I tried everything
- Reset pistons
- Reseat caliper position
- Credit card method
Brakes become very tight after a few squeezes
I went to the bike shop twice, they reset the brakes twice, wheels spin nicely at the shop but brake pistons stop retracting once I ride home, disc rub comes back again.
Getting tired of this. How do I tell them to check if the pistons are really working? And give me a new caliper?
