I bought this K1500 roughly a year ago, its a 98 scsb 4x4 and did all around brakes when I first got it. The pedal never got "fully" hard but was drive able. I brought it to a shop, they put a new master cylinder in it about a month ago because mine was leaky, and still no change. There is no brake fluid leaks, all the lines look great (Tennessee truck, so very little rust). When they bleed my brakes at the shop they said they bleed the crap out of them and there was still a little play in the pedal. Im stuck here at a dead end, when I bleed the brakes this summer to try to figure this out, I noticed a little fluid would come out around the wheel cylinder bleeder valve as well, Im thinking ive got bad ones, but is there any way to be certain. The truck stops like it should once you get passed the play. Could it be a bad pedal assembly?
