I've a few questions about the WJ front brake upgrade. My searches haven't yielded answers yet.

You want to stick with your stock 5 X 4.5" hubs to retain your stock wheels correct? But the WJ lug pattern is 5 X 5" correct? Stock XJ rotors are 11", and stock WJ rotors are 12".

So where can I find a 12" rotor with a 5 X 4.5" bolt pattern?! Can I just build myself a 5 X 4.5" template and drill the holes myself?

I understand that a JKS .25" spacer must be used when using the WJ knuckles, but are there any other spacing/custom touches needed?

Also, will the WJ booster/master cylinder be any upgrade for my '98 XJ?

The following applies to using the Akebono Dual Piston Calipers only.

I added 1/4" spacers betwen the knuckle and the caliper saddle to properly space the caliper over the rotor.

I'm running Ford Explorer SportTrac Rotors.

Do yourself a huge favor and order a set of TeraFlex Offset TRE's for your tierod and keep it OTK. you'll have to clearance the nut on the draglink TRE a little bit.

Depending on your wheel size/B.S. you might have to grind the caliper a bit for clearance.

HTH.

So are those the dual piston stock WJ calipers? Is that spacer the same as this:

So what's needed for the break setup you have?

WJ knuckles, calipers, spacers? What vehicle does the rotors come on?

SeriousOffroad

The spacers I mentioned are in addition to the Hub spacer.
Again, rotors are off a Ford Explorer SportTrac
Tes the Akebono calipers were stock on some model years, others used the single piston Teves calipers.

All that's need is the hub spacers, caliper spacers.

No need for the WJ knuckles, just the spacers?

Also, would the brake booster upgrade make a difference in my 98 XJ?

SeriousOffroad

Your kidding.......right?

Of course you need the knuckles.

No, you've already got a dual diaghram booster.
