I'm having a problem when I apply the rear brake...

Aren't floorboard simply early warning devices?

As long as you keep your feet up.

Just sayin'...

I thought I would report in and let you all know what has happened; both in the shop and once I got it back.

They replaced the rear wheel bearings and told me that they seemed good but might be just starting to go. I could feel the slightest grind in there while turning the replaced ones with my finger.

They also replaced the swingarm pivot bearings and realigned the bike. They told me the bike alignment was good going in, but the pivot bearings were dry and very sloppy. I checked out the old ones and I'd say there was an 1/8" front to back play and maybe a 1/16" side play in both of them... much worse than I thought when they described it to me over the phone. The indy mechanic felt this was our "smoking gun".

Nobody knew if this was the solution to the shudder problem, although the "clank" was gone under solo hard braking. The shudder only occurs when riding 2 up.

So Mary and I saddled up for a 200 mile trip this weekend.

The shudder is gone, the bike glides into the turns, I didn't get sex this weekend, and the braking is very smooth and postiive.

Remember this problem started out as, what can only be described as, a rear brake chatter. There was no shudder or vibration running through the frame. I started out replacing the brakes, rotor, master cylinder, rebuilding the rear caliper, etc. trying to chase it down and all the while it just kept getting worse.

So if you experience a chatter in your rear brake, especially 2 up, think about checking the swingarm pivot bearings.

Then, after you think you've thought enough, go ahead and check 'em.

I'm happy to see that at least one problem was worked out.......
