Just finished rebuilding the front callipers with new pistons and seals. Bled them 3 times including power bleeding but the pedal just won't come up. It feels like half the available pedal travel is in free motion before the brakes engage.
Car stops without pulling or locking up and the pedal pressure holds when stomping on them but I would prefer to have the pedal engage pretty much as soon as I hit them. Any suggestions on possible cause and what I need to do to fix it? Thanks |

I'll check it out. Are there any good boards for Vintage Racing? Or where Vintage Racers hang on the web? Seems like a really good Alfa following with VARA SoCal. They ran with HMSA when I was there. A GTA was hit by a 2002. It was bad. Hope it never happens to me...but it can. I made some friends in the Alpha community while I was there. Guy I went to SCCA Comp School with has the Barber Shop GTA. I even got passed by Jon Norman. There are some photos of the HMSA event on Sports Car Digest. One shot of me in the top of 8 @ Laguna.
