Brake proportioning valve applicability
The Sub's brake proportioning valve is leaking and I think this may be causing some weird rear brake stickyness. Found one on a parts supply website showing one valve fitting '81 - '87 full size GM's, 2 or 4 wheel drive, 1/2 ton to 1 ton. I assumed there would be different valves for different vehicles depending on size or capacity. They don't list a difference for pickups vs. Suburbans eithere.
Any differences?
