After a ride last month that took me down about 20 miles of gravel roads (thanks to my buddies "Garmin Gravel Finder" setting -- LOL) I found that my brake lever was very clunky. Stopping became very herky jerky and the lever was the opposite of smooth.

When I got home I washed the bike down and took the lever off. The dust from the gravel roads had gotten everywhere, including drying out whatever grease/oil was on the pivot pin. Cleaned up the pivot pin and the lever itself, then used some good old 3-in-1 oil. That put it back into smooth working order -- but only for a few days. Then the herky jerky came back.

Took it apart a second time and used some of my waterproof bicycle chain grease. This time it was smooth for a little longer, maybe 2 weeks, then back to herky jerky. I repeated this this past weekend and am now waiting for the herky jerky to return.

Obviously whatever they used at the factory was good enough to keep it smooth for 3 years and 12k miles. But I don't have a clue what to use myself.

Any thoughts on what oil or grease to use on that pivot pin to keep it smooth?

The pivot probably has grooves in it from the rocks. Try disassembling it and smoothing it out with some emery cloth.

I already checked that because I thought the same thing. Both the pin and hole it sits in are still baby smooth as far as I can by sight and touch.

Service manual says anti-seize.

Coincidence? Maybe the "herky jerky" braking action is not due to a funky lever pivot.

I guess if I paid more attention to the words in the manual rather then just the pretty pictures, I may have actually read what Vospertw pointed out....anti-seize. DOH!!

I'll give that a shot tomorrow night.

Thanks!

I would definitely give the pistons a good cleaning, you would be surprised how much it extends the life of the caliper if you clean the pistons at every oil or tire change, or both!

Is there any trick to cleaning the pistons / caliper?
