Thanks for all the good info. After opening the drums up, I dumped all the drap out and then reassembled. Iw ish I had of thought of testing the cylinders to see if both pistons actuate...oh well, next time I will think of it. The brakes, although only 1/8" of pad left, are working perfectly smooth. Since we heading into winter (really cold here) I will wait until spring to do the change. I was wondering if anyone could comment on the drums; i.e. if mine are worn down to 10.875" approx. shoulc I just go ahead and change them (I will verify with calipers before actually doing it) or should I just change the pads and hardware and re-use the drums and check them again in a couple of years? New drums are about $60 each.
