Coach 1482 braking system is Bendix.  It has a Bendix PP-1 parking brake valve which was connected to the Bendix PP-7 trailer brake valve.  The swivel fittings were leaking and some of the 3/8" lines were bent with such a short run that they had a side load on the fittings causing leakage.  I removed the PP-7 eliminating a number of leaks.  The pneumatic lines are available for use if needed at a future time.  The tag axle brake Relay Valve looks to be a Bendix R-14, I installed a 1/4" Street Tee into the R-14 Service port for the toad brakes.  When the brakes are applied the line is pressurized and when the brakes are released the line depressurizes.  No buttons to push, nothing to forget.  The toad braking system I use is M&G 2.0 which operates the same as an Air Force 1.
