No more leaks
I have a 1970 Chevy C10 and my proportioning valve was leaking. I have all wheel disc brakes from a conversion I did years ago. I started noticing a stain that went from small to big in a matter of a week. I purchased this proportioning valve and so far problem solved and no more stains on the floor.

Works well in my car
I swapped a normal brake system into my 1994 range rover because the complex abs system failed on me. This proportioning valve seems to have worked for me so far. Dont forget to also buy the bleeder screw, its the little blue knob in my picture. Its not included. It replaces the white plastic piece during brake bleeding.
