Front brake cylinder

[briantheb]

Have always had a bit of an issue with the front brake.
Poor pressure and leaking reservoir lead to a replacement in  first year of ownership and period concerns have lead to regular checks of the front brakes resulting in new discs n pads and system serviced at 17+k miles.
Lever was still a bit soft with 2/3 pull in toward grip before firming up but returning to that at every subsequent pull.
Just got the bike out for first run of the year last weekend and lever comes right back to grips, pumps up a bit but after a few seconds it returns to pulling back to the grip!
Has anyone else experienced similar ?

Yes, exactly the same a couple of months back. I initially thought the master cylinder pump had gone u/s. My dealer collected the bike and bled the system. Left it in the workshop for four days and the brakes were perfect, better than they’ve ever been. They’re still brilliant! Nobody has a clue why they went off so quickly as they couldn’t find any obvious fault. I’ll be keeping a very careful eye on their performance over the coming months and hope they don’t do it again.

Thanks for the feedback.
I’ll get them bled and see if that works, seems strange after having all that work done by a Ducati dealer to have the system then somehow get air in it.
I had thought it must be the master cylinder as have had problems in the past and had heard I wasn’t the only one to suffer Master cylinder issues.
The new models come with a different unit which added to me concerns.
Will try bleeding them - thanks again.
