Default (ZJ disc swap) still running the drum prop valve?

Who has done the ZJ disc swap and is still using the drum brake proportioning valve and how did it work?

its time to replace the worn out drum brakes and all the rusty/broken hardware off this northern XJ... its a stocker with 235's......

Ive got everything from a donor for the disc swap except the proportioning valve and was wondering about doing the swap with out it and how they worked using the stock drum prop valve.

I can do the proportioning valve later if needed but dont have one sitting there and would rather go ahead and put the disc on now rather than put the time/$ into drums only to change them in a couple of months.

Be careful on slick roads, but otherwise, you should be ok. I know guys that do the swap and don't change the valve ever...

Didn't change mine, noticed a bit of drag on the rear brakes but stopped tons better than the drums.

You dont have to change the whole valve.. all you have to do is change the spring inside of it
