Mechanical disc breaks sticking during adjustment
To start, I want to apologize for yet another thread on disc breaks. Im new to them and found it confusing to piece together a solution from previous posts.
Anyway, I am trying to adjust my mechanical disc breaks so the pads don’t rub against the disc. My thinking was i should rotate both pad adjusters fully counter-clockwise until full clearance so i can then individually tighten each side until first sign of rubbing. Then, i would subsequently loosen until first sign of clearance. I would do this for both sides, one after the other.
However, when i loosen the pads after meeting initial resistance, i cant loosen them enough to achieve clearance again. It’s as if the pads get stuck hugging the disc. If I loosen the entire way, still rubbing, until i remove and reinsert the wheel again.
Has anyone experienced this before or perhaps have a hunch on what is happening here? Would be super appreciative of any help.
Thanks so much,
Reese

While videos are okay, sometimes it’s better to just read. I have the feeling that your caliper isn’t aligned properly. You shouldn’t adjust the pads independently but as a unit. The inner (fixed) pad should only just clear the rotor while the outer (moving) pad should have a little more clearance. Also make sure the wheel is fully into the dropouts before making any adjustments.
