No Rear Brakes !!!!!

Last Sunday I went for a lil ride, along the way I noticed that my rear brakes started to feel soft. After a few miles I had NO REAR BRAKES !! It was not that big of a deal at the time as I mainly use the front brakes. When I got home I checked and the rear master cylinder tank was EMPTY. As in bone dry !!! I never got an ABS light to worn me or anything .As I tore everything apart I saw a hole in the brake line just above the master cylinder and the master cyl. had a bad seal. After getting the replacement parts from Tony www.LTParts.com I put it all back together. Bleed the system ,then tested it .The replacement hose blew up in my face in the same spot. What went wrong?? Is there a stronger replacement hose? This hose feeds the line to the rear brake caliper. Here are 2 pics , the screwdriver is in the hole where the line blew. This is a 2000 K1200LT if that makes a difference.

I would suggest that it was a weak hose. Your brakes are not servo-assisted and that looks like a natural place for the hose to weaken over time. I would simply replace the hose with a new one. Never been much of one for "used" brake lines. Other parts are OK, but not on brake lines.

Steve,

I have to agree with Jack, no point in using "used" brake hoses. Always replace with new. The early brake systems only monitor the wheel sensors and the ABS unit itself. No brake levels are monitored. That was the same area Steve Rowe had a blow out on his 99 after they put a new MC on. Good rule of thumb is replace all rubber brake hoses at 5 year intervals. Even better is to go to teflon and braided stainless lines.

+1 on the braided lines. Me and Grif did it (Hank did mine, and I guess Grif did his own) and I'll swear, the finger pull and foot pressures felt more 'solid' afterwards - to me at least. YMMV, tho.

Were do you get the braided lines? I am about to replace pads and change the fluid, this would be a good time to replace and upgrade the hoses.

John there may have been but.... it was a wet and muddy ride that day so the bike was covered in dirt when i got home.
Has anyone replaced the entire rear brake line (both flex and the steel tubing) with one stainless steel line? Seams like a better solution with less connection that can fail.

I just found a place here in Austin that makes custom braided brake lines. Just bring your old lines in to match up the fittings.
Priced from $38.00 to $80.00 per line.

I don't know Stevie, maybe it's just me, but I would think sticking a screwdriver in a brake line like that is just asking for trouble later down the road. But hey...what do I know?

Maybe have them make several sets of those brake lines and let your brethren know you got em.

The brake line from the front handle bar to the coupling under the fairing is $85 from BMW alone. So 235 isn't bad for the hole set of rubber I assume.

I agree, especially since there are 6 braided lines in the kit!

You right, if you add the OEM prices up this is almost a bargain . But it's not meant to be a bargain bike anyway.

When one of my front brake lines sprung a leak, I asked these same questions. Everyone recommended the Spiegler lines. The dealer wanted $80 for the one (of six) lines that I needed and the set of six from Spiegler was about $235. A bargin. The local Cycle Gear shop got them in for me at the same price as the Spiegler site. I did the front at that time and just recently changed out my rears. Not a bad job and did seem to give me a better "peddle".

Next I am changing out the scored rear rotor and new pads with EBC from Cycle Brakes.
