This question already has an answer here:
I hope you can help me with this issue. My bike has Avid juicy 7 brakes, and lately both the front and the rear brakes are pressing against the rotor, which makes it really hard to ride it (feels like putting more resistance on a stationary bike). In the past before it got to this point the brakes randomly would be looser and then later more firm. Is it a bleeding issue or do you think that it's something else?
I would appreciate any suggestions. Thanks in advance!
