ok so my 1990 xj is a limited and has the most retarded ABS system that i have ever seen, the brake pedal has to travel 3/4 of the way to stop and i have to use a fair amount of pressure to do it.
the system is not working, and with the cost of new parts i dont want to start replacing wheel sensors or pressure accumulators or flux capacitors

so my question is =
Can i swap in a brake booster and master cylinder from a 1994 grand cherokee?
and if so, what else would i need to get rid of the abs system ?
