Im just wondering if on a car with the power disc brake option if these are adjustible because the one end with the rubber nipple turns by hand and if so what way do I go to relieve or take away brake pressure and do they come already set when you buy one.It seems my brakes are rubbing some and I changed the master cylinder,rotors, calipers ,wheel bearings and greased pins and distribution block and brake lines.Thanks.Any help would be much appreciated since I want to get this fixed.
