Hello!

​​​​​​I have a Honda Accord 2009 with 130k km on the clock. Yesterday when I stopped at a red light i smelled a very intense brake smell, so easied it home and found out that the rear right brake was slighlty pressed ( alot of heat coming from there) i can only hear that the squeek when i slowly take off with no radio on.. I have read that this is a common problem, the easiest fix was the " springs" or "pins" on the bottom and top of the caliper mount. I got rid of all the crap that was there and lubed them up with some grease I had laying around, but the brake still holds, if i tap it with a hammer it comes loose a bit but still holds so there is resistance, when i start the car back up and pump the brakes, i can no longer rotate the wheel by hand until i tap it again.. What could be the problem?
