suggest replacing seals around pistons or just free up/clean manually.

The rubber seals to swell over time, and eventually restrict piston movement.

What also happens is you can get a band of rust in the caliper between the dust boot and the piston seal. You have to pull the piston out to see it sand it or we give it a fine bead blast. That binds the piston up
