I am in the middle of chang8ng the pads on my front brakes. The bottom pin was totally stuck. After lots of banging and cleaning, I have it moving back and forth about 3/8" and can spin freely. However, I am unable to get it to pull through the caliper. I am afraid I peened over the end of the pin. All the tutorials I read/watch all say the pins pull out easily. What can I do to finish this job?
