Napa should be able to cross those part #s. They are pretty standard #s in the parts industry, I've been selling parts since 1990. I got everything from AutoZone because that's the store I manage, plus discount.

Thanks Steve. The parts list and photos really help. I like the wheel cylinders with the brake line port angled. Seems like that makes it easier to get the S lines to work. I've read elsewhere about using a hole saw for the studs. I have a 20 ton press to push them out after cutting the swage.

Just thinking out load here....
I've looked at kits offered by Willys Jeep Parts, Woodys 4x4, The Jeep Guy and Herm the OD guy. It seems Willys Jeep Parts offers the most complete (and expensive) kit, but oddly its with non-self adjusting brakes. The others all offer self-adjusting with varying degrees of kit completeness. When I say completeness, I'm referring to the extra parts needed like hoses, mounting bolts, seals, longer studs etc. It would be nice to buy a kit that is really all complete. But then again, its not that hard to buy the other things as needed.

Jeep used "Z" tubes on all CJ wheel cylinders having angle ports.
All CJ factory 10" Wagner or 11" Bendix brakes used "Z" tubes. I find the "Z" tubes to be much easier to align and install than the the earlier "S" tubes. Poorly formed "S" tubes can be a real challenge (tight fit) especially when the cylinder ports are not angled. Edited by oldtime - 02 Mar. 2018 at 4:12pm |

Someone already did mine. I was surprised to find it since nothing else appears to have been modified, other than the alternator. Whoever did it used flexible lines and retained the original master cylinder. I believe someone on the list identified it as early '70's CJ Micah Yeah, I know, its up side down again.

Are you saying that the rear wheel e-brakes aren't strong enough to hold it but the driveline e-brake is? If so, that's what I was speaking to in my second paragraph (that you didn't include in your quote), that with the benefit of the axle gears the driveline e-brake might hold stronger. That's not related to holding all 4 wheels (the driveline brake has that same advantage whether the Jeep's in 4WD or not), but it could be an advantage of keeping the driveline e-brake. I thought you were saying that holding all 4 wheels from turning was important when just braking the rear tires would result in them sliding down the hill (assuming the brakes were strong enough to not let the tire roll). And rear wheel e-brakes will do that too (assuming the Jeep's in 4WD). But if that's not what you meant, then sorry I misinterpreted.

It seem a little funny that the pictures shown have more room between the backing plate and hose
connection and that the bleeder isn't closer to the hose connection too. Are these 10" upgrades or 11"? I tried to use one of those z-tubes and there was no way it was going to work, I had to end up putting a 90 degree bend right off the hose to clear the backing plate and a loop to connect to wheel cylinder. But I was using the older style 11" plates and drums off a willys truck.

The "Z" tubes were never intended to be used with the large hose guards that are mounted on the knuckle bearing cap
They used a different bracket that is mounted in place of the early hose guards.

So I better remove the Z lines off my 11 inch set up since they were not intended for the way I have them . But they work great. What do I need to do differently Oldtime?

You definitely need to get permission from Kaiser Jeep Corporation. Ha Ha! I expect that good brake tube fit depends on various concerns. 1) The type of wheel cylinders being used are either straight ported or they are ported at 45* angle. 2) Some wheel cylinders accept 1/8" flare nut style tube fittings while other wheel cylinder ports are fitted direct to the hoses. 3) Two types of Jeep bolt on" hose brackets can be used. The early guard type that was standard with "S" tubes and short hoses from 1945 CJ -1959. The guards were only used with the short hose configurations. Long hose configurations never used hose guards. From 1959 CJ-1971 Neither "S" nor "Z" tubes were required because longer frame mounted hoses attached direct to wheel cylinders. The "Z" tubes were only original for 1966-1971 CJ's having Dauntless 225 and 10" Wagner Brakes. Those 10" Wagner wheel cylinders required 1/8" flare nut fitting. The long V-6 Jeep hoses did not fit direct to the wheel cylinders. Otherwise the 10" Wagner hoses were long and so they attached direct to the frame. So a special hose bracket was attach on top of the kingpin bearing caps. With some re-arrangement; It's certainly possible to use the early type hose guards in place of the V-6 kingpin brackets and vice versa. |

Yeah Rick.
That's the configuration I'm using on my current (just started) build. It will have the 10" Wagners on it; partly because they weigh less.
