Before i took my 1990 JDM TT auto off the road 2018 the brakes were locking up big time under hard braking.I skidded 3 times and thought this scares the crap out of me!!!I have got uprated 350z discs,New pads,And bits and bobs from Concept Z to make them fit and hopefully in couple of months will dismantle and rebuild calipers,Use stainless steel lines and brakes will be better than before.Does anyone know if 1990 JDM came with ABS as obviously if this could be faulty i will pull ABS unit out and have it rebuilt or replaced.Cheers.
