915: my horseshoe spring advice was wrong?

Hey folks: Just wanted to eat some crow on the board. I recommended that folks grease up the horseshoe spring to keep it nice and lubed---I think now that I am wrong on this point.

Background is that I replaced/rebuilt everything from the pedal box back to the horseshoe spring: new bushes, cable, and spring. When I put the horseshoe spring on, I caked that bad boy with grease.

Now, about 2 months later, I have the classic "over the top" delay that is indicative of drag in the cable and a horseshoe spring whose individual spring layers are no longer sliding nicely against one another. To restate, the pedal will feel like it is hanging at the very top of its travel, then thunks into the correct, resting position.

I attribute this to the grease I put in catching dirt and turning the grease into more of a rough paste. Can't say for certain, but did liberally spray WD-40 on the spring and it feels like butter again.

So either the grease is a bad idea, or these springs may need regular attention/lube. In all events, I would consider some other manner of lubricating this spring instead of the heavy greasing as I had done/advised.

A good thread on this is http://www.pelicanparts.com/ultimate/Forum3/HTML/002604.html

How about a powder graphite?

Most are auto-lubed by leaky engines.
