jhancock, thanks for the info. We pulled the wheel cylinder off this morning and what a cruddy mess it was. We cleaned everything up and found the parts almost new, no cylinder problems, even the rubbers were perfect. While we scout for replacements, we'll refit the cleaned up cylinder and see how it works. No leaks before cleanup, no leaks afterwards we hope. We will keep looking for rebuild kits as the aluminum pistons show some inside corrosion.

The Hancock NH Fire Department's oldest engine is a 1945 Mack EN330 Type 45 and is in the process of a safety restoration. Today we removed the front wheels and brake drums only to find the wheel cylinders rusted from lack of maintenance. We've searched for part numbers for the front wheel cylinders but have had no luck. Does anyone have that information? We’d like to replace them with new but could clean, hone and fit new plunger rubbers once we remove them to measure the inside diameter. Any help is most appreciated!

kscarbel2, thanks for the Motul hint. We plan to flush the whole system once we can move the truck to get the exhaust system repaired and will try the Motul.
