I just experienced a clutch failure and found out this was because the clutch master cylinder was never flushed out during fluid changes. My M3W has been serviced by a non-Morgan service agent, and I always asked for my brake fluid to be flushed out and changed thinking that all of the fluid would be changed because the clutch and brake fluid use a common reservoir. When my clutch failed, I surmised it was the master cylinder and ordered a new one. When it was replaced, black sludge was found in the old master cylinder, and we realized that it had never been flushed out. So my point is when you ask for a brake fluid change , make sure they flush out the clutch master cylinder and clutch related tubing at the same time. I never specifically requested that thinking all of the fluid in the clutch and brake system would be flushed out, but it wasn’t.
