[Fot] TR3 Brake restrictor valve

[Bill Babcock]

It's not a restrictor valve, it's a residual pressure valve, and I  
don't know whether or not Girlings have the valves in them, most  
Tilton M/Cs do, but you need to check. Especially if you use them for  
clutches since you absolutely don't want residual pressure.  If you  
have uprated axles you might not need residual pressure valves as  
much, since the pads won't be knocked back so readily by axle flex.

Generally people don't put residual pressure valves on drum brakes,  
though it's not a terrible thing. I had a five pound RP valve on  
Peyote's rear brakes for awhile and it reduced pedal travel without  
causing drag. I used 15 pounds on the front. I don't think there's  
anything on it right now, but it's at Tony's so I'm not sure.
