Finally treated myself to one

brakes seem to becoming harder and to bleed since ABS came along
they seem to also like putting bleed nipples on the bottom of calipers
had a hello of a job simply putting some fresh fluid into the rear brake on the 899 this week

hoping the days of bleed, rinse, repeat are over

I've had one for years, and they are great for getting the brake to 90%, but I find you need to do a bit by hand to get them perfect.

One tip I'd pass on is to push all the pads right back into the calipers before you start bleeding (make sure they are nice and clean first).
It give bubbles of air far less places to collect.

Another trick is to bleed the brakes, leave it for a few hours, then push the pistons back into the calipers to push any little bubbles that have collected at the top banjo or master cylinder.  You need to be really careful though because brake fluid will fire out the reservoir at the top if you aren't careful.

They are awesome, BUT they suck so hard (fnar fnar) they tend to suck air from outside, down the thread of the bleed nipple, into the caliper and then back out into the tube so you think you are getting endless amounts of bubbles out when in actual fact, you aren't.

PTFE tape on the bleed nipples and agree with all of the above.

Last bit by hand.

I just use an large bore animal syringe from the vets with a bit of clear plastic tubing to the nipple. This allows you to push and pull the bubbles in the system from one end to the other to get rid of them .
Cheap and very effective.

About this size

not tried pushing pistons in, will give that a try next time

this is issue i had with rear caliper this week,
i thought i would be fine as didnt actualyl run the system dry
but the air was getting in from the thread when using me little bleeder!

when i get them apart with try this too

shame it doesnt sound like its going to give me quite the easy ride i hoped for
but if it speeds the process up even a little bit ill be happy

Last time I did the R1 from empty, I filled the reservoir, pumped the lever a good amount of times, bled the master cylinder then a load more pumps, pushed the pistons all the way back and then bled each caliper and then a load more pumps.

Took about 15 minutes to get firm pressure and then I finished it off by hand.

Komp why are you doing this...surely back to the Ducati dealer.????

[komp]

brakes were/are working fine.
I just like working on my bikes
and not going to take it to dealers every time I want to change the brake fluid
to me its part of the fun of bike ownership
next is a socket for that rear wheel, nothing i have is even close to big enough

[Alzo]

Fair enough...I just thought a fault had developed.

[Tiiimmmaaayyyy]

Changing the fluid? You've only had it 5 minutes
