I took a 25 mile ride to breakfast this morning. After leaving, I used the cruise control than noticed EBD FAULT BRAKE FAILURE on the dash. I touched the brakes to make sure they worked, everything seemed fine the rest of the way home but the FAULT message didn't go away. What should I check ?

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
EBD fault message on my 2015 F3s. What is it?

IIRC, EBD is the 'Electronic Brake Distribution' system that allows the VSS & ABS to monitor the rotation of each wheel under brakes and adjust/balance the brake application both front to rear and individually on each of the 3 wheels, all in order to optimise your braking effort thru just the one pedal application. 
The EBD system is the bit of really smart kit that means you don't need or even actually want a separate brake lever &/or a brake circuit for the front brakes only, like you'll find on most 2 wheeled motorcycles, cos the EBD system does all the 'timing of application' and the 'balancing of front to rear and side to side braking pressure' thru each of the 3 wheels a helluva lot quicker and with more finesse than any person can, something that's especially hard to do for the 2 wheels up front, where each wheel might be trying to brake on surfaces with different levels of traction, and then that difficulty is further compounded by the rear wheel running in it's own track with a whole 'nother level of traction!
Without EBD, ie, when you can see that EBD FAULT BRAKE FAILURE message, you might still have 'normal' braking, but braking hard/in an emergency or even just gently on a poor or uneven traction surface could well convert your Spyder into a completely un-guided missile hell-bent on self destruction and intent taking you along with it! I actually tested the Spyder's braking without EBD (on a skid pan & under emergency braking conditions)... Never Again!!
I'd suggest that when you check your brake fluid (maybe just top it up just a tad anyway), you also check your tone wheels and each sensor/sensor cabling very carefully; maybe do the Brake Pedal Reset process as well (search is your friend for that) and if you can't resolve it thru these or any of the other suggestions you might get here, don't ride your Spyder until it has been resolved - I reckon that if you hafta travel much further than a city block to get there, I'd even push it or trailer it to the dealer &/or a helpful & competent brake specialist instead of riding (I'm pretty sure it's a Bosch braking system, so a skilled Bosch brake tech who's prepared to put up with/work around the BRP attempts to prevent anyone else working on Spyders should be able to sort it - we've got a few here in Oz who can/will work on Spyder brakes).
Good Luck!

Thanks for the info! I started it later in the garage and pulled forward and reversed it with no alerts showing. I'm going to clean the sensor and check brake fluid too. It just occurred to me. I was parked on an incline at the restaurant. Could that possibly of caused the brake fluid to register low enough to set off the warning?

The EBD function monitors all 3 wheel speed sensors. So, check them all. The brake fluid reservoir on a 2015 F3 is up front by your right knee, right? Your design of the brake fluid reservoir typically isn’t sensitive to being parked on an incline unless it is really, really, low. Next time this happens, keep the engine running to keep the warning active, and call up the fault codes. A lot less guessing that way. Don't Google the code, that won’t be accurate. Search for it or post it up here.
