i have a bn6 with a sbc conversion that i am redoing the brake system ti include new brake lines. since i am rerouting the lines and installing a wilwood dual circuit master cylinder the stock bake lines will not be used. can anyone tell me what the proper thread and flare type for the rear wheel cylinders might be. the car is a 59 100-6 bn6....two seater. thanks for any help! i will be using 3/16s cunifer brake lines that i will bend and flare myself! thanks for your help.

All flares on the Healey except the booster are 3/8-24 double flares. The booster, if I recall correctly, uses bubble flares. If you're using the Jag rear discs, they'll require bubble flares at the calipers.

Flare nut on left is British style, with extension. American flares - threaded to end as per nut on right - likely the Wilwood will use this style. Nuts are not interchangeable, so save your old ones.

Flaring tools: Harbor Freight tool is worth buying for the button dies alone. Tool itself is likely to be worthless. Mine makes a crooked flare. Ridgid 345 flaring tool available on Amazon for around $50 can use these dies to make good flares. There are YouTube videos on flaring. Do not tighten the tool down all the way as it is good for the flares to have a little give left in them when you install them. Same setup can make bubble flares if necessary.

I built a dual-circuit system for my 4-wheel discs using a Fiat 124/131 dual MC - pictures and suppliers:

Federal Hill is the most educational site for anyone interested in building their own brake lines:
