I recently bought a 2010 Silverado 1500 4.8 with almost 300k miles. Trucks runs smooth and has no issues or weird noises. Except the service brakes soon and my brake pedal is soft. I replaced the front brakes haven’t done the rear(have drums)I tried bleeding the brakes to see if the pedal would get stiffer but nothing... unless I did it wrong which I doubt it.
Plz help and it’s giving me that code.
Thanks guys
