8.8 Disc to Drums

I didn't find much on this but I'm thinking about swapping my 8.8 disc to drums. Mainly because the parking brake is crap with the disc and I don't think I will lose any stopping power with drums. I also think it will cost about as much for junkyard parts as the driveline disc brake setup. I was just wondering if I could bolt up a drum setup to my current disc 8.8 axle housing?

I believe yes. The housings are the same. But I think you'll also need axles out of the drum 8.8.

I converted a drum fox body mustang from drum to disk so I guess it works both ways. have you looked into a drive shaft/pinion E brake kit?

Some day I'm going to solve this problem. Why does the e brake work fine when the axle is in the Explorer, a bigger and heavier vehicle, but suck when it's in a YJ?

I wonder if the leverage design on the pedal is different?

In that case I'll snag some parts and see. I think the shafts are 1/8" difference in length but I think that may be negligible.

Yes but I think I can get all the parts for the same (or cheaper) price as the drums which are plentiful. I will also need to modify my NP231 output yoke and get a flange adapter for the driveshaft.

Let me know when you do. Are you still using the 8.8 e-brake or do you have drums? I put mine in gear and turn the tires into the curb because it makes me nervous even on the slightest incline. I can continue to tighten the e-brake tensioner but I think it's a losing battle.

I have not had that issue of the Ebrake. Either with a TJ or YJ. And I like to stop on steep drops and inclines.
I reuse the stock explorer cables and splice in with the jeep stuff.

Marking this for later since I sold the last jeep with 8.8 and will see how the next time goes.

It's the tires I think. Most people doing this have 35's. I left the discs in my 8.8 but completely gutted the Ford parking brake system and cables. Went with this. I used an overhead garage door cable pulley on a bracket welded to the side frame to turn the pedal motion 90°. Now it's 4.88 times (axle ratio) as strong as anything at the wheel. It's a Tom Wood kit.

Im frowned upon in the 8.8 swap world because I purchased mine out of a 94 (with the drum brakes). Regurding the stopping power I would be surprised if you louse any. When I first drove with my 8.8 compared to the stock D35 breaks it was a huge difference. I haven't yet set up my e-brake (Florida is flat anyway). for now I just carry tire chucks whenever Im parked on a hill.

Don,

How much did that set you back, if you don't mind me asking?

Here is the kit I started with. You need to have a flange type t-case output, not a yoke. I already have the flange style with my Tom Wood driveshaft and SYE kit. You also might have to fab the mount part on your own. In my case, the two black arms (one visible) were fabbed by me and welded to the rust colored round bearing holder of the SYE. I've had this in service for 8+ years I think. It has huge holding power, more than any other parking brake I've had on any vehicle.
