No you can't ride without without it. I believe it is still available from the dealers & listed at less than $13. at Flatout Motorcycle. Link to comment Share on other sites More sharing options...

skydoc_17 Posted May 25, 2008 Share #4 Posted May 25, 2008 (edited) HI THERE, THERE ARE THREE LINES THAT LEAD FROM THE REAR MASTER CYL. THE FIRST IS THE BRAKE LINE THAT GOES TO THE REAR CALIPER. THE SECOND WHICH IS SHORTER IS THE ONE THAT GOES TO THE FRONT LEFT CALIPER. (THIS IS THE "LINKED" BRAKE SYSTEM) BOTH OF THESE LINES HAVE THE "BANJO" FITTINGS ON EACH END. THE THIRD LINE IS THE LINE THAT GOES FROM THE MASTER CYL. RESERVOIRE TO THE REAR MASTER CYL. THIS IS THE ONLY ONE THAT HAS HOSE CLAMPS ON IT. THE SMOKE YOU SAW WAS THE BRAKE FLUID LEAKING OUT THRU THE RUPTURED LINE DOWN ON THE EXHAUST COLLECTOR. IF YOU HAVE AN OLD FLEXIBLE BRAKE LINE, YOU COULD CUT A SECTION OUT OF IT AND MAKE THE REPAIR. BECAUSE THE BRAKE SYSTEM IS A RELATIVELY HIGH PRESSURE SYSTEM, I DON'T THINK GAS LINE WORK FOR THE LONG HAUL. PERHAPS YOUR LOCAL AUTO PARTS STORE HAS SOME HIGHER PRESSURE LINE. HERE IS A LINK TO SOUTH SEATTLE SPORTS. http://www.yamahasportsplaza.com ONCE YOU GET HERE, SELECT YAMAHA, MOTORCYCLE, 1984, FVZ1200DL OR WHATEVER YOUR BIKE IS, THEN SCROLL DOWN THRU THE DIFFERENT PICS TO THE REAR MASTER CYL. DIAGRAM. THE PART IS ITEM #8, THE PART NUMBER IS 26H-25895-50-00 AND IS $13.59 USD NEW. SOMEONE ELSE MIGHT KNOW OF A BETTER FIX OR HAVE A USED LINE YOU COULD BUY. AT LEAST YOU KNOW WHAT YOU ARE UP AGAINST. EARL Edited May 25, 2008 by skydoc_17 SPELLING...OOPS! Link to comment Share on other sites More sharing options...

It is just a gravity feed from the reservoir to the master. Dick :) Link to comment Share on other sites More sharing options...

Dano Posted May 25, 2008 Share #7 Posted May 25, 2008 Fixed again!!!! Oh, don't forget------ ONLY use DOT3 fluid in there. Now find an all night parts store and get that thing fixed for the ride!!!!! Then replace it as soon as you get the new one in. That's why I ordered new ones for my rebuild project. Dan Link to comment Share on other sites More sharing options...
greg_in_london Posted May 25, 2008 Share #8 Posted May 25, 2008 Oh, don't forget------ ONLY use DOT3 fluid in there Why only use DOT 3 ? DOT4 (or even DOT5/5.1 if it says on the bottle that it will mix - ie not that funny Citroen silicon stuff) should be absolutely fine. Surely the higher numbers will give more protection against brake overheating and fade. The differences are not so great in practice, although I had thought DOT3 had pretty much disappeared. According to Wikipedia http://en.wikipedia.org/wiki/DOT_3 it's use is hanging on in the US though, for some reason. Link to comment Share on other sites More sharing options...
Marcarl Posted May 25, 2008 Share #9 Posted May 25, 2008 The hose you are talking about is a formed hose, so to replace it with a straight piece is asking for trouble. A straight hose in that short of distance is bound to kink and so not let any fluid through, there is no pressure there, so you need free flow. Mine would be parked if I lost it.

greg_in_london Posted May 25, 2008 Share #10 Posted May 25, 2008 It will only kink if it is too long or there is movement, which there isn't. Don't try and over complicate a piece of pipe. A nice thick bit will look right and last for years, but anything that doesn't dissolve will do just fine for now. It certainly won't go brittle in the time that you wait for the postman.

Yammer Dan Posted May 25, 2008 Share #11 Posted May 25, 2008 Find a piece of hose to fit it and ride. I would go to a parts store and find a hose the same size. If need be buy a brake line the same size and cut a piece out of it to fit in there. The bends in it are not enough to make it kink. You could order the formed one latyer if it made you feel better. I wouldn't Link to comment Share on other sites More sharing options...
Dano Posted May 25, 2008 Share #12 Posted May 25, 2008 Recommended DOT3 because the fluid has probably never been changed,,,,,, best to leave a change in fluid type till you can change it all out. Just my opinion (), but definately do not use DOT5! 3,4 or 5.1 are the only ones compatible. Link to comment Share on other sites More sharing options...
gord Posted May 26, 2008 Author Share #13 Posted May 26, 2008 and I tried a piece of straight gas line that I had in my shop from an old Chevy and yep, it kinked, so I parked and will order a new one tomorrow. This is all totally my fault, I put the exhaust back on and for "rust" reasons did not have the heat shields off the back header pipes . I guess I am gonna have to take the exhaust back off and install the shield and might as well go all out and install the new gaskets as well, does anyone know where I can get a set of of exhaust gaskets ? awesome help and awesome site, thanks gord:322: Link to comment Share on other sites More sharing options...
