Linked Brakes

[Haroldsenior]

Our LC has "linked brakes" and I find this feature an advantage.
I can find no reference, however, in the hand book nor on the Forum to answer my question: Why does the rear brake not operate with the bike on the centre stand (engine not running) when I operate the R/H hand lever? Is it part of the ABS?

In normal use the front and to a lesser extend the rear brake works together. The rear is independent in operation when the rear brake lever is pressed. The magic is that it is controller by the computer and yes part of the ABS.

In short yes it's the ABS.

Think of it more as a stability control. The system operates the brakes depending on what it's seeing from the sensors. ABS is far more than just stopping brakes locking these days. The ABS name should really be retired as it's really the least of its functionality on modern vehicles.

Harleys have a similar system which disables at speeds below 5mph, maybe the BMW system does the same?

Thank you gentlemen and it's so refreshing to receive sensible, considered replies to a question instead of what sometimes appears on the Forum.

Ah yes, linked brakes.
I remember them well after a little excursion in Cumbria last Autumn.

I was wondering about this when changing brake fluid. I had flushed new fluid through the front master cylinder out both front calipers, and through the rear MC out the rear caliper. Being also front to rear linked my thinking is there would be a line somehow from the front MC to pressurize the rear caliper, through a diverter or ABS controller which I wanted to flush fluid through. Squeezing the front lever while opening the rear caliper bleeder didn't push out any fluid. I tried again with the bike running but still nothing, the lever sent no pressure to the rear caliper.

This place looks very familiar so had to post....... Exactly the same happened with my mates Africa Twin without linked brakes maybe you should have been in enduro pro mode lol
Be aware this surface is very very slippy I could hardly stand up to get the bike upright there was two of us check out the green slime on concrete

The front and rear fluid systems are fully independent in the newer model(s). The linkage is done electronically in the ABS controller using an additional actuator on each line. There are no bleeders on the module like the previous system.

Thanks for clarifying for me yankee!
