Howdy,
I had my car on fluid change one month a go where they changed brake fluids witch were very old (in my knowledge it was DOT 5.1). There was some moisture over the booster and it was rusty all ready but I didn't notice any leak back then. Now I have notice that master cylinder is leaking between master cylinder and booster.
I found some thread where it was mention that if use DOT 5.1 break fluid this could cause the leak. Is that true and is it better flush brakes with DOT 4 before even try to buy new master cylinder? Or any other idea to get rid of this leak.
