Had one brought to me with the front brakes locked up. Pulled them, and 3 of the 4 pistons were stuck. Anyway, I got them freed up, cleaned as best I could, bled, and reinstalled. Not a brake expert(obviously since I’m asking the question), but have done a bunch of them in the past.

My issue — is that they are tightening up, and I can’t figure out why. I’m guessing with significant riding — they are eventually going to lock back up. I’ve had them apart 3x now and am still getting the same result. Brake handle is tight. Loosen the adjustment nuts and it feels normal. A couple of pumps later — it’s tight again. Doesn’t matter how loose I set it. Anybody have any ideas here on what is causing this? I’m not to wits end — but I am at a loss.
