Hi Guys, As you know, the 2500M borrows much from your TR6 however, many things are slightly different. For instance, the clutch line. Yours uses a hard line/ flex line combination while the TVR runs a red flex line the entire run. The ID is slightly less than 1/8" which translates to 3/16" hard line. Albert at TRF says the TR6 hard line is 1/4" pipe. Are your systems 1/4" for the entire run? My replacement TRW master cylinder is threaded 3/8-24 while the replacement slave is 7/16-20. Anyone have experience with 3/16 vs 1/4 for the clutch line? Any info would be appreciated. Jeff

Jeff, I think on the TR4/A there was an adapter to convert the line at the slave. Don't believe it is available anywhere.
I can only suggest you get a flare tool and put a bubble on the end you need along with the fitting.
When doing the bubble flare be sure follow the instructions Clean out the tube and file the end at a angle all the way around, This will help start the bubble. It takes two times to get it large enough to seal.

If it doesn't have to look original, you might try contacting TSi and see if they can make a custom line with braided SS and the fittings you need.http://www.tsimportedautomotive.com/
ISTR Ted once suggested that (for a different reason) but I found an alternate solution and never followed through. They do make nice brake lines, though (I've got several sets from them).

Thanks for the input guys. Making bubble flares with the correct adapters wouldn't be a problem nor would having a custom line commercially made. My only question is what size line is on the TR6? Does anyone have experience with 3/16" line vs 1/4" line? There is a lot of contradictory info online about the two sizes! Thanks! Jeff

The diameter of the line does not matter.

Personally I would go with Randall's suggestion

When I added a remote vacuum booster to my clutch system I used a combination of 1/4" amd 3/16" lines. I drove the car over 2k miles the last part of this season and it ran perfectly with the combination of pipes and the booster. The booster had ports for 3/16" lines and the master had 1/4". So I simply combined the pipes in the more convenient places. Maybe not the most beautiful work in the world but at least I can still drive the car and hopefully get a few more years of enjoyment from it.

Jeff, checked it at little while ago and 3/16 to the flex line. The flex line had the larger fitting at the slave.
