When you make new brake lines, the bends need to be smooth. A kink restricts fluid flow and weakens the tube. A tubing bender supports the tube all the way around the bend so it keeps its round shape.

Quick verdict

  • Best for: DIYers making brake, fuel or transmission lines.
  • Type: handheld three-head bender (Eastwood part 12435).
  • Strengths: four tube sizes, bends up to 180°, light and easy to use.
  • Watch out for: hard stainless tube takes more effort than steel or copper-nickel.

Key features

  • Bends 3/16, 1/4, 5/16 and 3/8 in tubing.
  • Works on steel, aluminum and copper tubing.
  • Smooth, tight bends up to 180° with angle markings.
  • Die-cast aluminum body, about 11 in long, with cushioned grips.
  • One-year Eastwood warranty.

Tips for neat brake lines

  1. Use the old line as a template where possible.
  2. Slide on the tube nuts before flaring.
  3. Make bends in order from one end, checking fit as you go.
  4. Leave straight sections near each end for the flaring tool.
  5. Bleed the brakes fully after fitting and check for leaks.

Pros and cons

Pros

  • No kinks
  • One tool for four sizes
  • Small enough to use under a car

Cons

  • Very tight bends near fittings may need forming pliers
  • You still need a flaring tool

Safety note: brakes are safety parts. If you are not sure how to do the job, have a qualified mechanic do it.
