it probably is the master cylinder. That was what happened to mine and is not an uncommon thing when the bracket brakes in the clutch assembly.

 

does someone have a link on how to bleed the slave in the 8. Have had 3 and never had this problem, and I know how to search the forum, but I thought it may be easier to leave it to some of you guys who are more knowledgeable, that have maybe better links, that give better video detail for a first time slave bleeder on an RX8

 

just search “clutch bleed” using the search button at the top of the DIY area and read, read, read

 

Thats perfect. I’ll get to reading.
