What year? A lot of miles?
When were the brakes last done?

It happens.
It happens more often after replacing brake pads.
Caliper wears and sticks. Only real solution is to replace them or have them replaced.
The days of just slapping pads in are going away.
I've seen a lot of people try and just replace the pads and end up buying calipers.
