Well bugger me backwards.
After 18.5k miles, I've suffered the brake failures increasingly reported here.
Thursday am, fully packed and raring to go to Lands End, I hopped on the bike, started her up exactly as normal and the 'brake failure light' was pinging away like mad, as well as the 'hazard' light below it being on solidly.
The latter had been on for a week or two, I'd put it down to a Touratech LED brake light thingy I put on recently, but ther flashing light was new.
I turned off, counted to ten (just for a laught) and tried it again, consciously checking i wasn't anywhere near a brake just to make sure, but it stayed on and flashing.
Off I hopped, checked the rear bulb (though those symptoms aren't the smae...you still check it right?) and it was fine, but I changed the bulb anyway as I always carry a spare now.
No change- but I did notice i had robocop whine from the servo when trying the front lever, but nothing from the rear.
Up to Prestige, and they kindly changed the foot pedal switch after plugging it into the diagnostics....and after a couple of false starts where the light stayed on, it went off and I set off to Cornwall.
150 miles later, at afuel stop, the damn light came on again, so checked the bulb again, called Prestige who couldn't suggest anything more apart from maybe take it to Ocean Plymouth, an I set off to Cornwall again, gingerly at first.
I tested out what I had left, and it was basically full front action, inc ABS/Servo, but only residual on the rear, with no brake light.
I did the fords ride, came back through the rain (I did slow down to 100 though for some corners on the A30 as I knew my rear wasn't working

) and after a visit to Prestige's computer again tonight, I apparently have a wiring problem between the footpedal switch and the rear bulb, so the system's not setting the rear servo circuit.
I didn't turn up until gone 5, so that was all they could find out in the time- I'll check more tommorow to see if I've fekked up with my autocom instal (though that's a year old so I doubt it) and I'll see if I can track down the break in the circuit before giving it to Prestige again.
One thing I can certainly confirm though is that residual braking is total utter bollocks........those who know me know I'm 6'4" and a heavy bastidge, so I'm able to put a large amount of force through that foot pedal, but I can tell you now that what you get on 'residual braking' isn't worth calling braking......even at full effort, it just felt like dragging the rear a little round a corner.
I'll report back when I have a solution, but for now, I'm just glad that a) it was the rear circuit so i could complete the weekend without undue incident and b) that I wasn't moving when the thing failed
Funnily enough, there wasa nother chap in Prestige at the time thisafternoon who was talking about his brake failure he had in at the time...didn't get a chance to speak to him though.
Gotta add full marks to prestige as usual.....they did a good job of at least trying to sort me out on Thursday.
