[Fot] Spitfire Slave Cylinder Vexing Me

[Mike Jankowski]

I never did anything with the slave or master since installing them 4 years
ago. No leaks anywhere. The only thing that changed was the engine, then
the problems started. So I'm going to replace all the clutch hydraulics and
that will eliminate all those variables.
