Making flawless flares is easy if you have the right tools. Here's how we made all our flares on the C10.
45-degree Double Flares
Making 45-degree double or inverted brake flares is slightly more complicated, especially when using stainless steel. I've found that careful preparation, a little antiseize, and resisting the temptation to torque down hard on the flaring tool yields consistent flares every time. We have two tools in the tech center and both do the job well, but the Eastwood tool is by far faster and simpler. The one drawback it has is that when a flare needs to be made near a bend, due to the way it captures the tube, it either needs to be made before the bend is made, or the traditional tool needs to be used. I learned this by mistake!
