Cleaning caliper pistons
Am rebuilding the calipers on the Dayton dual piston brakes. I have the pistons out and need to clean the scorched on brown stuff off. Any suggestions?

Just a few things to think about before recommending a rebuild:
The OP stated in a prior post that he cooked the brakes. This means the brake pads will start to flake off at the edges. Some would say the pads are no good now, others would say not to worry and they would keep on truckin'
The O ring has two surfaces, the groove and the wall it rides on. If the wall it rides on is scratched or compromised in any way (i.e has a set micro lip) the O ring will be short lived and will become a leaker. Also as the O ring is being driven into the cylinder it can twist on itself creating a weak spot. When a brake becomes a leaker it can not build up hydraulic pressure to stop, so in effect it also takes out the opposite brake on that line leaving the driver with only two working brakes on a heavy rig.
Given the vintage of the coach and the amount of use it is getting then I think rebuilding does makes a certain amount of sense. Why put on new calipers only to watch them once again rust and hang up from lack of use. Just keep a very good eye on things for awhile until you know for sure the rebuild was successful and the brakes are, and will, remain functional. MH isn't a car where you can pull/push the emergency brake if you have too and expect to stop.
