I just took my 2010 GS350 to Lexus Northlake to get new brake pads and they told me my rear caliper pins were seized. I understand this is a common problem but they are trying to sell me new calipers for $750+. Does anyone have a recommendation for a shop in the Charlotte area that would try to break that pin loose? The lexus dealer doesn't want to do this, they just want to sell me the new parts. I don't have the time or space to try and do this on my own.

Any help would be great!
