no it just runs the brakes and has a big ball that does things but otherwise very different.

transmission in the 4.0 xjs is top notch it moves the car in the forward direction and also backwards

A combination of pump, pressure accumulator and servo valve/master cylinder and ABS controller make up the system and a special bleeding procedure is required.
