13" Rear Discs with BAER Brake Valve

[bry593]

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.

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.
