i popped the hood today and noticed theres a leak between the master and booster. the master i bought here off the board brand new, believe it was old stock. im thinking maybe a new booster and master is something i might be buying......again
im wondering if ONLY the master cylinder leaking could be causing the slow pedal return...i just dont want to have to pull the master, replace it, bleed out the system...only to realize the booster was bad too lol

I don't think the master cylinder could cause that, and I don't think it's air in the system. I guess I would be leaning towards the booster. Do you have an old booster you can try? You can change the booster without disconnecting the brake lines. Just unbolt the master and pull it forward enough to unbolt and remove the booster.....
