Release friction between brake pads and rotors
I do not believe that is possible, but if you are getting noise or grinding, it might be time to upgrade to a new set of brakes. Or possibly regrease the back of your pads and clean rotors with brake cleaner.

They usually barely touch. This is normal. If you are getting a lot of drag, you might be able to remove the calipers and clean where they slide and put a little brake grease on that area before reassembly.
If it is just one, you could have a sticking piston or internally collapsed brake line holding pressure on the piston.

The pads need to "float" over the rotors.
If they don't, the caliper slider bolts are usually the culprits.
Remove the caliper and service it by cleaning all the crud and brake dust etc from it.
Replace the caliper slider bolts and the rubber gators and metal sleeves that run through the caliper and make sure you regrease them with the white grease supplied with the caliper slider rebuild kit.
Clean around your caliper pistons making sure the rubber protecor boots are not
torn etc.
Replace the anti-rattle clips if they are badly corroded/oxidised.
Re-assemble and put a smear of grease on the back of your pads to stop them from squeeling and test.
Hope this helps?

Dont forget it could be a sign of bad flex hoses....the lining of the hose collapses, which doesnt let the pressure relieve itself from the caliper when you let off the brakes...yours might be starting to go bad...

More than likely, the caliper seals are worn out or the pistons in the calipers are sticking. I would simply replace the calipers with re-built OEM type calipers and call it good. Also make sure all the hardware for the pads in the caliper is properly lubricated. This means the BACK sides of the pads, the retaining springs and clips that hold the pad in the calipers.
The idea is to make sure the pad moves back and forth in the caliper freely, with NO binding or sticking.
Hope that helps.
