Like most my braking is far from spectacular on my 88XJ especially with 33" tires. I find the brakes o.k. until I try to stop hard in which case the pedal bottoms out before I get any real good braking. It would appear as though I'm not getting enough fluid flow from my stock M/C. This was confirmed when I swapped to ZJ front discs as the ZJ caliper piston is larger than the XJ and the problem got worse. With the ZJ calipers the pedal would almost go to the floor before I got any substantial braking. I took the ZJ stuff off and went back to the XJ calipers.
So the fix...
I've got a ford E350 master cylinder which has a internal bore of 1.145" compared to the stock MC bore of .875". This should provide more than enough fluid for my stock system but I'd like to get as much as possible so I'll be putting the ZJ front calipers back on. It's also about time to change my rear brake cylinders so I'd like to upgrade to some larger units. The stock bore is 7/8" and I'm looking for some 1" or even a bit larger if possible. I found one website in which they used 1" bore cylinders from a 1972 ford pickup.
**Note.. I am aware of the potential consequences of keeping the stock booster and using a M/C with a larger bore. If pedal effort is unbearable I will more than likely swap in the dual diaphram booster from the 94 to 95 model XJ **
Does anyone know any brake cylinders that are larger than 7/8" and will bolt up to my rear Dana 44 backing plate?
Does anyone have any experience with running larger brake cylinders?
