First, I'd suggest getting a second opinion from a shop you trust. You might also consider, depending on your operating environment, setting up a periodic caliper service.I recently replaced brake pads on the rear of my 19 Outlander SEL. The right rear caliper seized up. The mechanic says to sell it because I'd have to change the calipers on every brake pad change. He says no part store sells them aftermarket, and I'd have to send my truck to the dealership. That's a pretty penny. Any suggestions or advice? I cannot afford another vehicle right now.
