I am testing out a 5th gen 3.0L car right now with the Z32TT calipers, worn skyline R32 rotors & Hawk HP+ pads. There is a lot of brake travel and it feels spongy. The lines have been bled, and it still feels this way. Is this a normal feeling for a bbk?

hmm to be honest no

umm.. hes right
rebleed everything??!?!?!!

after bleeding check brake bias if still the same upgrade master cylinder or you will never dry that sponge

well, 5th gen max has a different brake pedal feel... are you comparing it to 4th gen brakes? or "a lot of brake travel and it feels spongy" in general?

It just feels like there is a lot of travel and feels spongy in general, compared to any car I have driven including my old 4th gen.
