Vibration in brake lever when braking.

[langow]

Was riding this week (2017 Sidewinder RTX) and started noticing a light vibration ONLY when applying brake. At times it seemed to go away, then other times come back and get very noticeable. All seemed completely normal when riding and not using the brake. No unusal noises, etc. just the vibration I could feel in my fingertips when applying brake without locking up the track. Ideas? Do I have a drive bearing going bad, or? I did feel for any excessive heat around the brake disc, but noticed nothing.

Check your driveshaft bearing.

Check trackshaft for spinning inside bearing.

Driveshaft and bearing is toast as mentioned above.

Yep, sounds like your driveshaft and bearing are toast. The rotor binds up when this happens with extreme wear, and you start to feel it pulsating when applying the brake.

Ok thanks guys. Thats what I was afraid of, but hoping there was a simpler possibility.

You are playing with fire. I had this vibration one day and felt something a day later. I opened the side panel clutch side and saw a ball bearing from drive shaft bearing laying under secondary clutch brake assembly. Caught it in time. No major damage as I caught it when it popped out. 2017 sled. 7000 miles.

Proper maintenance prevents these issues.

I just replaced an upper shaft bearing on a 2020 Polaris with @3000 miles. Not just a sidewinder problem
