Rear calipers seize, they go bad by rusting in place, and the rubber parts age.
Re-honing the bore is possible to a small degree by hand, after prying them apart. A rebuild kit for the rubber parts costs only a few dollars.
However, the process takes hours of a mechanic's time. I suspect you haven't done it yourself, or you would know how tedious it is.
Alternative would be a rebuilt caliper, which in my opinion is one of the best bargains in the automotive industry. Some are under $75....not a big
deal compared to the shop time it would take, and they are rebuilt better than by hand, especially the honing and electroplate.
This summer, I did 2 brake jobs and another full bleed all on German cars. Went through over a case of brake fluid. It's a piece of cake if you get
the hang of it. I can do better work myself than a shop, where they just slap it together with either crappy cheap parts, or overpriced oem parts. I
get better than oem for less. I did my front Mercedes for $45, German BOSCH rotors and English EBC pads. You just have to shop.
