Take apart the wheel cylinder and check that it is 1-1/8″ = 28.58mm inside. Clean the old pistons, hone or polish the inside of the cylinder with fine sandpaper. Wash clean with T-Spirit or thinner. If there is rust damage or cracks in the cylinder, it cannot be refurbished, in that case discard it and buy a new complete cylinder. If it is in good condition, assemble it with new gaskets that you lubricate with brake fluid.
