Brake Bleeding on the F800 with ABS
Posted: Fri Jul 13, 2012 7:54 am
First foray into this part of the forum for me...
My brother has bought himself an F800S (it's rather nice actually), but he's recently been complaining that the back brake has very long travel and is very spongey. Obviously needs bleeding, but how easy is that job with the ABS fixtures?
I'm very used to bleeding up non-abs brakes, but my only "knowledge" of ABS systems concerns those fitted to the R1150 Series bikes (aka R259 oilheads). On these there's multiple ABS circuits, all of which have to be bled (as I understand it), and it seems to be massively complex an undertaking.
Are the "new" ABS units on the F800s the same? I know the ABS units have been upgraded massively in recent years - but they still work the same way, with multiple circuits etc? Or are they much simplified? Do they still have servo motors to increase the braking "power"? (I think this is where the multiple circuits on the old systems come in).
Any advice would be greatly appreciated!
