I am rebuilding the Brake Cylinders on my 40 Ford.
I do not drive the 40 very often and the Brake Cylinder Pistons seize up.
My question is: A) Can silicone grease be applied to the pistons without causing any issues/harm? B) Can a DOT5 Brake Fluid be used to replace a DOT3 Brake Fluid in the 1940 Ford without causing any negative issues? C) Would using a DOT5 Brake Fluid be a solution to reduce Brake Cylinder Piston seize up?
THANKS !!!
