Thanks Gresp, Andy and Jeff. I do grease everything; it just seems like I have varied results every time I overhaul them - some work great, some not so great. i.e. those that work great I can get to skid easily. Those that don't work so great, I really gotta stand on it to get it to skid. I must be doing something inconsistently.
Yes, long downhills can be bad. Isn't that how the famous "Repack Hill" in Marin County got its name?
