rubber or stainless lines?
I just upgraded the brake system; g60 calipers up front and new stock rears on my 87gti. The brakes were pretty bad beforehand, and I cant tell if the pedal firmness is correct. I'm assuming with this set up and the same brake bolster, a little sponginess is expected? Any thoughts? The brakes have been bleed three times diagonally so far. The car stops fine, and the pedal doesn't hit the floor. But, I noticed the difference right away. My intuition is telling me its a combination of air bubbles and needing an up graded bolster.
I love haters...motivation
It might be air, but your brake master cylinder is probably tired. I think I'd have taken that from the g60 too, provided it fit
