I'm from Boston. The car has 140,000 miles and it was driven very softly by an old man... the brakes hadn't been replaced in over 50,000 miles (according to the guy... who knows)... So when I went in to replace the pads and rotors I found the issue. So after heating with a torch and freeing the pin, I used a gun barrel brush to clean out the inside, I also degreased it, then refilled with grease, brushed down the pin with steel wool and it was looking fairly polished. Yesterday I drove around for ten miles or so on the seized caliper, I didn't know anything was wrong til I got out and the rears were smoking. Now I'm wondering if the caliper is working properly. Today I took it up to sixty (on the highway for about three miles) then I let it coast to a stop without using my brakes... I could touch the rotors, but they were warm...should they be cool? The reason I ask is because I want to know if those 'pin rods' are allowing enough of a reduction in pressure on the brakes when I release. I know the pads are always resting on the rotors, but enough to cause the rotors to warm??? Thanks for your help everyone and sorry for the long post..
