decided to tinker with the wifes 94 XJ country. The brakes are really soft. After bleeding the system they seemed to improve a bit but still feel dangerously weak. Is this common on XJ's? I was wondering if the WJ grand Cherokee master/booster upgrade would work in the 94 as described in the Tech article. I had a Gen 1 Montero for a while and became pretty handy but any tips would be greatly appreciated.
