Angry Loss of brake- Front handlebar

As I was backing out my K1200LT '03 onto my driveway (and slopes down to the street), engine off, I went to pull on the front handle brake, and there was no braking. I tried to push the back brake and it wasn't enough to stop the bike and it fell over on its side. I've never had this problem before with the front brake handle before. I know I have to have a forward rotation on the front tire to activate the ABS.
The dealer recommends a brake flush maybe thinking there is contaminate in the fluid. Any hints? Is this the route I need to take?
When I started the bike to leave, the braking system acted normal.

I've never had that happen on my 06 and I'm always moving it around without it running. Is your brake fluid low at the handle bar? Do you have original brake lines?

Re: Loss of brake- Front handlebar

The servo brakes are very hard to use with the key OFF, it only offers residual braking. Next time just turn the key and move the bike.

Re: Loss of brake- Front handlebar

Thanks for the reply, Troy. The fluid was low and a bit dirty so I'm gonna get the bleed. Yes, the brake lines are original.

JZ: Thanks for the reply. Until I can get this bike in for a brake bleed, I'm gonna start the bike up and active the ABS, then back it out with the clutch.

Re: Loss of brake- Front handlebar

You really need to consider changing the brake lines over to Spieglers... before you have real big problems. 🤔

I too am running 17 year old rubber brake lines. Any info on the Spieglers? Is there a "kit" for the LT on line?

I'll have to search Australia as the Australian Post Office is not accepting any parcels from the US at the moment. I have three parcels stuck in the Chicago Distribution Centre that aren't moving for this reason. The Australian parcel system is way overloaded from everyone shopping on-line during lockdown.

Speigler sells their kit directly or thru Beemer Boneyard. It’s a must for bikes as old as ours.

I have no idea as to availability down under, but I bought mine here. The main reason I used STG is that their price was comparable to other vendors, but they have the added advantage of including new banjo bolts color matched to the fitting color you select. They did send me two of the wrong size bolts and that took a couple of weeks to get sorted, but I was pretty happy with their kit overall.

Re: Loss of brake- Front handlebar

I replaced mine a coupe of years ago and from memory I got them off ebay. The kit was well made and everything was labelled so you couldn't mess up which line went where.
Gives you piece of mind and it's money well spent.

Oh and I never shift my bike unless the engine is running and I'm on it. I want maximum control over this beast.

Ordered the Spiegler set today from the US. The company I ordered through told me USPS will not accept parcels to Australia, but the company will courier them to Aus. for US$35.

Happy days.

Re: Loss of brake- Front handlebar

Voyager: My only hesitancy is the cost of the kit, and then the bleeding of the system through the ABS module. Not trying to be complacent and not dismissing your suggestion, but so far, I don't have any leaks on these lines and haven't had any problems on this system, yet.

The servo brakes will operate fully after the first self test where it goes from fast flash to slow flash. The lights go out after the rolling test of the wheel sensors and only take a few feet of movement. ABS is only activated when you are hard braking and a wheel begins to lock up.

JZ: OK.. Thank you for the reply. MY unsolved thought still remains is why the brake handle went full travel and loss of braking when I backed out. This never happened before and still wondering why. I'm now going for replacing the liners and have the dealer do the bleed.

Just so we are no the same plane here, when you backed out was the key on and the engine running? Was it key off? It make a big difference.

probably not what happened to you but a thought, I replaced the front pads and forgot to activate the brakes before backing out of the shed key off, same as you million miles an hour backwards no brakes engine off fell arse over tit backwards.... Laying the bike down going backwards is no fun. I never move it now unless the ignition is on.

Axle: Yea, I now have the key on as a minimum. I'm now starting the engine and using the clutch as well to slow the bike on my driveway on the downward slope.
