I'm posting so much lately that I'm starting to feel needy.
My front hoses area getting soft and I want to replace the hoses. I could buy hoses of ebay or source the parts from a Triumph vendor. I was thinking of going ss braided line from the master cylinder to the calipher and get rid of all the extra fittings in between. Just more chances to spring a leak. Is there someone local that can make a line that with either the old fittings at the calipher and master cylinder or that would have new fittings?
As an option is it possible to replace the original hoses using the old fittings with new ferrels?
If the fittings should be replaced where can the fittings be sourced. Are the fittings the British thread size or will metric or SAE size fittings work?

Updating this post for those that may need the info in the future. I was under the impression that Triumph used BSP (British Standard Piping) sizes on their brake line/hose fittings. I spoke with Bob at Expert Motorcycles in Hobart Indiana. He said that in the 1970’s Triumph incorporated more UNF sized fittings, bolts etc. on their bikes and got away from Whitworth and BSP sizes. He said my lower brake hose fittings should be UNF sizes 3/8” x 24 threads. A local shop in INDY was recommended that would put a new line with fittings together for the bike. I called Earl’s INDY today and they said they can make a steel braded replacement hose to replace the old one for less than ordering one online. I will post here how it turns out. Here is their website: www.earlsindy.com |

For everyone out there, 1970 was the last year for Whitworth / BSP threads on Triumph's ( I do not know about other British brands) If you have an engine or frame that is pre 71 special fasteners and tools are needed to keep from messing up the parts. SAE threads, in some sizes (diameter and threads per inch TPI) are VERY close to the Whitworth size but the thread profile is completely different. This means many a pre 70 Triumph sold in the US has jacked up bolt holes and mismatched hardware. Something to think about/look out for when looking at the older Trumps...

P.S. Zilch I didn't realize that's what your concern was. Since I have all cable brakes I didn't reply sooner. Sorry about that. Nova.

Life is much easier with the 76 Tri compared to the 68 BSA I had. I was confused or had a flashback about fastener sizes, all is better now, thanks Nova.

Lots of quirks to remember about old Brit bikes. :-)

Got the new stainless steel braided hose made at Earl's INDY last Friday. I gave them the old lower hose from the T140 front brake. It had two 3/8" x24 UNF extended male (bulkhead) fittings. They mtached up the hose and fittings. The hose was finished in 5 minutes. Even with new fitting nuts it came to $20. A new replacement hose and shipping would be $45. When I installed it the upper hard line had a bad flare that was leaking. I replaced it with a 3/16" coated brake line from O'Reilly's. This line was so bendable I was able to bend it by hand. I used the old nuts and borrowed a double flare tool from them and used the old fittings. I am going to replace my top master cylinder hose with stainless steel braided hose. They can make it and have the banjo fittings for about the same price.
Now my issue is my front calipher is holding onto the brake disc even with the pressure off the system. I know the calipher is adjusted correctly and releasing hydraulic pressure when I let go of the brake lever. The bike sat for so long it is probably corrosion or gunk that needs to be cleaned out.
