Wedge TR7 brake hard and flex lines - fittings

[TR Craving]

Hi all,

I will be replacing all the hard and flex lines on my TR7. Before I start bending and flaring the hard lines and ordering the stainless braided flex lines, can anyone confirm that all the fittings on the car are ISO bubble flares? Are there any fittings that are 45 degree double flares?

Thanks
TR

I have never own a tr7, but most big cities have hydraulic repair shops that specialize in fabricating hydraulic fittings and lines by duplicating the original. The times I have had a weird challenging flare that I could not duplicate, I take it to them. Often the one is end made up from their supplier and the length and the other end needs to be made to fit. tr7 is probably a common thread i remember i had to convince them tr3 was standard thread. they have those rubber heating and criping tools and braided lines

Thank you for your response and insight, Steve. They should be common thread. I'll have to confirm that. I'll see if there are any hydraulic shops in the area.
Thanks

TR,
This inexpensive Eastwood tool makes what Moss calls "universal" flares which will work in either bubble or double applications.

Hi buddy,
There are two basic types of flares used on OEM automotive brake systems throughout the world. The SAE/double (inverted/45degree) flare and the DIN/ISO bubble flare. We will refer to them as SAE or DIN flare. The most common is the SAE flare. Typically found on all American and Asian cars, but the European style DIN flare is appearing everywhere now.

Never use a single flare on automotive components. The SAE/double flare standard is remarkably tolerant of production variations, but the assemblies must be the same standard. Single flares are never allowed on steel brake lines.

+1 on the flaring tool shown above. I used that tool to make all the double flares on my TR3 when I remade my brake lines. Works beautifully on Copper Nickle 3/16 lines.

Dunno about the TR7, but the TR4/4A uses a mix of 45-degree double flares and Girling bubble flares. So I'd prepare for the same kind of thing on any other TR.

Thank you everyone for taking the time to help me with this. Steve, that tool is exactly what I need and a lot more afforadble than other similar but single-type flaring tools. Mastaphixa, thanks for that.

Akbaradeli and Sarastro, that gives me a good idea what the flare will need to be.

Cheers everyone!

Hi Steve, I just went to the Eastwood.com site and searched the 31244 number and got a different price unit? Is this the same website that you refer to? Or did I search the wrong item?

Welcome to inflation. The '70s live!

Ha Ha yes you are so right! Inflation really is skyrocketing these days, and it's not just gas prices and tools! Hold on to your wallet... if you can. Maybe this is just the beginning?

All repairs to a 7/8 start at the wedge shop. Replace the front brakes with the Wilwood conversion
This will likely save your life. Comes with the steel flex lines (front) add the one in the rear and the Tr7
is now down to it's dodgy rear brakes. Good luck with them. GOK who can fix these suckers.
We replaced these with disc brakes on the race car .A hybrid of the front tr7 calipers you just removed
and a Mazda rear brake rotor. You lose the E brake completely, but can now brake with a Porsche.

Thanks MD, great advice. The price of the WS Wildwood brake kit means it can't be done for now, though. It won't be going on the race track so a more econo option is needed for now.

Your suggestion of the old front calipers on the rear with Mazda rotors is an excellent idea! Thanks!
