1150 brakes

Out yesterday on my 1150 gs and the brake failure light started flashing brakes still working so carried on after a bit lost back brake. Got back checked pads etc nothing obvious but the pump seems intermittent bike is 2003 with abs any ideas please cheers Steve

The dreaded servo

If the servo is intermittent, it may be on it's last legs.

I guess a trip to the diagnostic machine should give you a better clue.

They are expensive but removing it and going back to old fashioned brakes isn't. The servo brakes are very good, but I always found them unnecessary. I'm on non abs non servo brakes, they work just fine

I had exactly the same problem with my 2002 1150. In fact I still have the problem very occasionally now.
When it happens the back brake seems to go into residual mode but the front one works. If I stop the bike and start up again the brakes go back to normal.

I had a main dealer investigate and they could not come up with anything. Of course the problem never occurred for them when they tested the bike!

I have changed the fluid twice since the problem first arose and this hasn't cured it. The problem is quite infrequent so until it gets worse or something permanent happens I will live with it. Then I will take off the ABS unit!

Easy checks ...

... make sure your rear brakelight bulb is ok, not just that it operates, but that both filaments are intact; second, ensure that your handguards aren't fouling the lever because if it doesn't get full return you'll start getting warning lights.
