Thought i'd share.......
End of last week, my left rear caliper decided not to release after i took my foot off of the brake. I was doing about 70mph, but at least i was entering an off ramp by my house, so i only had to drive about a mile like this.
I let everything cool down (it was very hot, as you can imagine), took the caliper off (after much persuasion) and pressed the piston back down into the caliper.
Took a quick trip around the block, and sure enough, it froze up again.
I replaced it yesterday (a $165 part from the dealer and $65 for pads - i don't like rebuilt parts for brakes and steering) and it's as good as new - now i have three red caliper and one silver one. 152,000 miles - i hope the others don't fail now.
Has anyone else had this problem? It happened years ago on an old Accord i had.

 

yes, i and a few others have had it happen as well. You really should replace both rears and not just 1.

 

Chances are good that corrosion has entered the system, and use by mileage has caused the calipers to reach the end of their life
ALWAYS replace in pairs- 1 goes, the other follows because its been doing more work to compensate for the weak one.
While you are at it, check the wear on the front brakes- are the calipers working fully there?

I started with 1 bad front, and ended up replacing all the calipers and the master cylinder.
Prior owner never had the brake fluid changed and it should be done yearly after 3 years (normal service schedule per book)
