    I'm running and building with Wilwood pedal setups and MCs for both brake and clutch. I know lots of folks like the power brakes, I'm not a fan of them wheeling. Lost power to many times and wanted strong manual setups - hence the Wilwood. I also run Disk front and 11" rears. Can lock them up fine and many folks think I have power brakes with the way mine are set up.

    Wife hated the clutch and how much it took to run it. That and the binding issues made going Hydro there a no brainer. I have both the Novak Push and Wilwood/Speedway pull slaves on my setups. Both seem to work fine once you get them together.

    Not cheap - but worth every penny.

    I’m in the same camp. Discs front, 11” rears with floor pedals. No problems stopping 33’s. Y’all never tried to roll down a hill with the engine off?

    I ran the wilwood pedals and master too. They did work, I just got tired of the pedal effort. What length pedal do you run? Are you running wilwood calipers too? My setup was dual masters (one front, one rear). GM 1/2 ton calipers in the front, 11 drums in rear. I thought about improving the manual setup for a while but went hyrdoboost and never looked back.

    If you are going to switch to boosted, one benefit to hydroboost over vac boost is that you do get one to two boosted brakes after the engine dies. But after you use the reserve pressure it is a very heavy pedal to be sure. Manual does have that benefit of always being the same and predictable. I am on 35s now and my jeep is not too light (3800 lbs without me in it) which is also a factor.

    The hydro clutch is a no brainer for me. I am currently running a speedway pull slave. Works fine but i do go through orings on those slaves. What life do you get out of yours? Mine is in a hot spot, insulation helped some but I have gone through 4 in 8 years or so.

    I'm running the standard @ 12" pedals with the 7:1 ratio. I also oversize the MC piston on a dual MC to get the good pressure at the wheels. Most are Jeep or Chevy disk setups up front with standard Jeep 11" rears. I'll be doing the GEO Tracker disks on the current build, so we will see how that works out. Organic pads are the best bet for this as well...

    Used to think EFI would help - it does quite a bit - it can/does still stall at the 'worst' possible moments. But then, that makes sense as everything runs fine at good angles, no bouncing, being in the right gear for the full climb, no rocks rolling out from under where you counted on it being for the tire... :banghead:

    Interesting, that was basically the set up i used. If I was going to keep manual I would have played with the piston size on the master to increase pressure a little. Like I said it worked pretty well, but I always trend toward more power, lol.I cant remember the master piston size I used. Sounds like you have a good formula worked out.

    What calipers are you using for the Tracker disks? Front or rear?

    I don't remember as I bought them over a year ago for the build shelf but I believe they are front - I'll see if I can pull them off the parts list out in the shop later in the week (recovering from surgery). I'm using the specs and parts from the Brennan Metcalf Caliper Brackets builds on his Facebook page.

    I was just curious. I was looking at those for my rear disks I am setting up on my 9 inch build, but they were a little thin for the el Dorado calipers.

    Hope you recovery is going well!

    I have Chevy truck discs on the rear to go with my El Dorado calipers on the J-truck 44. But I'm running 6 lug wheels.

    I wanted power brakes more for road use then trail time. The LS motor spools up quickly so I wanted to be sure the whoa matched the go.

    Just to throw this out there, you can make or buy remote fill kits for under floor master cylinders.

    I did just the brake pedal so I could add a booster. It wasn't the CJ7 pedal but it wasn't that hard. The hardest part is bracing the swinging pedal to the inside of the cowl. Hard to weld or drill or work up in there.

    Not bad. Mainly had to re-configure the brake pedal to get around the steering column.

    I'm running all stock non-power over the counter 4cyl CJ7 era stuff(to get the hydro clutch stuff). I took the firewall plate also to aid in placement along with the dash brackets to keep the firewall from flexing. The dash to cowl braces take very little modifying for the difference in column placement. A torch is needed to heat up the pedal arms for placement and to get full swing as the floor profile is different. I have the 76-78 CJ/Ford style disks up front and 11" drums in the rear along with the stock proportional valve. I believe the YJ brackets will work also but can't comfirm and all were P/B if you want them. The hydro clutch should work less the slave(internal vs external).

    If you want to stay under floor but get a dual cylinder set up with reservoirs you can mount on the firewall Richard is making them again. Very easy install. R&Ps New Dual Master Kit
    Old article but it gives you the idea. He's making them for Flatty's and CJ's as well as wagons and pickups. He can be reached at 503-504-7011 or RandPCustom4x4@outlook.com

    He does not have a website. He's a one man show and isn't terribly computer savvy. He was the one that engineered the conversion long before Herm. I know because I was peripherally involved. I put one on my '59-5 as a test so I could honestly say how it worked. Easy install. I had to reroute/modify brake lines, mount the reservoirs, and I think it was 3 holes I had to drill in the frame. Richard has it designed so the bracket is the template so no guessing where the holes go.

    When I rebuild the '5 it will get hanging pedals for basically all the reasons already mentioned.

    using all over the counter cj7 stuff makes it easy to find parts i bet.
