Yes brakes are offten overlooked. Calipers may not fully release and the pads drag. You yourself should be able to push and pull your truck on a flat surface with the trans in neutral and the e-brake off. Something else that happens is the metal clips on the front pads break off, get caught, and they dig into the rotor causing performance and braking problems. Replace them with stainless steal ones, problem solved.
