What Andre Jute said-- your brake needs grease. *Since that is a very

grease.


Occasional greasing is the only maintenance that roller brakes need,
but they really need it.


Nothing wrong with Shimano grease but we pump Lubriplate
130AA [1] in them with good results. 'Good results' means
regular customers for 12 years or so. Normal interval is a
about a year in daily use.


[1] only because we have it, with an injector head, handy.


I've used Phil's because that's why I had laying around. Worked fine.
Yearly interval is about right in the rust belt. Should go a couple
years down here.- Hide quoted text -

I have used aerosol spray grease, regular white lithium, phil's,
polylube 1000 and the special shimano grease. The main difference is
that the shimano grease is much less prone to catching on fire during
a long downhill on a hot day. I have also used wd-40, tri-flow, phil's
oil, and 3 in 1 when grease wasn't handy it they all worked as well.
Using oil rather than grease seemed to eliminate fade, but with a new
effect of causing a major spike in braking power when the brake got
really hot. If the brake is making noise it is a good idea to clean it
out before re-lubricating, as dirty old grease will build up in the
braking ring and degrade performance. The other source of noise is a
loose cooling fin/ring, and that can be solved with locktight or super
glue. If you still don't have enough braking power after re-
lubrication try using a longer pull brake lever.
