Hopefully I can get some quickadvice. I got a set of new front caliper pistons, installing them and noticed the piston is slightly protruding. I am not sure if it's supposed to be flush with the rubber dust seal or if this protruding is correct. I just got them like this from npd a few days ago. I got one installed and when i spin the rotor it is def rubbing. wasn't sure if this would be fixed after i bleed the brakes. Ive attached a pic of the caliper.
