Hi All,
I am going to replace all the brake tubes on my '72. Looking on the Rimmer Bros site I see Imperial thread, or metric. Has anyone run into a metric set of brake lines on their car? I didn't know they actually made anything but the Imperial thread. If there's a date range, let me know. Thanks. Patrick
 
I have never seen brake hydraulic parts, for these cars, with metric threads, but I have seen fittings with Imperial threads but metric-sized flats. Perhaps that is what they meant.

In any case, I saw the line sets in the sale brochure from Rimmer, and I was surprised by the cost. The line sets were close to $200. For comparison, a similar set for my Porsche, a few years ago, was under $60. And that is for an early Porsche, where we all are inured to getting reamed on parts prices.

You can get a beautiful flaring tool from Eastwood for $200: > Eastwood Professional Brake Line and Tubing Flaring Tool < .

Then a roll of tubing and some fittings, which shouldn't be more than $50 from Federal Hill (http://www.fedhillusa.com/). For little more than the Rimmer set, you have the tool for future use.
 
After a little digging I see that the caliper is the determining factor only. They can have a metric thread in many of the later ones or aftermarket ones.
If you think Rimmer is nuts, look at Moss! $337 for the same kit!!
 
What I am doing on a tr3 is I purchased a 25ft roll of 3/16 brake line for 28.00$ from a local brake shop and the fittings from Rimmer for like 40.00$ because I need some early stuff that only Rimmer had.

Usually the fittings on British cars is 3/8- 24,UNF, however some of the fittings on the early Triumph stuff is 3/8 20,BSF.

Anyways I would wager a tr6 is 3/8 -24 threads per inch and UHF. I have found you can purchase the 3/8 24UHF at most stores.

I too have found the flaring is difficult to do sometimes/most times. The place I bought the 3/16 tubing will also flare the ends after the line is cut and bent providing you leave an inch of line free to work.

It is not so much the threads, as the flares on the ends of the tubes. You will have to
access a tubing flaring kit that can duplicate the flares needed.Quite a lot of FUN!!
It takes some level of craftsmanship to get it right.But the tubing is cheap and OTC.

DIY is the cheapest and most satisfying option. The brake calipers are the only possible metric threads.
Do not buy a cheap flaring tool as they are a waste of money...There should be a shop close to you that can flare the ends.
 
I am still thinking about the best way to move forward on the brake line flaring. I like Steve’s idea about getting a good flaring tool. Does anyone have any personal experience with the Eastwood flaring tool? I have watched the videos and they make the process look too easy.

Thanks steve
 
I have one, and, yes, it makes the whole process very easy. But for some reason, it makes better flares with ordinary steel brake tubing than with the Cunifer tubing sold by Fed Hill. I had problems flaring the Cunifer tubing with an ordinary flaring tool, too. I think the problem was more with the line than the tool.

Here's my experience with it: > Brakes <
