hi i know you guys are toyota guys but i have a 1985 nissan with the marlin crawler sas kit. i put the vented rotors and v6 brake calipers from marlin as well but the nissan master cylinder was to small so i had to pump the brakes to make them work. so then i went with a toyota power booster and the fj80 1" bore master cylinder. so now i have to pump them up three times before they work and th peddle is really easy to push so any info would be great.
