More Brakes - Dual Piston Caliper Mod?

[flint54]

Now that I'm nearing done on the rear disc brake conversion, I'm headed up

front next. Since I'm going to be changing out axles anyways (3.07 to 3.55)

I see an opportunity to upgrade the brakes. I've read the other forum posts on

using the TJ hubs and WJ knuckles/calipers. It seems do-able, but all write-ups

caution that the calipers will not clear 15" wheels without shaving. I'm not going

to change wheels, I just had mine refinished and like them too much. My questions are:

1) concerns about shaving calipers (assuming they don't leak)?

and

2) have any of you done this mod on your MJ?

 

Thanks!

While I haven't done it, I've been looking at this mod closely and share your concerns. I would definitely not shave the calipers, but would consider using just enough spacer I'd need to clear the caliper. But I don't like doing that either. I managed to find a substitute two-pot caliper with similar mounting specs to replace the old single pot caliper on my bike, but no luck yet for the MJ. :(

 

Also, some 15" Jeep wheels have a larger inside circumference than others. For instance when I installed rear disks, the Ravine wheels had enough ID to clear the caliper, but when I swapped to the turbine wheels I had to use spacers. The Canyon wheels wouldn't work either.

I am going with the Vanco 15" big-brake kit (designed for a 15" wheel) for my MJ's front brakes. It is 100% complete and bolt on. It also utilizes the dual piston brake caliper/pads and rotor from a Ford (98 Explorer, IIRC).

Yes, the Vanco is a great option, except they charge $750, plus $200 core charge.

Plus, the knuckles I would send them they would probably reject due to rust.

I figure I can score nearly all the necessary hardware at the JY for around $250 or

so.
