Brake and clutch pedals

I've got a 1950 cj3a that im fixing up and doing some slight mods to I'm trying to figure out the best, cheapest, and easiest way to convert my willys to have firewall mounted clutch and brake pedals. I'd also like to have it be a hydraulic clutch system and I'm not worried about power brakes but something better than what is stock on the willys. Also i'm running a dana 30 front and dana 44 rear out of a cj7 and no its not the amc20 rear axle. Thanks for the help

XJ pedal pack is a fairly easy conversion. Check out my 'Rango' thread for details. I bought my pedal pack new for $40.

Agreed on the XJ conversion, it looks good.
I have what i believe to be some datsun junk in my jeep, and it works well and doesnt look half bad.

OMIX made the setup I purchased. They all seem to be around $45 to $55. Here is a link to a vendor with the pedals. I had to trim quite a bit off of the top of the bracket but in the end it worked out really well.

I am running a late model CJ master and clutch cylinder with this pedal setup. I used some universal push rods from Speedway Motors to hook up the cylinders. I am curious as to how others have actuated their master cylinders.

This is a picture of the push rods.



It would be nice if Advance Adapters offered a dual circuit master cylinder to work with their kit.

I have a CJ3a and I used a Willwood pedals and master cylinders. Way easy to install and Wilwood has excellent customer service, if you call them directly they will go over your application with you to make sure you purchase the correct items. I then purchased everything I needed through Bryke Racing. In addition to the pedals/master cylinder setup you'll need a portioning valve and a residule pressure valve for the rear if your using drums.

My entire break/clutch system has been replaced. I ordered a break line kit from another company and new flex break lines from Crown Performance. Everything together cost me around 450.

My clutch is hydrolic and Crown Performance was able to make me a flex line to connect the steel break line to the slave cylinder that came with my AA bellhousing kit. Crown will make lines to any length, with whatever ends you need, in many different colors and they're really strong lines with steel braid/kevlar layers.

Hopefully this helps.

I talked to someone from Willwood today and i like the set up but I'm not sure I'm ready to drop $400-$500 for a pedal pack and master cylinders, slave cylinder, and perp valve.

Also I like what your doing on your "Rango" build I'm hoping to make my jeep look like that someday. I'm just going a little milder with my build.

Great info here! If I may... a few questions. So what about a brake set-up for an auto trans application? I assume a brake pedal from an auto XJ would work just as well? For those running a setup such as the Wilwood, do you get plenty of stopping power without a vaccum booster? And while we are on the subject of pedal assemblies, what are you guys using for accelerator pedals? For info sake, I am building a 51 M38 with a 4.3 Vortec followed by a 700R4, and will be running 37" Krawlers and disk brakes at all fours for starters. Thanks in advance for any help!

Well you have a much more broad spectrum as far as brake pedals go. You can get away with using the stock XJ brake pedal only.

However, the good part about being auto, is that you have much more room on the firewall to play with boosters and hydro-boost.

I agree with that trying to find something that not only works well in these jeeps but fits in the space required is a task in itself. I'm just running a pinto conversion and there still is quite a bit of room left on the firewall but its still hard to make everything fit just right. I'm using the throttle cable that was on the motor as for a gas pedal havent figured that out yet. The last jeep I did rebuild I think I used the gas pedal out of a cj7 but my willys still only had the original brake and clutch set up.

I used a set of hanging pedals out of a mid 90's mustang on my old jeep with minimal trimming and they have worked great. Just hung the XJ pedals in my new build yesterday and I think they are a little more simple but not as beefy of a frame. I have been using a single reservoir MC from a 55 ford for my clutch because you can go to any auto parts store and get it. Anybody else have any good ideas for off the shelf Brake MC, clutch MC and slave cylinder?

On my CJ2a that i put toyota axles under, i used the toyota hanging pedals.

You have to cut/bend/weld on the pedals themselves for them to sit pretty

I am running a XJ brake pedal with power booster but kept the stock clutch pedal with a AA chain adapter instead of the cable. I really like the chain set up and wanted to keep it. I had to mod the brake pedal to make it work but it turned out OK.

I have a 57 DJ3A converted to 4wd and was noticing your question about a gas pedal. I am not sure where mine came from since I did not build the Jeep but I also have a 1967 Ford F250 and the gas pedal assembly in it is very similar to the one in my Willys, it is a cble set up and may be easy to adapt and I am sure you can by them on line or from a Ford dealer if you want new or a junk yard if you do not mind used. 67 to 72 are all the same. I also have the AA chain drive for my clutch wit the stock pedal and it works OK as well but I have considered a change so that I can add power brakes. A little extra stopping power would be nice at times. Good luck interesting thead.

Time to bump this to the top as I am coming on this now with my beater jeep. They now stopped making XJ brake pedal assemblies, so what now? I considered keeping my stock one but I am not sure if thats better than the hydraulic. I like simple, and frankly hydraulic is very simple.

I read the advanced adapter pedals do not work for disk brakes?? And I am running front disks.

So what now? I have to buy wildwood? Or get lucky and find a XJ pedal pack from the junk yard?

Also on the brakes, what are you guys doing for a master cylinder? Just a single chamber or a dual? Does wildwood off a dual with the kit? Otherwise how would you make the proportioning valve work, and which one to buy? I was looking at this one:

JEGS Performance Products 63025 JEGS Adjustable Proportioning Valve and Distribution Block

But it is almost as much as I bought this stupid jeep for. Any help appreciated.

What I am thinking of doing is this.....
Buy this kit - http://www.bryke.com/Wilwood_340-395...Pedal+Kit.html
Buy this proportioning valve - JEGS Performance Products 63025 JEGS Adjustable Proportioning Valve and Distribution Block

And then buy the residule pressure valve I need (I don't know if I need 10 PSI or 2 PSI????) And run my setup like this. It will not be cheap but with XJ pedals being gone I am thinking it is my best option. This will hook up my 350SBC/T-90/D18 combo. Sound right?

I also used an XJ pedal set, but I cut and shortened/ rolled them upwards to make them work a bit better with the angled toe-board on a flatty.

Pics in my build thread.

I've been looking into this as well. I've pretty much settled on Wilwood since you have an individual master for the front and the rear separately. It also lets me split up the clutch and brake pedals so I can get my steering wheel in between them.

I've got an XJ pedal set if you are interested. I can't use it in my setup so It's pretty much up for grabs.

This is what I'm currently saving up to buy.

Late 70s datsuns have small brake boosters and a fairly beefy pedal pack. Modification will be necessary
