down today and all the brake lines pulled off. I want to order disc brake parts later this week. My debate is the calipers. I need to keep my e-brake so I only have a few options. I know you can use eldorado calipers but you still need to fab a mounting bracket for the ebrake (not a hard thing.) I have also found some newer large rear GM calipers that have the the e brake bracket on them. Either way their not cheap the website that I found them on they're both the same price anyways.
here's the website: http://www.tsmmfg.com/3120.html

Now my next debate is rim size. I was planning on going 16" but a buddy of mine just offered me his 35/12.5/15. I've read that you can fit 15's with a bit of caliper shaving but I don't know if that's going to be true with the larger gm ebrake calipers?

Open to any suggestions or other options. Keep in mind that I'm going to stay with my stock ebrake and not interested in a line lock or any other such form of brake system.

15" wheels

on a 14 bolt? That is gonna be a tough sell. I had a set of 15" wheels on a 3/4 GMC with a D60 in the 80's, but that set of wheels was and is the only set I have ever seen. Might want to check into that a little deeper.

I think I'm just going to have to get my disc breaks installed and then take some measurements. Would be fantastic and way cheaper if I could use the 15" tires but if not......guess I'll be shelling out for some new 16" ones

Why not run a driveline e-brake? Disc brake set ups are dirt cheap for a 14 bolts if you use GM 1/2 or 3/4 ton front calipers. With the gm calipers only minimal clearanceing is required for the 15" rims

Check out DIY4X.com for a disc set up

I am using the large GM calipers from them. I cant see them fitting inside a 15" rim, they look pretty close on my 16.5s. I will try to remember and get a pic in the morning.

Ok so I know I said I wasn't going to use another type of brake but I have been doing a bit of research on line locks. It seems that the electronic/hydraulic ones bleed off and aren't trust worthy. On the other hand the mechanical 1/4 turn ball valve line locks like swagelock actually seem like they could be an option. Keeping in mind that this is my daily driver and the wagon will be in park also while the line lock is engaged. Its also very cheap and would be at least half the price of an ebrake caliper set since I would use the standard 3/4 gm calipers and a 20 dollar line lock instead. I'm gonna need to talk to my mechanic and see if it will pass inspection here in NC. Any experiences with line locks?

thats awesome thanks. How well does your e brake work and how hard was it to set up?

Not hard to set up, just mind the "do not pump brakes until e-brake is adjusted FIRST" or something like that. There is a warning paper that comes with them. It will throw the adjuster inside all out of wack.

As for how well it works,.... I dont have my rig driveable yet, so...
I did latch on to it with my truck to move it a couple days ago, forgot the e-brake was set.
My 2wd truck wouldn't pull it on the gravel, just spun, then I realized why. Rolls forward at idle with them off.

I rigged up the stock cables to work temp, then ripped them out last weekend, cause they were in the way and pissed me off.
Gona get a couple hand levers next time I do a junkyard run. Possible cutting brakes??, that has been my plan all along. I will try it anyway, not sure how well it will work, but........

No pics today, its coming down right now. Dont want to ruin my camera. Sorry.

Jim

no worries, thanks for the info. I think im just going to go with the gm calipers w/ ebrake and keep my stock set up and run 16's. If I need to later on I can always throw in a line lock for cheap

So Im getting closer to completing my axle swap. I have the 14 bolt and all the parts for the disc break conversion. Just need to figure out if I need longer lug bolts or not. My next thought is how the 1350 yolk pinion is going to mate up to my current set yup (stock 89 GW- I think a 1310.) *****remember newbie to all of this!***** I've thought about just upgrading my rear shaft and going with a 1410- yet more money. But the ultimate plan in the next few years Is to drop in a diesel and I'll need a much shorter shaft then. So I would like to just make due with what I have for the moment. So the question is what if anything will I need to mate my 14 bolt up to my stock shaft and slip yoke.

Plumbing e-brakes

Ok so its almost time for my yearly inspection and I haven't rigged up my new ebrakes yet. I have 5" of suspension lift and a 14 bolt with eldorado calipers. Anyone know of an ebrake set up that will work? and and all suggestions welcomed!

I just completed a 14 bolt swap with discs and no parking break I am going for a driveline parking brake. What transfer case do you have? What are the rules you have to conform to?

I have a np229 and have already installed the ebrake calipers. They were quite pricey compared to standard calipers so I'm kind of committed. I've looked at line locks etc. eventually I will be placing in a 6bt mated to probably an nv4500 and np271 (specifics could change). I would be interested in what time of drive line parking brake you went with.

I haven't done it yet. I have a door issue to deal with and then a wheel issue. After that it is the driveline parking brake. Advance Adapters makes a 'kit' for their Atlas case. But so do some other folks as well as some 'generic' options. It's going to be at the transfer case for sure. It had not occurred to me but reading up on it there is a mechanical advantage to a drive line brake. The disadvantages are if the drive shaft breaks.

Interesting, hadn't even thought about that. None of those types of changes would be in my near future though unfortunately.
