my 5er started leaking brake fluid a lot. i will have to fill it about 3 times a week. i keep my eye on it daily so i dont run too low cuz i know how bad that can be. i finally got it on a lift today. i see that its leaking all down the drivers frame rail. it looks like it is coming straight out of the booster. as far as i knew there isnt any fluid in the booster(vacume i think) i think that most likely it would be the master but the front of the booster is dry. any ideas? i dont want to replace the booster if i dont have to $300. thanks in advance.
by the way its a 91 525i with the m50 motor if it makes any difference
