Have had my FD RX7 front Racing Brake BBK for about three years now.
Just did my first flush after the install three years ago. Also did rears and clutch slave.
Using ATE Racing brake fluid.

Only the old oil from the RB FBBK has some very small pieces of rubber savings in it. First time ever that I have seen this on any car that I have owned.

Has any other owners of this kit seen this?

Spelling error!

 

Could be your master cyl on it's way out I think there's a seal in there that could be where it came from pretty sure you had stainless lines they break down overtime too inside

 

Getting it ready for DGRR by any chance?
