    New OEM/Rubber rear brake line seller?

    I am interested in replacing my old rear brake line (appears original). GS650G(L) 1981.

    I use the rear brake in exactly 2 situations: Emergency stop and Not rolling back on a hill. That's it. I literally *almost ever* use it. I am only paying it attention because the rear caliper was getting sticky.

    In other words, I don't want to spend money on a stainless brake line - but not many places seem to sell OEM type lines. Is there even still an option for a relatively cheap rubber line?

    I was going to suggest visiting the usual online vendors, but I see that hose is no longer available.

    It would not surprise me if the rear hose from another bike would work. It might not have all the padding in exactly the right places, but I'm sure that something would work. What is the length of your current hose? I can compare that to an 850 hose to see how different they might be.

      It makes little sense to buy a rubber line unless you are doing a concourse restoration. A stainless line will be cheaper unless you can find a dirt cheap place local to you to make them.
      And if your brake is sticky the caliper/master should be broken down and cleaned out.

        I saw 3 used Rear lines for your bike on eBay For about $17. Probably no better than what you got. I know from buying a front ss line, swivel fittings and banjos from Venhill you’d be in about $50. Rear is a short line so maybe a little less.

            Fix the caliper & move on. Just my opinion.

              Yeah, I am just going to let it ride. It is really just a parking/hill brake and only good for about 10% of my braking power.

                I'm guessing (hoping) you don't ride in the rain.

                  I've ridden in a lot of rain doing that. If I really want gradual braking fron the rear, I'll downshift.

                  My first year riding, my area got like 20 inches of rain

                    If this is NOT the one you need -- call them and talk through the correct length and fittings -
                    I did my 850GL last year and am very happy --
                    A rear line is $49 I think...

                        You mean..."almost never?"

                        When I took the MSF course, we had to do the "Emergency Stop" (ES) and control the bike at low speed. If you fell off, it was an instant fail.

                        It's good to practice the ES...I would do it before I converted to a single braided front line. My brakes weren't as effective prior to and it made a considerable difference from the rubber brake line.

                          Here is also an option:

                          Your brakes and braking system is one of the most important parts on your motorcycle. These parts are something you want to do inspections on for worn down and damage parts before every ride, to keep you and your bike safe.


                          Clean out the whole system properly. If you split the rear caliper (which you should do, surprising amount of gunk in there usually) there is an O ring you have to replace.
