I have a 2005 with 150,000 miles. The front calipers (4) cylinders stick. Best thing to do is replace them with new or rebuilds because even though a good mechanic can free the old ones up, they will stick again.
Save yourself a lot of time. Don't "free" them yourself. Buy new/rebuilt
ones.
Cardone will work.
Don't forget NAPA.
I like NAPA - especially their oil which is over here at Kelly's now and then.
I watched a good mechanic spend two/3 hours trying to free up the calipers so they could work. Puts them on and they stick again.
