Hello!
I have a Honda Accord 2009 2.0 with 130k kms on the clock. Yesterday when I stopped at a red light i smelled a strong brake smell so I easied it back home and found out the rear right brake was slightly pressed. I read online that this is a common problem and the easiest fix was to lube up the "springs" or "pins" at the top and bottom of the caliper mount, i got rid of all the crap that was there and lubed it up with some grease I had laying around. The problem still persists, If i turn on the car and pump the brakes im unable to spin the wheel by hand, but when i tap it with a hammer it frees up but there is still some resistance compared to when I took the pads all the way out... What could be the problem?

Thank You!
