Brakes

I started asking around on forums about squeaking brakes and the best advice I received was to rebuild the calipers. So, they are off the bike and mostly in pieces. The pistons are stuck in the caliper. Likely the cause of the squealing. I'll need to use an air chuck to push them out then brush them up with some emery cloth to clean them up. Lube them up a little and put it all back together. With any luck I'll have a winner. While I'm at it I'm going to drain all the synthetic DOT 3 and use the traditional DOT 3. I bought the synthetic on mistake and didn't realize it until I started pouring it in. It seems really slick and I don't think that the master cylinder pumps it as well.
