I’ve replaced the rear brake caliper and a couple of the flexible lines in my 2004 Sportsman 500 HO (Early model) brake system. Replaced all brake pads also. I’ve bled all wheels until new fluid comes out with no bubbles, but it seems like there is too much travel in the brake handle. If I try hard enough, I can squeeze it to the handgrip. Brakes seem to work fine, but I’m afraid that when I really need them, it’s going to bottom out and not have enough brakes. There is no leaking, and the pull is consistent. On my other ATVs, I’m lucky if I can squeeze it halfway before it won’t go any further. Is there any adjustability in this brake handle/master cylinder, or should I just replace it. They seem very inexpensive on-line.
