i have a 1991 XJ Laredo with some brake pressure issues. i have no brake pressure from my booster and i am sick of no power brakes, plus i want to get it trail ready for the pipeline in Wisconsin. i cant figure out where or what builds my brake pressure because it doesn't have a regular booster and i couldn't find any other info in chilton manual. i don't want to go to the dealer so i was wondering if i have to go to the dealer or is there something that i dont know about it. please help here is a pic of my master cylinder.
