Are Brake Lines Double Flared

All brake lines need to be double flared, due to the high hydraulic pressure. If your brakes leak or the hoses crack, it could prove to be fatal. Single flared lines are suitable for low-pressure lines in other applications, but not your vehicle’s brakes.

Is it OK to single flare brake line?

1. Single Flares are only acceptable on low-pressure lines, but not acceptable for high-pressure brake systems. A single flare is just as it sounds, the line is flared out just once in a conical shape. Single flares are not acceptable for brake lines and tend to crack and leak quite easily.
