I recently had the brake pads replaced at a local shop. The manager said that the inside pads on each rotor were cracked / crystallized due to high temperature. He said that all four callipers were failing by not always releasing from the rotors fully. I find this odd because the rotors were in good shape and did not require resurfacing. Is this a case that all four callipers are bad, or is this the result of old or cheap pads previously installed or something else? I purchased the vehicle used 6 months ago so I don't know the service history. The vehicle currently has 102,000 miles on it. The brakes always worked okay and only recently started squeeking before I had the pads changed.

First does it pull when braking? If yes replace front calipers otherwise I would replace with a good quality brake pad for that vehicle. Could be driver error with a lot of fast stops and city driving causing the cracked pads also. Let me know.

The vehicle brakes straight as an arrow no pull at all. There is no sign of any lock up anywhere.
