I have 97 k1500 that I recently purchased. After driving it for about a week the brake pedal got extremely hard to push and the engine was struggling when brake pressure was applied. All signs pointed to the brake booster so I replaced it and it fixed the problem. Now I have a different brake related problem. Sometimes when I first start the truck, or if I press the brake pedal too hard when coming to a stop sign or light, the brake pedal gets stuck and the truck won’t move unless I put it park and turn the engine off and then back on. It makes a squeeky sound when this happens. I’m not sure if this problem is related to the brake booster, the sensor that is attached to the brake pedal or something else. Any help would be appreciated. Thanks
