I see this alot in my shop. Tell your mechanic to pull the brake booster pressure sensor and see if brake fluid comes gushing out. I know this sound stupid but on this car specifically the master cylinder leaks into the brake booster. The motor then picks up the brake fluid thru the vacuum line...
Never go in dry the first time. I soak my bcg in mobil1 5w30 (personal preference) then even wet the feed ramps and inside upper before final assembly. Maybe overkill but its fixed every jam for everyone else who brings me their problem child
Well that was fun!! Glad to see everyone!!! Just a heads up there wont be another one till after the first of the year so everyone spend some time with your families and loved ones and I'll keep ya posted on the plans for next year.
