A quick one here. Am doing my pre-winter sort out. I have bleed motorcycle and car braking systems, but not one which has ABS. I see the manual refers to digital Tech II quote "to confirm that the brake lines are properly connected and that air is adequately bled from the ABS system.

its the same as non ABS systems except that you are pushing the fluid through the ABS valves / solenoids as well and this can be felt as extra resistance when bleeding manually (using brake lever or pedal). The key to this method is not to let any air in the system. If air gets in the ABS system then you need to electronically bleed it.
I have done this on my mates ABS equipped Fatbob which with dual discs seemed to pull to one side when braking on the front and all is well now

 Get the dealer to do the ABS activate flush which rapidly cycles the ABS whilst changing fluid. 10 minutes, tops, depends on their minimum charge.

I have heard of BMW's where the ABS unit has failed due to corrosion , when the DOT4 had been changed by the owners , but the "old" fluid remained in the ABS circuit.

That's the big trailie GS things , ridden through streams etc etc

As with HD , supposedly the "best" way to change the brake fluid on ABS bikes is with the Dealer Digitech involved.

I've been thinking of changing the brake fluid on my 2013 Breakout , the front was changed by Frasers 2 years ago while chasing a warranty ABS brake light in the dash.

They did hook up the Digitech at that time , saw it done. Fault turned out to be a broken wire in the harness at the steering head after all that.

Watching this thread with interest I will be !

agree hilly.

OK. She goes to dealer to get looked at by the machine that goes "Ping"! Not worth leaving any crap fluid in while is trying to keep me alive.
