Hi guys, I have brake deposits or heat spots 1 1/2 inches apart all the way around my front rotor. Has any one else been successful at removing and fixing this? The shutter I get while barking some times makes me a little nervous to ride it hard in the twisties.

Regards Ray

Go to your local garage or parts store and see if they have about 4' of emery cloth. Gets old quick but I got mine cleaned up in about 2 1/2 hours that way. Looks like brand new now.

I put Lyndal Gold pads on from American Sport Bike and they helped dramatically.

Still not perfect though.

In the future, use the rear brake to hold the bike at lights, not the front : )

Ray - had the same problem on my Uly and discovered quite by accident that riding in very heavy rain (and using the front brake regularly while doing so) cleans the disk up as clean as you like.
The deposits on my Uly disk were so bad at times that the handlebars would visibly shake when braking. I switched to SBS Sintered and the disk now remains shiny - with 67,000km on it it is getting quite worn but the shuddering is long gone.

The best way to get the whole brake thingy working right is to do the following. This describes the front wheel only which is usually the problem.
If one changes the tires and the pads at the same time, it will all seem worthwhile.

1, remove wheel,
2. Remove tire.
3. remove brake rotor. Note the way the mounting hardware and springs come out.
4. Clean, smooth, rotor with simple brake hone. ($30).Putting the hone in a drill press and having a friend rotate it is the easiest way to go.

Be careful to clean the mounting hardware. New bolts are a good idea, and Chrome or stainless ones will look nicer.

5. Replace pads with Lyndall Golds. They work better and don't leave deposits. Note break in procedure. Available from sponsor American Sport Bike and others.

6. Replace tire with nice new one like Dunlop Qualifiers, Michelin Pilot Powers or your favorite.

7. Rock on!



PS: everyone has their shop manual, am I right?

You can get most deposits off using aerosol brake cleaner (Torco doa very good one)and some Scotchbrite. Emery cloth and honers may be too abrasive for what you want really.

Secondly, get rid of the OE brake pads, as they are the cause of the deposits being left on the disc. There are many aftermarket pads available that ofer superior braking performance and better heat dispersion than stock pads without leaving the disc a mess. We use Braking or SBS, but there are plenty of other decent makes out there if you can't find these in the US.

using aerosol brake cleaner ruined the finish on my black rims..... keep that in mind.
