Brake Retainer on CC 100

[35boulder]

Now that I've got this tractor apart, when I reassemble do I need to do anything to the brake cup retainer? I've put a new o ring on it so do I just clean it off and replace? Not sure if there is anything else I need to do. Thanks

Here is the Brake System on the 100 per the Parts Manual.

Thanks for the diagram. I have this in my manual. Was wondering, does this retainer just get the o ring and a brake cup and then re-install? I have cleaned out the passage that the retainer passes thru, but I'm wondering if there should be "free Movement" of this retainer? Mine seems to not go in and out very smoothly. Hope this is making sense.

Hopefully you have the brake piston and cylinder surfaces all cleaned up, as smooth and shiny as you can. So there art two things in play when re-inserting the piston.

1. You want the "O" ring to slide in smoothly along the cylinder wall lest it bind and twist or break.

2. You want to prevent the piston sides and cylinder wall from building up rust on their surfaces.

Others may chime in with better ideas but I'm thinking a very thin application of petroleum jelly or aluminum anti-seize would do the job. Once all back together that piston only moves inward a minute amount when the brake is applied, and nothing pulls it back so there is no action to prevent rust buildup on clean metal.

As for anti-seize, I would apply it to the steel ball, and the pivot pin also when re-assembling.

Throw those parts in a can of vinegar overnight and wire brush them up nice and shiny.
Like Ironman said a little grease or similar type lube will keep them from getting rusty again.
Paint any exposed part of the assembly.
