Do you know where your calipers have been?
These is a picture of my OEM front caliper. This bike has always been garage kept but never had the brake fluid changed. It sat for 5 years in the 90's and the last two years waiting for the progressives, etc to show up. If you have not rebuilt your calipers or are at least flushing the system every couple of years this is what the inside of your calipers looks like. Worse if the bike has ever been outside for any length of time. I almost was going get lazy and try and run these until Fall after the mods but needless to say I am glad I decided to go ahead and do the rebuilds. If you have not done yours yet or don't know the last time they were done and by who, it is time.

They live in their own little case, sitting right on my carb bench.

This post should be a sticky! Tearing apart the caliper is the only way to clean out the gunk, flushing doesn't get it.
Don't forget to change the brake lines as well; the lines develop scale just like shown inside this caliper and changing the line is the only way to get rid of the gunk.Ed
To measure is to know.

Brown Jello. Yuk. I went through the same thing with my 84 kat. Agree with Nessism - get new lines because that Jello doesn't wash out.

Just be careful of the oxidation, I was cleaning out a crusty master cylinder the other day and got a good wiff of the dust. I was choking on the stuff, its pretty toxic.

I rebuilt the rear on my GK and the damn thing still sticks. Must have a small 'pit' or groove that I missed.
Oh well off it comes again.

Zooks, I ended up using a dental scaler type pick with VERY light pressure in the seal and dust boot grooves ONLY to get them clean. After I got the main junk out I cut some narrow strips of the green scrubbing pads and used the flat side of the pick to put pressure on the groove area only. That and lots of brake cleaner.82 GS850L - The Original http://s224.photobucket.com/albums/d...ePics067-1.jpg
