So the lining fell right off my pad on my rear brakes of my suburban. When I changed the pads I noticed that the piston went in pretty hard. is there really a good way to clean these up and lube them real well so they will operate smooth? I was told by a neighbor that he usually takes the pads off and get the piston to come out a good distance, put some never seize on it and then use the c clamp to put it back in place…hopefully that will lube it all up good. Makes sense to me. Trouble with my neck of the woods is we have a lot of salt/sand and grime on the roads in the winter and it gets into everything…creates quite a mess. Is this a good idea to do it this way, I'd rather not buy new calipers if I didn't have to.
