13" Rear Discs with BAER Brake Valve
After I installed 13" rear discs on my '71 C20 Chevy pickup, any panic stops resulted in the rear brakes locking up. If you ever had this happen when trying to avoid a wreck, you know why I chose to install a BAER proportioning valve, p/n 2000035.
https://baer.com/Baer-adjustable-pro...e-2000035.html Turns out, the valve wasn't enough. I adjusted it all the way out and still mildly skidded the rear tires. I swapped pickup to van calipers thereby reducing piston size from 2.00" to 1.75". Now the braking is excellent and all parts are genuine GM aside from the USA made brake valve. More info can be found at this video: https://www.youtube.com/watch?v=_WWka224rgs

TTT
Excellent explanation of the operation of the Proportioning Valve. I would argue that it is even better than the videos offered by most, if not all the people that sell those valves. Your pressure graphs based on your own pressure testing blew me away. Outstanding. I was surprised that the second knee point wasn't higher with the two valves in series. You missed an opportunity to explain how a Residual Pressure valve on the output of the MC would have eliminated any problem resulting from the installed height of the PV and plumbing. Lack of comments by others on this forum is disturbing.
