Anyone converted to hydroboost on their first gen k5? I'm kinda thinking about going this route.. This weekend i went wheeling at hollister, and i was in a really hard spot, about to flop over and take damage between two trees when my brakes decided to intermitantly work. I think i was leaning so far over to the passanger side at one point that my master cylinder might have sucked air so thats why my brakes got crappy? i wouldn't think that is possible.. Somehow after 2 hours and throwing out my spare tire so i could drive the low side of my truck over it and not flop, i finally got out. maybe my master cylinder is going out? once in a while it will be like there is almost no brakes.. then pump it up once or twice and theyre back.
