Flare Type and Tool

I have a Wilwood 4 disk brake system and I'm ready to connect the lines. I need to purchase a flaring tool. I wanted to know what type of flare (45 deg. single or double??) is used and a reasonably priced tool to purchase. I purchased pre-bent stainless steel lines and will need to modify them to fit.

Also, should I cut the lines that run along the rear axle short of the rear caliper and install a rubber/steel braided line or plumb it directly to the caliper? The caliper is fixed. Thx!

Re: Flare Type and Tool

Brandon,

SS is very hard to double flare. The line is 3/16" and a regular double flare tool will not work. Plus the tool that does it is like 400.00. There is a guy in Katy that makes lines and has the correct tool. Only problem is you cant flare a close 90 due to the adapter that holds the tubing is about 1" so a 90 will be about 2 to 2-1/2" long.

I will try a find the name of the shop. I made prebent lines out of galvanized tubing them he measured them and made them out of SS for my master cylinder.

I would get some brake braided line to attach to the caliper, then mount a bracket on the frame for the top of the hose. Wilwood sells them. Then run the hard line to the braided hose. That way if you have to take the caliper off you will have a fexible line.

Re: Flare Type and Tool

Ridgid 345 DL is as nice a hand held flaring tool as I've used, but I've never tried it on SS tubing. The problem with SS is that it's expensive, and if you bungle a flare (we all do!) your tube is shot. I understand that SS tubing is pretty and all, but really, how often will you crawl under your car and admire your brake lines? I'd just buy some regular steel tubing which is dirt cheap, bend it, flare it, and if the urge strikes polish it with some 0000 steel wool and clear it.

Beautiful car. I've always been a fan of Butternut Yellow.

Wink Re: Flare Type and Tool

If - you do decide to go SS ...
Make sure you buy #321 Seamless tubing for your lines
SS-321 is annealed and will bend and flare without cracking.
If you can't find it locally, it is what most of the 'Stainless' line companies sell as their line.
Aircraft supply stores also carry it, check with you local airport parts guy.

I use a "Blue-Point" tool usually - works just fine

Re: Flare Type and Tool

It's a 45 degree double flare. You can do it if you're patient, measure multiple times for your cuts, and practice first. I found a cheap tool that had the 3/16" hole in the tubing clamp at the very end so it would be close to the clamping point. Then I also locked the clamp in my vice. Put a drop of oil on the die when you are flaring it. Also, cut the tubing with a Dremel or fine tooth hacksaw blade because a tubing cutter will work harden the tube so it won't want to flare. Be sure and clean everything well after you're done.

The best thing if you want to tackle it would be for your first try, only cut off a small piece of the tubing. Like say if you needed twelve inches removed, just cut off a six inch piece. Then cut that piece into a few pieces so that you can practice flares on them. If after trying a few you don't think it's going to work, you can just mark your tubes where they need to be cut and take them to a hydraulic hose shop which will do them for you pretty cheaply. Remember to leave about a 1/4" extra length for the flare. Also, DON'T FORGET TO PUT THE NUT ON BEFORE YOU FLARE IT! Ha ha....you sure wouldn't be the first.

As for the question about the rear line, I would install stainless flex lines. If you ever need to remove the caliper for any reason it makes it much easier.

Re: Flare Type and Tool

Thanks for all the suggestions. Unfortunately, I have already purchased the ss prebent lines from Classic and installed them. They are over a year old so they will not accept a return. Hopefully, they are ss-321. I will look into that. The only modifications I need to make are at the axle lines to the rear calipers and I need to install the proportioning valve on the rear line. Everything else looks like it may line up pretty well.

I was thinking the same thing about braided lines to the caliper so I will go that route.

Also, BPOS thanks for the compliment on the car!
