Do break calipers need replacing?
I have a 2005 Ford Focus with 100,000 miles on it. When bringing it in to have the back break pads and rotors replaced, the mechanic said we should replace the caliper too. He says that the rotor is rusting because the caliper is not pressing the pad down so that it can scrape the rotor clean. He claims that without replacing the caliper, I will need to replace the rotor again when the new pads wear out.
