QUESTION
How do I get stuck pistons out of the calipers on my Sunbeam?
ANSWER
Stuck caliper pistons can be removed by screwing a grease fitting into the cylinder inlet and pumping in grease. This will pop them right out. One piston will pop before the other so I hold it with a couple of clamps until the other one pops.
