Resetting Proportioning Valve - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Daddy Brim** · 05-29-2011, 10:16 PM

I guess I lost my rear brakes a short while ago, as the result from a bad wheel cylinder. I knew that I needed new shoes, wheel at some point I broke a front brake line and the master cylinder went dry . NO BRAKES !!! not fun. OK I replaced all of the brake lines the bad wheel cylinder and the shoes. I benched bleed the master cylinder first next I bleed the front brakes and now I'm not getting any fluid out the back. A friend of mine told me I need to reset the check valve inside the proportioning valve. I can not figure this out, I need some help.
