I have an 08 silverado and i just changed the stock front rotors and pads. i changed the stock parts because they are horrible quality. the pads had some life left but were wearing unevenly and had pits in them. the rotors had grooves cut in them after being turned by the dealership once. i went with powerstop drilled and slotted rotors with ceramic pads. the brake pedal was fine before but since them change it now seems soft and has more travel in it. trying to find the problem. anyone have a solution or had a similar problem after a simple pad change?
