I know the brake booster works off of vacuum, and my engine is now turbo'd, so now their is boost when it is under load. I put a check valve between the engine and the booster. The car has been sitting for 5 years (and yes I still have full brake fluid), so I'm hoping it's just calipers sticking. Now I'm thinking about running the brake booster pre-turbo since it's not working that well. I've been wanting to do a 7th gen rotor/caliper swap. What have you guys experienced with the brakes when the st204 is turbo'd? It should work with the check valve.

if you dont have enough vac to get good brakes, then you still have very serious air leak issues, or some other issue.
even guys running massive cams, dont report issues with braking like your having. do you have it connect like it is in stock form with the hardline along the firewall? -------------------- Former Team 5SFTE pro member ;)

Thanks, I found the problem already. I T'd off the vac line to the brake booster and connected a check valve for the other connection. I haven't gone to the trouble of switching the brake booster to a dedicated line yet, but I will be shortly. -------------------- -Jay
