[QUOTE="Denver_FJR, post: 1166142, member: 19217"] That's kind of strange and may indicate a problem. The rubber diaphragm in the master cylinder should allow the fluid to rise/fall while acting as a barrier from outside moisture, there should also be white plastic piece with a small hole in it that prevents vacuum lock/pressure as fluid moves in/out of the master cylinder. One item overlooked when folks replace brake pads, they compress the calipers but forget to removed fluid from the master cylinder. If the cylinder was topped off previously, it may overflow once the calipers are compressed. I'm guessing in your case, the master cylinder was simply "full up". [/QUOTE]
