The MC is sucking air in upon each stroke.
Common known failure with all C4 MC's.

It maybe a common failure but I've never experienced it in 15yrs of ownership and 92k miles. Maybe it's in how I flush and bleed them.
Don't know. I learned on my 72 vett not to just push a lot of fluid through the system. And to flush every few years even if the pads are ok. I'll be doing that service again this fall. We'll see if my luck holds.
