King pin 60 brake tech

[Gumbybronco]

I had those brakes on Ford Dana 44 knuckles with these 17" rims. This is the jeep that the calipers fell off of.

Seemed fine?

Thanks. My arms extend out the back as well. I was curious about caliper clearance.

I am seriously thinking about doing this because I just about to put new brakes on when I replace the front axle shafts.
Looks like this kit from PowerStop is reasonable enough then add brackets:

Speaking of residual valves, if you have the ever so slightly undersized master (not enough to change but just a little soft) would a residual valve help give it a "head start" and give better pedal feel?

I feel like my brothers JK with the J8 booster and 1 tons is 98% there but a tad soft.

Maybe call Trevor?

Fair enough, will do.
Thanks for sharing.

I did have a double sided arm, but again, D44.

Trevor's probably seen your exact combo as they originated arms for rear steering on PBB.

Just to circle back. I called WFO and they said no interference issues with my setup.
I ordered the WFO brackets and PowerStop kit.
Now I need to find a shop to turn my hubs.

I was pretty sure you'd be ok, but glad I am not on the hook.

Make sure you make your rotors hub centric to the hub flange

I figure if I give the machine shop the UFO machining instructions I should be good.

 

[Gumbybronco]

I got the axle (90’ Ford KP) back together enough to start on the WFO brake swap. I have upgraded knuckles, so I had to grind a bit for the 2nd bracket to fit. And then mocked up the caliper bracket. It fits, but is super close to the rotor on the outside. I’m pausing here and will get some grade 8 washers to put between the brackets.

 

[Grendel]

I wouldn't worry about it. Mine was that tight - do you have lug nuts on it?

Ok, good to know.
Yes, lug nuts are holding the rotor in place.

Will the 2010 or so dodge rotor and caliper clear a 16.5x9.75 4.25" BS wheel? Or are those only gonna clear a 17" or bigger wheel? Are the 4th gen dodge 2500 SRW brakes all same size?

I have a GM 60 that needs wheel hubs and brakes , so from what I have gathered I can use part of the dodge 2nd gen caliper bracket and weld that to the inner part of my oe GM brackets to make my own brackets for dodge brakes on the GM 60.

I'd say 17" bare minimum, with the right measurements.

That's a 17" rim, with the Dodge biggest brakes.

There are multiple size rotors, with matching brake abutments.

I know nothing about making my own brackets, I used ECGS's kit on Chevy knuckles and OEM stuff on my 2002 Dodge 2500.

3rd pic is smaller rotors. Same calipers.

 

[Alexis700]

Bummer, have a set of 325/85 16s that are going on that truck with the gm 60. It will eventually get 40s on 17s but will have to stick with the oe setup for time being. I need to get with the times and run wheels bigger than 16" on something I guess.

Ecgs is asking $715 for their brackets and a set of dodge calipers and rotors. I would say that $300+ is a little steep for brackets. But then again I do not have a CNC plasma table , so once you factor that in it is almost worth it to be able to bolt them on and go.

 

[Gumbybronco]

My OCD had me add the grade 8 washers even though Grendel assured me that it would work. Gap is more even.
I bled them a bit. I will bleed them more tomorrow to ensure that the system has fresh fluid - speed bleeders rule when you’re working solo.

 

[Grendel]

Looking good, and I get it.

Edit to add: Get a vacuum bleeder. Even moar better bleeding.

Circling back around this, GM put 16" wheels on the brakes that Gumbybronco installed.

I have used my friend’s vacuum bleeder and it was super easy. I like that speed bleeders also work on the trail.

Anything out there for DRW applications? Tow rig upgrade

 

[Malburg114]

Using branik legacy wilwood kingpin big brake kit with wilwood 4 piston calipers front and rear and looking for suggestions on a manual master cylinder and pedal length ratio.

Busted knuckle has a similar kit and suggests a 9:1 pedal ratio with a 1” wilwood high volume master.

Anyone have one of these kits and how do you like it or suggestions?

Sorry I missed this.

Playing with a Chevy 60 DRW and SRW hub, the OEM rotor spacing very close.

You may have to change up the knuckle bracket a bit, but should not be hard to get a bigger rotor on the back DRW hub, and that spacing is pretty much the same from all the folks converting DRW to SRW. It's not slip fit, but doable.

I think the bracket would need to be spaced back the thickness of the hub's brake flange.

Edit to add: Later model GM DRW is done the same way as the other OEM's. SRW spacing with a dually adapter. Could do that, too.

You would want 8:1 pedal ratio. BKOR said 190 is the target. 8:1 gets you at 194:1. 9:1 would be 218:1, that is a little softer of a pedal with more pedal travel. It does come down to personal preference.

Edit: on BKOR they show wilwood 6:1, 7:1 and 10:1 ratios, BKOR has their own pedal at 9:1. You could grab a BKOR pedal since it is steel, try it and if you think it is too soft you could shorten it a tad.

Thanks. I’m planning to make my own pedal but may start with the busted knuckle one.

Good call, just run all srw stuff and the spacer 2nd gen dodges used the same style spacer also.

Those adapters don't fit over a D60 hub. BTDT.

 

[YotaAtieToo]

I figured any of then would need some machining, or is there not enough material there.

Looking at them, there probably isn't, now that you say that.

Doesn't look like enough material to bore it out. Might fit over a D44 hub.

Aftermarket dually hub extensions tend to have a big enough bore.

Any updates on bigger/biggest OEM calipers for the job? (In a 17" wheel)

I know the 09+ dodge 2500/3500 calipers are what some of the kits use.

Ram 5500 piston size grows to 2.59".
