Just picked up a 81 k10 for cheap as i knew it had issues. I have done lots of work to it and to the point of being able to drive it. I got it good to go and the brake pedal was rock hard and i had to stand on it to get it to stop the truck. First thought was booster. I replaced the booster and it is better kinda. When coming to a stop it works as it should but if i am in line of cars and need to move up slowly, the pedal goes back to being hard again. And also, if i pump the pedal, it gets hard and stays that way for a few. I have replaced one caliper. I haven't checked for an actual vacuum number but at the check valve it feels like there is plenty. Im not sure if it is related but my back brakes dont work, at all lol. When off the ground, the rear tires turn freely. Any help is appreciative. The truck does havea 6" lift but appears the lines were extended
