- General Brake Pad Replacement Suggestions
- 2013+ (Gen2, Gen3): Try to not use synthetics pads or "sintered", but organic or semi sintered ones.
- Sintered are better for very aggressive riding/braking, but are generally noisier.
- 2012 and earlier (Gen1): Keep the sintered pads
- Brake pump is very weak on these models; you need all the braking power you can get in spite of noise.
- Sand the pads.
- Grease the back of the pads lightly with ceramic grease (copper grease can interfere with ABS sensors).
- Check caliper position.
- Check caliper springs, if any.
- Check the wheel for trueness.
- Sand the disk; it could have lightly crystalized.
- Make sure all the bolts in the system (including wheel) are properly tightened.
- After all of this has been preformed and before riding, clean everything exposed to dirt/grease with isopropyl alcohol
- When riding again, try to not brake very aggressively the first 20-30 miles.
