ABS Failure!

[hojones]

Question, When the ABS has a problem doesn't the ABS light come on and set a code. I believe thats the way it's supposed to work. Maybe they are gonna try changing parts and hope they find it.

I am very comfortable with the principles of ABS in general from a hydraulics perspective but I wouldn't want to begin speculating on this.

I am very interested to know the basis used for drawing their initial conclusion of a failed modulating valve. Was it purely from observing you on the bike and drawing a conclusion or was there a fault code, or maybe a bulletin has been released? If it was a "snap" decision then it wouldn't surprise me if the change tune at some stage. I would certainly elevate the issue and demand a formal response from MoCo themselves as this is such a critical failure on a new bike!

Good luck and please keep us informed.

+1 on that!
Also when the ABS releases, the brake pedal does not go to the floor - you have a brake fluid or master cylinder problem IMHO.

Harley doesn't do well with new stuff,it takes them awhile

I want to see what the outcome of this is. I was told that if ABS fails you still have brakes. If not sounds like a big lawsuit waiting to happen.

I always figured brakes are the most important system on a vehicle, not being able to go is bad but not being able to stop will put the hurt on ya

The system should be fail safe as far as the abs goes.. If the unit fails you should still have brakes front and rear.. Im thinking a failed M/C or a big leak but if you can pump it back up then it still has some fluid. They cant sell you a bike with abs that if it fails you loose braking but they can sell you one if the M/C fails you should still have the front or rear to rely on.. Kind of like a car m/c.. If it fails its 99% just one side be it front or rear so you have the safety factor of front or rear still working.. No nothings 100% so both sides could fail but back on the abs module thing if it failed you should still have full regular braking front and rear.. The have their heads in their asses at your dealer.. Parts changers......

Just as info there were no leaks....checked this myself from top to bottom. Fluid was also visible thru the sight glass of the rear master cylinder.

Would like to hear what the issue turns out to be.

Agreed. When I first read it, I thought, this isn't an ABS failure, this is a brake failure. If you pull the fuse, the brakes will still function. The fact that after you stopped and pumped your brakes, you had 50% rear brake...this an ABS problem?

Sounds more like air in the line or not enough fluid.
