What the AI looks for in Brake Repair Brake Flaring Tools
- Flare type matches the vehicle
- Most domestic vehicles use a 45-degree double (inverted) flare. Many European and Asian vehicles use a bubble (ISO) flare. Match the fitting. A mismatched flare will not seal and can fail under pressure.
- Die coverage
- The tool needs dies for 3/16 in and any metric size your vehicle uses, plus the matching flare type. A kit without the right die cannot form the right flare.
- Tube material
- Confirm the tool is rated for the tubing you use. Stainless steel needs a robust tool, often hydraulic. Cheap tools crack or form poor flares in hard tubing.
- Repeatability
- Prefer tools with fixed die stops that set tube protrusion automatically. Wrong protrusion is the most common cause of a lopsided or split flare.
Brands that matter
- Mastercool: Hydraulic flaring tool kits.
- Eastwood: Bench and on-vehicle flaring tools.
- Ridgid: General tubing flaring tools; check the brake flare type.
What to avoid
- Cheap bar-clamp kits with poor tube grip and no protrusion stop
- Single-flaring brake lines
- Plumbing flare tools not intended for brake line
Questions
Double flare or bubble flare?
Look at the fitting and the original line: a cone-shaped seat takes a double flare, a rounded bulb is a bubble (ISO) flare. Do not mix them.
