How to Flare a Stainless Steel Brake Line

Flaring a brake line is necessary when you're connecting the brake line to another segment or to another component. When the line is flared, it won't slide out of its connector and there won't be a leak. A stainless steel brake line is sturdier than the softer copper tubing that's used in household water lines, so you have to use a specific type of tool to flare the line. With a flaring tool kit, the task is simple.

Instructions

1

Find the diameter of the brake line in the holes on a flaring tool clamp.

2

Clamp the appropriate hole on the tool over the brake line, leaving about 1/4 inch of the brake line protruding from the top of the clamp.

3

Twist the wing nuts into the screw holes on the side of the flaring tool clamp to secure the brake line in the tool.

4

Position the flaring tool over the top of the brake line and twist the handle clockwise so the flaring tool pushes into the brake line.

5

Twist the handle until the brake line reaches the flare that you want.

6

Remove the flaring tool and take the brake line out of the clamp. Now it's ready to be installed on the vehicle.
