I need to replace the metal brake lines that run across my firewall because there is no a motor where the lines used to run. I was told by one person that the O.D. of the stock lines is 3/16ths. Is that correct? Also, I'm looking for a good source to buy line ends and a flare tool from. Verocious Motorsports sell the tubing by the foot, but didn't see much else on their site related to brake lines http://stores.channeladvisor.com/ver...8-4-ML-BA-C20?

 

Any local NAPA should have all the fittings and be able to make the lines for you.

 

I believe the stock line is a metric line (probably a 5mm) but the 3/16ths fittings seem to do fine.

our local parts store has a big box of brake tubing in stock. they are just a small chain store too

 

3/16 line is fine. Metric fittings, 10mmx1.0

 

does it matter if FD, or other gen? are they all the same (3/16 or 10mmx1.0 as stated above)?

 

is this the right tool to use?

for the oem fittings you will need the double flaring tool from the link. personally I like to convert everything to AN, only need a single 37* flare. It makes things alot simpler down the road. Be sure to make the double flares without cracking the tubing, practice on some scrap before working on the good line. Stock line can be a bit brittle also so be careful making the flares.

 

I've NEVER had good luck with flaring tools.. They're a pain in the ***. I ended up using pre formed line, had some custom made at a shop in LA (sorry, forget the name). I sent them the length, tube size and end thread pitch, and bent it to fit.

the double flare is a bit trickey. One tip that has helped me through the years is to use a file or a belt sander to clean the cut end of the tubing before flaring. also use a good quality tube cutter and practice makes for better results. this is another reason to use the AN sittings as you will only need a single flare.
