Buying advice

When choosing a brake flaring tool, consider the types of flares you need (SAE double or ISO bubble), the tube sizes you'll work with (commonly 3/16" and 1/4" for brakes), and frequency of use. For occasional DIY, a budget kit with multiple dies offers value; for frequent professional use, invest in a heavy-duty set with replaceable dies and a strong clamp mechanism. Always verify the tool is designed for steel tubing if working on automotive brake lines.
