More brake disc problems

I had my brake disc and pads replaced under warranty at around 3300 miles as they were warped. I've now done 8000 miles and have been noticing a slight pulsing again over the last month or so, I mentioned it when I had my 7500 miles service and the dealer checked it and confirmed it was juddering. They stripped and cleaned everything and said it seemed better but the pulsing is still there and getting more noticeable.

The dealer said it would be no problem to have it replaced again and I'll be putting in a claim, but it seems excessive to have had two brake discs go in that mileage? Especially as I am not heavy handed on the brakes at all, in fact I use mostly gear and engine braking.

I know a few people have had their discs replaced but has anyone else had two go?? I asked the dealer if the discs were inferior or budget and he said not in his opinion - so I'd love to know why this is happening!

If I remember correctly, they insisted on replacing your pads too, costing you a good bit out of pocket. I have some pulsing too, but I'm thinking when the time comes I'll look at the aftermarket rotors. Interesting, Google turns up a ton of hits when you search "Ducati brake disc", there are posts all over the various Ducati forums complaining of warped rotors.

I had the pads done under warranty too Sarah so didn't cost me anything. I'd like to know why this seems to be a fairly common problem. If it goes again I'll look into a different type!

Lately I've been noticing a pulsing when coming to stop...

I hadn't paid much attention but maybe something I have to worry about. It must be something to do with the Ducati discs!

I'm glad it didn't cost you littleowl, hope the shop gets to you right away.

I had my first disc warp at about 2,500 miles. These were pretty gentle miles running in and then a few trips out. I had it replaced after I got back from my Morocco trip at 7,500. It's now up to just over 8,000 miles and despite some very heavy use at Brands Hatch is still spot on. They replaced my pads as well under warranty, not bad after 7,500 miles use!
It may be you're unlucky, or they're just cheap rotors. I think the latter!

those discs must be pretty expensive when out of warranty even when quality does not seem that good

I've been noticing it at low speeds as well. It's definitely something I plan to bring up when I bring it a dealership.

Apparently new ones cost around £200 so you would think they would last more than 3-4k miles with light use - mind you I don't suppose the price means anything if Ducati prices are anything to go by?!

Hello

One thing may cause a feeling like disc warping : if the parts that hold the disc on its support are not free, then the disc may seem to be warped.

Before going to your dealer, check that each of these parts is moving or not between the disc and the support. When one can't move, just put a tool in it and shake it until it moves. You can also inject some degreasing product to free them.

I experienced sometimes this on different bikes and freeing these parts solved what seemed to be disc warping and was just a bad positioning of the disc on its support.

Brembo probably sell them to Ducati for £20 to £30 - the rest is mark up..

I've had two different dealers check my brakes and both have confirmed the disc is warped, on two separate occasions. I appreciate what you are saying but I would have thought the dealers would check for that.. :ambivalence:
