Everything was fine, all my battery problems were solved, the sticky throttle body sorted. It starts & runs ok now. Then I went to start the bike yesterday and the red warning light on the dash AND the brake failure light are flashing 4x per second.
I have checked what I can think to, ABS sensors, pads (replaced rears as they were low), fluid, brake switches etc, all seems ok. But the problem persists.
I turn the key, the brake servo whines and continues to whine until I start the engine, then no servo (and I guess no ABS), brakes are down to hydraulic pressure only.

Any thoughts before ANOTHER visit to Pidcocks? :nenau
(Which I'm not keen to make as last time they spun me a right yarn about arcing out due to swarf on my spark plugs and valves being way out and how the tech had stripped down the throttle body and lubed everything only for it to seize up again on the next ride, (and charged me £235!). I told them a coil was breaking down and could they plug in and tell me which one, but got a trip all round the houses only to end up with a coil, surprise surprise). :augie
PS, I have managed garages for years and know a yarn when I hear one.

Sorry for the long post, supposed to be going to Scotland :flag on it on Friday and have little time left to sort.
 
Is your rear brake light on, even though the brake lever / pedal are not engaged?

If so,check that the offside hand guard is not fouling your front brake. Also check that your rear brake switch is not being activated, either through needing adjustment or that a stone / crud has lodged in the switch, causing it to activate.
 
The first thing to check is that neither of the brake levers is catching on anything. The front brake is notorious for this if the handguard is slightly out of position. You seem to have checked everything else so if it isn't something catching (more likely at the front as the servo runs) then it might well be the battery voltage low, which is best cured by making serious progress for a couple of hours (or more:- you bought it to ride).
 
Cheacked all that, switches, sensors, fluid levels, pads etc.

Anyway, took to Pidcocks this morning and they diagnosed it as fault code memory full. Cleared codes, test ride, all ok.

I find it somewhat unnerving that brakes are able to fail due to a non-fault.
Anyway, off to Scotland, camping tomorrow!
 
I hope its the south of :flag you are visiting - quite a few main roads and sideroads closed due to snow - in Aberdeenshire / Grampian Mountain area

All's well that ends well.

It was probably just over-topping in the CANBUS juice reservoir :D

PS Unnerving, is camping in Scotland, tomorrow :flag :eek:

Aye, we're only venturing up to Biggar in the Borders.
Cool enough, reports say all the roads are open.
Temperature & rain doesn't us, just snow, ice & heavy winds.
Usually quite mild there this time of year with a clement -9 at night, nothing to shout about.
 
Groover, how are the roads ? Going to Glasgow-Edinborough in 2-3 days time, would be good to know, if you're still online.
Cheers!
