RV 14A Brake Line Leaking

I have about 215 hours on my 14A and have had to replace the right brake line twice and the left line once. Each time the leak has been from the brake line flare at the top of the landing gear strut. Has anyone with a 14 had this problem? Thanks. Jim

Three failures suggests a systematic problem.
Are you using the correct (aviation, not auto) flare tool? They are not the same.
All the correct parts, including the correct size sleve?

Also are you using the Beringer brakes, stock kit brakes, and what fluid?
