Question... the previous owner of my Ute upgraded the calipers to HZJ75 calipers and I brought a HJ75 Master cylinder would this possibly be the reason why the top of my brakes feel like air when I push it and get brake fluid resistance more half way through the pedal travel... been chasing this...
I've just started to replace my HJ75 front rotors and pads and turns out i've potentially got HZJ75 calipers... I went to install new HJ pads and they where a lot smaller got the part number off the old pads and ordered new ones which said HZJ75 which is a larger caliper and two larger pistons...
