Deere 4420 slave cylinder rebuild

Anonymous-0 · Feb 26, 2013

Rebuilding the brake slave cylinders on a 4420 combine. Have honed the cylinders. Have proper kit from Deere to rebuild - cups, piston, snap ring, spring, and based which fits into spring. Have double checked kit part number. Seems like the rubber cup hardly wants to move in the cylinder. New piston fits properly. How tight should the cup be in the cylinder???? Should I hone it some more?? Maybe smooth it up with scotch pad??? Maybe it should act that tight. Any ideas? Thanks.

If you put them in dry they will be hard to move. Lube the cylinder inside with whatever fluid is used in the brake system.

Did you lube the cup, with the appropriate lube,
before installing?

I will try more brake fluid.

Remember those big brake shoe return springs? That is what pushes them back in. They will work fine.
