I bought two of the new front wheel cylinders for my 51 1 Ton when I was putting it together. After I bled the brakes I gave the pedal full force and the pedal slowly went towards the floor and I heard a metallic crunching sound. When I removed the front drums I found that the Huck thread on one of the new cylinder caps failed and stripped. Looking at it really closely I saw that there was a lot of clearance between the male part and the female thread and the whole assembly was much lighter than the original.
