Replaced the 20 year old brake lines on the 87 Graduate I purchased about a month ago, today. Convinced the spousal unit to assist in bleeding the system. Well after going through an inordinate amount of fluid I figured air had to be getting into the system somewhere. Sure enough, started the car had the spousal unit apply brakes and there it was...a steady slow run of fluid down the servo unit at the union of the master cylinder and the servo. Is this Alfa telling me to replace the master cylinder? Are there rebuild kits available or just go new? Car is very solid, very nice, only 54.6K on the clock. Thanks.
