    master cylinder geometry and position.

    OK , my new to me 82 gs750T has those mild ape hanger style handle bars and that puts the master cylinder at a bad angle , atleast to me, as the fluid enters neard the inside or what becomes the upper section and what could possibly be the part of the reservoir that runs out of fluid first and could grab a fist full of air .

    Am I worried about nothing ? Can I use one of those masters from a bike that has a 45 degree angle ? How important is it to have the brake line hooked to the side vs the end ? Does it matter as long as it reachs ?

    BTW my current setup is very soft to me, I can bring the grip to the bar with one hand. (have replaced and bleed the fluid so the master
    needs work or replaced anyway)

    anyone ?

      I would change the bars first, might be easier and cheaper than a new master cylinder. Go to a junkyard and sample a few bars to see what might work

      1980 GS1000G Power corrupts, and absolute power corrupts absolutely

        Like you said, there's a good possibility that the master cylinder is leaking internally if you can pull the lever to the bar... but consider as well that the old original equipment rubber hoses down to the caliper don't age gracefully either. They reach a point that they don't hold pressure very well and will actually swell when you apply pressure. Consider new hoses, or even aftermarket stainless braided hoses as a cure for the pressure drop blues.

          Is there any sources for the stainless lines for single caliper front
          brakes ? Or know of another modern bike with the same lenght lines?

            There's quite a few suppliers for these type hoses. I've seen many of them mentioned in posts here of late. Do a search on brakes, hoses, and stainless braid. You'll find several I'm sure.

            These are some I located simply by googling the Web...

              Problem is none of these help me. I have NO experience with brake lines and these sights either list bikes that do not include mine or require you know what size you need . I know it's 43" long but what modern bike might have that size ?

                You may actually have to browse the sites (I'd ignore the U.K. sites to start with) and locate an 800 # or something and give them a call, personally I always look for a contact e-mail address and send them a query along the lines of what I need. These folks are usually pretty willing to work with you in the effort to make a sale. Tell them what year/make/model you have and see if they have some application charts other than what's on their site. Obviously they'll figure to make more sales to later model bikes so that's where they'll concentrate their published data.

                I personally don't know of any specific bikes that have the same length and size hoses that yours may have. That'd take someone with a huge amount of hands-on experience with a very wide range of brands, makes and models. I suspect you'll have better luck trying to aftermarket shops and begging their assistance to help you out.

                I know as well that's there's folks here on this site that have purchased braided lines from various sources and can help you determine who to deal with. Give them a few days to see these posts and the advice will drift in.

                  We do not carry parts for this bike.

                  And here is the typical response I have gotten from the link posted.

                    Re: We do not carry parts for this bike.

                    Stainless Steel Braided PTFE Hose, Custom Brake Lines, Washing Machine Hose, stainless steel braided PTFE, heat pump hoses, power trim hoses, silicone vacuum tube and Audi Performance


                    If Paragon does not make a kit that will fit your bike, then you can get 50% off of your order. They have links that show you what fittings are which.





                    And go ahead and buy a rebuild kit for your master cylinder.



                    Click on application chart link to find which one you need.

                    And if you don't have a manual, you need one....

                      Ok this is looking better. Can anyone tell me the inner diameter I have or should get ? Like I said mine states 1/8 on the brake line but NO ONE
                      makes one that small so either I need to upgrade or my hose is marked wrong.

                      And what do you crimp on the bango with barb fitting with ?

                      BTW I do have the factory service manual.

                        Does your master cylinder look like the one in the picture in your manual?

                        If so, then I'll bet you $10 you can fix your problem with the links I gave you.

                          well let's see, the link for the ms rebuild kit does NOT have the 82 GS750T model listed, I win.

                          And my manual for what ever reason has no specifics on the "T" , it
                          must have been a late add on or such.

                            I can't help you then, you have no clue. Sorry to be a jerk, but you are not listening. Other than browsing the sites, you never even tried. With these bikes, not everything will be off the shelf or an easy fix, get used to it. The parts are available, but you have to work for it.

                            Paragon makes custom lines, or if they don't have the kit you need for your bike, they will make one for 50% off. Tell them what you have and they can figure it out.

                            Cycle Recycle II has the parts you need, but you may have to call them. If they don't have it, or are not willing to help you, then send me your address and I'll send you 10 crisp $1 bills Most people on this forum will back me up on the fact that they have it and that I am good for the money if they don't. BTW -(Don't let the low post count fool ya, I've been in the saddle a while and know where to get parts.... )

                            And last but not least, The Clymer manual link I gave you covers the "T".

                            www.bikebandit.com has most of the master cylinder parts you may need too. I'll let you look that up.

                            Now I'm done with you...... Good luck!

                              Brake lines can be fabricated. That is not an issue. Measure what lengths you need and contact that company. The banjo fitting are universal. Just tell them if you need angles or straight fittings. I am not big on ape hanger bars. I personally think they are dangerous but then I am old. But hey I thought they were stupid when Peter Fonda had them on the Capt. America bike and I was a teenager then.
