And to the well said post above, one wants a bit of free play between on and off functions. As my first car mechanic said after he rebuilt my brake, "you don't want a wall switch for brakes". The slight bit of slop between the clutch/shoes and hub shell give you this.
As an aside-I worked on my first coaster brake after overhauling a number of SA AWs (and a S3C too). I remember looking at it and wondered aloud what to do. My boss said it had about a dozen parts (compare to the SAs with MANY more). And why was I hesitant.
Second aside- As to heat capacity goes just ask the Repack riders about that. Andy
