Decided to go for aftermarket Wildwood 260-8419 proportioning valves - 2 of them to keep the divided brake system( Frt left & Rt rear + Frt right & Lft rear)
Bought some Edelmann fittings: 4 ea inline tube conns, # 274000(10 x 1.0 mm Invert flare): 4 ea 3/16 invert flare x 1/8 NPTM 90* elbows,#122320: 4 ea 3/16 tube nuts, parts tore only had the long 3/8-24 nuts, # 121030, 1 ea 3/16" x 51" L metric line with 10 x 1.0 mm nuts.
Removed orig prop valve & replaced with 2 tube unions, 3/16 tube clamps. 2017-05-27-353.jpg 104.29K 23 downloads
Replumbed DS & PS brake tubing from firewall unions & added Wildwood prop valves on top where space saver spare used to reside.
Brake line from top of hill holder was removed & replaced with new line to prop valve. See diagonal line in front of booster.
Yes, some here disagree with using pipe threads in a braking system, but if you use a high pres sealant such as Leak Lock it will be fine. I've used this stuff for years for steam, hi pres hydraulic & other demanding applications & it will be fine. These Wildwood valves are 1/8 NPTF in & out ports. There are metric valves available but these are EU bubble flare only.
Test drove wagon after bleeding with initial valve adj at 4 turns in. Gave both valves one turn more & will see if more is needed. But for now the braking is back where it began after the rear disc conversion.
