‘88 to ‘98 D30 brakes

[howeitsdone]

Looking at a front axle swap to a ‘98 D30.

 

What are the differences in the brake system?

 

Specifically asking about the brake pad size and rotors.

 

Asking because I purchased everything for the stock axle, but have decided to upgrade. I need to return all of those parts and buy new ones if different. 
 

Is there a post that contains a comprehensive guide to every axle and different nuances between the years? Not just the main differences, but even the smaller items that can or can’t interchange.

Your '88 knuckles will be desirable to anyone doing a Wilwood brake conversion, don't discard those. 

 

You will now order brake parts for a '98 XJ. 

 

Keep it simple and do not try to explain anything to any of the parts counter idiots. 

 

Axle shafts will interchange, steering and TB will interchange, brakes will not. 

 

Again, when it comes to unit bearings, keep it simple, '98 XJ. 

 

And your '98 should come with the larger axle shaft U-joints, that is desirable. IIRC..........

Thanks guys, good to know. Ended up not getting that axle since there was a front driver's impact at the wheel. With my luck I don't need to take the chance.
