What is bubble flare brake line?

Bubble flare brake line is a type of brake line used on aircraft. It is generally made of metal or plastic and has a large radius at the point where it joins the drum or disc brakes. This allows for more consistent braking performance, even when the airplane is flying through rough air.

How to identify bubble flare brake line?

Bubble flare brake lines are usually identified by a series of small bubbles near the connection to the caliper. The bubbles form when the brake fluid is forced out of the line, and can be indicative of a problem with the line. To check for bubble flare, remove the wheel and flex the caliper arm where the brake line connects to it. If there are any bubbles present, they will likely be visible in this area. If there are no bubbles, but the line feels stiff or rubbery, there may be a problem with the line elsewhere and it should be replaced.
