It's apparent that is a problem with air ingress into the Calipers through the bleed nipples! Is there ingress through the nipples, the banjos or both and how to cure the problem is it a case of you nipples and banjos or put some ptfe tape around the threads of which one? Surely this should have been a recall by Ducati as its part of the brake System which I would class as quite important
When u say it's apparent? Do u mean you are having it? I have a squishy feel from mine when not used for a while, the first few applications are not exactly inspiring! But tbh I had the same thing on the Demo I rode and on my Daytona 675 (also ABS, different Brembo calipers) so I'm starting to think it's just a sucky feature of ABS. They are fine when worked harder
Probably doesn't help that my brake pins are going rusty! But in answer to the OP I would be pushing the dealer to check it. I had my Daytona back at the dealer 3 times for the brakes, and tbh they were never as good as the 899 ones. I know that some have changed the master cylinder also, like @ginge46 so maybe ask him for his opinion on the standard one as he has also ridden another one for a decent length of time (that was looked after by Ducati uk).
Compared with my 848 evo breaks the 899 are pants and yes I also have to pump them up, I did ask DM service department and he agreed that they do suffer with that problem but no recall
That's because the 848 Evo has absolutely eye balls stuck to the visor brakes! They are just so powerful and u only need to sniff the lever, definitely the finest brakes I have ever used! However the Daytona had the same calipers as the 848 Evo and the brakes were average at best so I really think ABS has to take some of the blame! Still. See if u can push them to do a re-bleed. Is your fluid quite dark? Mine is compared to the clutch fluid and I've only done 2k miles on the bike
Check your bleed nipple covers if you are getting air ingress you will have brake fluid inside the rubber covers. That's assuming you haven't spilt any in there before.
I read about the air ingress in the latest Performance Bike mag but lots of manufacturers use these calipers now so I would be interested to know why it's not a much bigger deal?
It's not. If air was going in you would have traces of fluid in the nipple covers. I've pointed this out to one fella at Hebden Bridge who was there on his 899. He said it's why his brakes were spongy and he read it in MCN as the reason. If air goes in, fluid has to dribble out when you brake.
Correct yeah, I'll check mine but I'll be honest and say that I think they would also get worse and worse and mine aren't.
