rear brake is gummed up. i tried pb blaster, wd40, triflow. not budging. it's the one on the left, stays shut if you squeeze it. see how the spring is doing something strange.
i was going to dissemble the whole thing, clean and see if that helps. unless someone has a better idea?
idiot check: to dissassemble, would i unscrew those two front bolts in the second pic?
