After 23000 miles , developed problem with rear brake... Pads kept dragging on the disc... Not good news. This happened soon after servicing. Bled the brakes again, no joy, took rear wheel off and planned to overhaul caliper. Interesting Ducati do not supply replacement rubber seals for the caliper... So instead of spending £30 , you would have to buy a new rear caliper (£170 approx). Ducati please wake up ... This is a rip off. Transpires problem was with master cylinder... Now replaced and everything working fine. Just mentioned this in case other people have similar problem, in fact dealer was going to keep a master cylinder in stock since it does appear to be a problem. Disgusted that ducati do not supply replacement seals for rear caliper. The duke x
Well if the fault wasnt the caliper seals, why are you disgusted that Ducati couldnt supply you with any ? Its all about Brembo not wanting the public liability responsibility....funnily enough tho, try a KTM dealer...they seem to sell Brembo parts that Ducati dealers AND Brembo wont/dont......
Thanks for your reply. I hadn't considered the issue was with Brembo, not Ducati. The reason I wanted caliper seals was because I didn't know the problem was with the master cylinder until the rear caliper was off and I could not pump the brake to remove the pistons. I wanted to buy the seals in anticipation of this being the fault. Also, whilst everything was dismantled I would have cleaned up the caliper and replaced the seals to prevent future problems. As it happens, I decided to not clean the caliper in case the seals did get damaged and I would have had to replace the whole caliper.
I wonder if it is about public liability, or just brembo wanting you to buy another unit! I suspect the latter....
If its as good as the rear brake on a Sport1000 then I am not too sure why they bothered fitting them in the first place.
So what was the problem with the master? I have a dragging rear brake also, and was thinking as you were, that it must be the caliper. I'm trying to imagine how the master can cause this, it's just a simple pump. Piston blocking the port, maybe?
I didn't take the old master cylinder apart to find out specifically what the problem was. It is another unservicable part. When the brake caliper was off, there was no resistance on the brake lever and the piston in the brake caliper wasn't moving. Back break works fine now, so fault was definitely with master cylinder (£45 incl postage).
Some SC owners (mainly in North America) have swapped to 1098-style radial master cylinders (certainly on the front) & have claimed in improvement in feel. Might look at this if the need for a new master cylinder arises.
