I recently did a brake upgrade on my gts r32 to gtst calipers on front... brakes were oki before hand and freashly bleed.
I fitted new disc's pads front and rear. *no leaks of fluid or air getting into the calipers*
( i have converted my rb25de to a rb20det if that somehow can be a issue)
I re bleed the brakes twice properly and the pedal still sinks to floor and i have to pump it up to get them stiff and soon u move or start engine it sinks again ..
thinking maybe a vacum leak but not to sure ;/ everything is in the right spot and that .. kinda shitting me ... or maybe booster.
any advise will be good or anyone had this issue . thanks alot
