I tried 3 other aftermarket parts and either they didn't fit or they leaked right away. This OEM part was totally different. It gave me good hard brakes and works great!
Only Good points of this caliper is it works better than the $50.00 CHINESE ones. This oem one slows the ATV down, but won't lock it up. Have bled all the lines, does seem to get a little better the more you use the brake.
