I am in the process of getting the brakes on my wagon done. I am doing the front disc conversion and upgrading to a dual master cylinder. So far they are in mid swap on the discs and that seems to be going pretty smooth ( fingers crossed here). Got spacers with the disc kit but not sure if I am gong to need them or not. Plan on running 31's on 15x7 rims.

Main reason for this post is the shop called me today and said that they are running into clearance issues with the master and the steering box. The front of the master protrudes out and hits the steering box. I contacted the place I bought the master from and they said that some wagons have clearance issues and that it may require some grinding. I am going to go by there and check it again tomorrow - just wondering if anyone else had done this conversion and run into similar issues. I ordered the correct one for my year wagon ( judging by the title) but was wondering if there may be some variation anyway.

As always, comments/suggestions are welcomed and appreciated!

Sorry, I'm of no use to you as I got rid of the OEM steering box before the dual MC upgrade. So mine went in fine.

I'm on lunch now and going to stop by the shop. I'll post up what I find out.

I would love to change the steering too but a tight budget forces me to choose my battles one at a time. i'm going to get it stopping and going first, then see what is next.

Went by - both front discs/calipers/lines are on, hubs cleaned and relubed and on. Working on fitting the mastercylinder. Looks like we will have to shorten one of the mounting brackets. Hopefully not too big of a deal. If I can figure out how to size my pics right I will post some in this thread.

UPDATE: Dual Master Cyl fit and disc conversion?

Went by the shop today. The mechanic that has been working on my wagon was in a motorcycle wreck so I am on hold temporarily. Thankfully he is OK, just beat up and slowed down. That is OK, at least he wasn't hurt too bad.

I think I asked this in another post but does anyone have a digram of the emergency brake system/cable routing etc for a 62/63 wagon? I am missing some parts and cables. Whle I am waiting on them I can at least research this so I can see what I need and where to get it.

thanks ( sorry - no good pics yet)

Stopped by today to see how things were going. Looks like they are getting somewhere. Master cylinder is in ( tight fit) , front discs are done. Most of thenew lines are in. They are working on the rear. I know I asked this earlier but I got no reply so,

Does anyone have a diagram of the E brake system? I am missing everything at the back. They say that they should have it ( wagon) back to me next week, minus the E-brake working.. At least then it should run and stop. Then I have to pick the next repair and save up some money. I am thinking steering and emergency brake when I get it back. I just need something to go by to source parts on the e-brake.

thanks

I have a factory drawing of the stock setup, but it is at the house, and I am not. So if you check back around 7pm central time, I should be able to scan it in for you. What year is your truck?

Imp71,
I've been gone a while and just saw your post here on the E brake. I'm probably a day late and dollar short, so to speak, but it seems to me you are unknowingly reinventing the wheel. If you don't have the existing parts on your Willys; call Willysamerica, or Walcks 4WD, or any other Willys vendor. As long as you know the year and model there is no reason why they can't send you the proper items. Ok, so maybe you already know this, but aren't quite sure what parts you need. Well, there's really only two parts to the "rear" section of the E brake system. The cable (which comes with the necessary hook ups on the ends and the adjuster (which is really it's own entity) but you might not have it either at current time. The diagram posted by Bio is really the only type I've ever seen, so you may just have to feel it out a bit. But really, just tell the folks at one of these shops that you need the rear cable and adjuster set up and you're all set. I know this because I just got mine last spring. Good luck with it.
Steve

Thanks. Every bit of information helps. Now with the diagram I can compare what is on there and I have names for what is not. I am missing at least the rear cable portion. Also missing the internal e-brake parts inside the rear drums on both sides. I was hoping to be able to identify all of this and have it taken care of while they were in there already doing the rest of the brake system, but I may run out of time and money first. They have had it for a while now and I think they are ready to get it out of there. Plus if I can do some of it myself it will cost less, and I might just learn something :D

I got the dual master from Herm the Overdrive Guy and the disc conversion from Kaiser Willys- NOARS ( North Atlantic Offroad Specialties. It was kind of expensive and I am sure that by the time I pay for the install it will be even more so.

I didn't feel comfortable doing my own. If you are able to do it yourself you may be able to put together the conversion much cheaper than the kit costs. I chose this one because it was supposedly bolt on with no mods. I have to talk to the mechanic again but he did say that it went on pretty well. I think that there is a thread on Jeepforum where the person bought there own parts and did it. Think the name is Sub8Haven. Maybe one of the more knowledgeable members on here will jump in with some better info than I have. I am happy to share any info/experiences I have. Hopefully it helps.

On mine he did have some trouble getting the master to fit because of clearance with the steering box. I still don't have the wagon back but when I get it and get more info I will post. It is all on there now and they said it stops well and doesn't pull. I'll let you know..................

I am planning on trying to keep mine with the original drivetrain and all that unless I find it will not do what I need, or it breaks and it makes more sense to change it then repair it. I usually don't have to go far, and I just plan on using it to run around town and go to the beach.

Tom,
Thanks for the info. I am gonna be doing as much as I can here at the house, I fortunately work for an auto repair facility as an assistant manager, (out front). So I have some guys in the shop to bounce ideas off of and also bribe over to the house when needed with pizza and beer. I still have a way to go that is for sure.

Saw my wagon had moved so I just stopped by the shop this morning ( pass it everyday on my way to work). Brakes are done. Still have to get together some parts for the rear drums and e-brake but it stops and lights work.

Now that it stops we have to try to make it go. I am going to let them adjust the clutch and try to get it runnning smooth enough for me to drive it back home and on short trips. Then I will take over until I get in over my head again. Hope to get it back this friday as long as nothing else comes up.

They did say that the disc conversion kit went on pretty well, maybe some minor mods but that is it. Like I said before the master was a tight fit and took a bit more work. When I go up there friday I'll get them to go over all of it with me and let you all know what they thought about the parts and how they fit.
