I am really enjoying may new to me 2003 Ducati 999s Seems everything is in order, but have one minor thing.

I have noticed that upon stopping right before the bike comes to a halt, I have a slight pulsing in the brake lever.

The previous owner stated in his ad that the bike had "HH" brake pads on it but did not state what brand.

When taking delivery of the bike he told me about the pads and that they are hard on brake rotors but have great stopping power. Should have been a clue.

So anyway, called him back and he told me to just go over the rotors with a 180-220 grit aluminum oxide sandpaper. He told me that this is common with these pads and that the rotors are NOT warped. He said that sometimes when braking real hard and hold the brakes after stopping some pad material is left on the rotors and this causes the pulsing.Thinking the worse of course I snagged some almost new rotors off ebay and planned on putting those on.

I got nothing to lose so will give the sandpaper thing a shot. If not then will put the new rotors on.

I heard of this happening on some GS bikes but never on Ducati.

If I put the new rotors on should I also put new pads on. The pads on the bike look to have plenty of life left.

Anybody heard of this before?

Will Do...

I thought my front stand would be in by now, but with the holiday it will be next week. New Rotors will be in too. I am going to take the front wheel off and put it on my stand. I will check run-out on the rotor and rim. If that is good then I will lightly sand the rotors AND check the rotor carriers to make sure they still "float" as they should. Then put them back on the bike and see where I am. May just go on and put the new rotors on and clean the old ones. Never know when you need some spare rotors.

What causes the material build up is hard braking and then holding the brakes on the hot rotor. Some of the pad material then comes off and sticks to the rotor. Several of my BMW friends have had this happen on some GSs in the past.

Against my better judgement I am going to stick with the pads that are on the bike. They just have too much life left in them.

Success !

:dance:I did not remove the wheel and use the gauge just decided to give it a shot with the wheel still on the bike. Lightly sanded both sides of the rotors. Then checked each carrier and they were all free. then cleaned everything up with brake cleaner.

All is good now. All pulsing is gone.

I am about to spoon on new Michelin PP 2CTs and am going to put my new rotors on anyway, but will certainly hold onto these as spares.
