It was late when I tried installing some replacement brake pads, and for some reason the top of the replacement pads wouldn't fit properly into the channel that is supposed to guide the pads (lower picture). I didn't realize the pads were sitting too low after insertion due to an awkward angle and tiredness (and general incompetence). As result when I squeezed the brake lever the pin got squashed (first picture below).
Does this damaged pin warrant replacement? If so can this part be replace or does the entire caliper need to be replaced?
I assume brake force is not transmitted through the pin, as it is soft material, but I am not a brake designer so I am not certain. Once I figured out the pads were not seating correctly, I knocked them in place with a rubber mallet and ran the brake. Braking doesn't seem to be affected.
Here is the channel that the top of the brake pads are supposed to fit
