Brake Flaring Tools

I have that eastwood one and it works awesome. Perfect double flares every time and it only takes a few seconds. The downfall is you have to clamp the tool in a vise to use it so the line has to be off the car. No, you dont need the deburring tool. If your cut is clean it will flare just fine.
There is a similar tool that uses dies that uses a small hydraulic pump you pump with your hand. This can be used on the vehicle. Had I known about this one prior to I would have bought it instead.
Shop around if you go with the eastwood one. Its just a rebranded made in china that can be found cheaper.
