DeTomaso Mailing List: December 99, Message #222

     Tony,
     
     Steve's friends description doesn't match what I've seen over here. 
     That doesn't mean they don't exist. Sounds a lot like some thing I saw 
     in a book called a "Safety braker". Pre ABS device that was to reduce 
     lockup tendencies in a way like Steve describes.
     
     To tell the difference you'd have to disassemble it or review a 
     mechanical drawing of the internals or test them.
     
     Tomas

Tomas,
     
This is news to me.  How does one distinguish between prop valves that work 
statically, and those that don't?  This feature appears quite desirable. 
What is the mechanism that is deployed internally?
