ok. So I was getting tired of the spongy pedal on my 88 C1500. Decided to do the RWAL delete and new stainless hoses. After bleeding the brakes the pedal was even softer than before. So I went and got a NBS master cylinder. Bleed the brakes again and it just as bad if not worse. I can’t figure it out. I noticed yesterday that on the proportioning valve there is a little bit of fluid coming out of where the rear plunger pin comes out. Could that be my problem? Also. I have a pneumatic bleeder and when I do the rear brakes I’m never really getting just straight fluid. I’m not sure if that’s just how drums are or if I’m getting that much air in the system. With the truck off I can get a very solid pedal with no creep. But with the truck on the pedal goes to the stop. I took this picture from someone online but this is the exact setup I have. Where I circled it is where the little bit of fluid is coming from. Please help!
