How hard would it be to convert a TJ to rear disc brakes?

[TerryMason]

I'm not ready to actually DO anything, but i'm curious how hard it would be to change over to disc brakes in the back.

Would this just be a matter of buying some rotors and loaded calipers, and bolting them on, or would I need a new master cylinder, rear axle, etc.

Do you guys think that the braking would be better enough for me to notice it?

Instead of just changing the brakes, you may want to consider to get a Honda Passport (look for the '96 model at your local yunk yard) D44, as they come with the Disc Brakes and Mini Drums for emergency brakes on the back... Of course, I dont know what model you have (YJ might make for an easier conversion), but JP magazine did it to a TJ.

I hadn't thought of the emergency brake. It's currently in the drum isn't it.

Right now, yeah, it's in the drum.

I would suggest you read from Stu....

this will give you an idea of trying it home brewed....or Tera-flex sells an all inclusive kit.

Thats a pretty interesting read. I'm not really upset with the braking of my jeep, at least not enough to do anything about it. I was more curious than anything.

Oh, in my case, I AM upset... Just not enough to do a rear disc conversion, but enough to change the front pads to Hawk pads and put new shoes in the rear! Hopefully this will give me a little more stopping power without having to go to rear discs. If this does not do it, I'll probably change the booster!

Find a ZJ in the junkyard, it should have all the rear disc brake parts to swap over.

The Honda and 'Zu rear D44's have disc brakes, but you end up with a 6-lug wheel pattern. Lot of trouble with axle brackets as well. A straight-up disc brake swap would be easiest.
