Trustworthy Mechanic for Brake Components Repair Estimate

My 2013 Toyota RAV4 apparently has rusted brake parts per a check today at dealer--but pads are ok(?). Looking for someone trustworthy to take a look and repair if truly needed. I'm from up north, so yes we get rust but replacing everything ($3k) seems suspect. I was just at dealer up north 6mths ago. Brakes were mentioned as something to look at in future but nothing urgent or serious.
