Changed my rear pads and rotors on my 2005 last weekend.

New pads and rotors went on. I noticed when I pulled the pins on each side the pins were bent. What causes this? The pads were just about down to the wear sensor when I replaced them.
I greased and re-installed the pins because I had to get the car back on the road but would like to order new hardware for both calipers with the pins, cotter pin and retaining clip.

Brakes have good bite and no noise or vibration. I do notice a slight grabbiness from the rears on hard stops. Almost feels like the ABS kicking in but I'm not sure if the bent pins are causing it. I never paid too much attention before on hard braking before I changed the brakes so not sure how it acted.

Beck Arnley and Centric make hardware kits. Anyone run into this?
