Yesterday I was doing my brakes but I ran into a problem with the rear Driver side Disk brake on my 92 civic, The Piston in the caliper was hard as hell to Screw back, I screwed it back in a few Turns but it got to a point when I couldnt Screw it in anymore even with the Bleeder open so since it was missing a mm or 2 to work, I just hammered the caliper back on to the bracket, after putting everything back on, I notifced that it was rubbing bad but I drove it for a while so it was rubbing less and less, How should I go about this cause I know it is rubbing cause the car doesnt roll on a smalll hill with easy. There is also another problem, the rear left brake is rubbing but the emergency brake doesnt hold the car either on either side.
Any help would be appreciated.

 

the E Brake can be adjusted...as for the rear brake...hammering it wasn't such a good Idea....you may need to replace the caliper.
