The rear brake on my 1998 S1 is dragging. I assume it needs a rebuild kit.

1. Could it be something else?

2. I couldn't find a kit on the internet but I might have missed it. Suggestions?

3. While I've got it apart, any upgrades I should consider?

Suggestion...spray brake cleaner on the pucks. Use an old toothbrush and go around each puck to clean off debris. Spray again with brake cleaner and let dry. Brake cleaner on toothbrush to clean that.

Next, take that same toothbrush to apply brake fluid to each puck. Let sit for awhile. Then try to push the pucks back into the caliper. If successful, apply pressure to rear brake lever to push the pucks out again to the pads. Finally, once pucks are touching the pads, again spray brake cleaner to remove the brake fluid.

Done.

Might do to give Lance a call at St Paul H-D. A kit, or a place to get various bits might be available . . . . .

Like Two_seasons says. Or, IF you can work carefully, and IF you go into it knowing that if you mess something up you are in deep guano,you might consider a complete tear down and reassemble.

Before doing anything, is the brake lever binding? Is the return spring OK? Is the master cylinder OK? Is the fluid return port clogged?

Maybe a complete flush and fill with fresh fluid first and see if the problem goes away . . .

Hope this helps, Dave

I believe Lance has both kits listed on ebay.

When I got my 97 S1 I looked into getting some rebuild kits, and had a hard time getting them. I was told something for the rear brake didn't exist. I want to say it was a MC rebuild kit that you couldn't get. My front was the one having problems, the piston in the front MC wasn't returning, so I just had to pull it apart and clean it up as best as I could and put it back together with the original parts. It's still not perfect, but it works.

IIRC, the "unobtanium" rear part is the mount/port for the brakelight switch. It's a goofy setup that mounts the pressure-switch in the brake hose/line. But I could be wrong. Happens on a daily basis.

I looked into the rear brakes likes for a while because I need to replace mine eventually. I did see some people on the forum saying they took theirs to people who make brake lines and they were able to make the original brake switch fit into a custom line. In general though, it sounds easier(and probably cheaper) just to trade it in for a pressure switch banjo bolt and a normal steel braided line. I used one of those banjo bolts on a supermoto I used to have and it worked perfectly.

On my M2, the rear brake rebuild kits weren't available any longer, but I was able to get them for a KTM with a very similar brake setup, and worked great. I think I looked up a 96 620sx

I went to KTM parts when I was rebuilding my S1 forks and didn't want to pay $50 for some fork seals. It's nice having another manufacturer with some similar parts!
