Interesting letters from Steve & Martin in the last digest, and maybe I've
got the wrong end of the stick regarding the Sud limiter operation. But I'm
not sure about that, as I do know that when one of mine seized in its rest
position due to non-use of the car for ages, there was heaps of braking
available such that the rears locked up if you weren't careful. After I'd
freed up the limiter valve, this problem cleared, i.e. the limiter started
limiting when you hit the brakes.

Who knows!
Best regards,
Graham
