PROBLEM. R33 GTS brake conversion. hard pedal and locks up.

[creyes13491]

i just got a R33 gtst conversion for my s13 and now im having this problem with my brake pedal. it works fine for about the first time i start the car. until after about 10 minutes or so, then my brake pedal gets hard and i can barely press on the brake pedal. i already changed the brake booster to a z32 booster and the master cylinder as well to a bm50 master cylinder. please help. i really can't figure this problem out.

sounds like you have to adjust the pushrod in the booster.

^^ Bingo.
Take off the BMC and have a friend of yours press the brake for you as you adjust the tip of the pushrod.
