I heard a noise that sounded like the brake pad warning tab rubbing. I removed one front wheel and caliper and checked rotor an pads, they were fine. I had to press in the caliper pistons to make installation easier. Now it feels like I have air in the system though I never opened any brake lines or hydraulics. I check for codes and got a C0265 indicating an ABS module problem. Would a bad module cause it to feel like it has air in the system? The noise seems to have disappeared. Rear rotors and pads are new. Vehicle is a 2003 S10 crew cab 4wd.
