The Tusk Brake Caliper Rebuild Kits are a great way for you to keep your bike in perfect working order! They are made to OEM quality and contain all the rubber parts necessary to rebuild one caliper.
Installed it a couple weeks ago, so far so good. Also ordered a rear caliper rebuild kit by tusk a few months ago, no problems there either. Seems to be good stuff. I'm just an average older rider, not hitting huge jumps or crazy stuff though.
