Well my title here is the summary. I'll try to explain what happens when I drive. It rolls at idle fine but start moving quicker the car gets lumpy. If I gain a little speed and hit the brakes, there is a squirting/farting noise coming from I think the master cylinder. The brakes don't function well and it almost feels like someone cut a brake line or something. All the lines are fine, no leaks anywhere. Something must have gotten bent or broken. It's on the rear so there are parking brake shoes. Havent tested the parking brake. The car is a 2005 330xi. Please help if you can thanks.
