This car has popular aftermarket Spiegler brake lines on it, braided stainless lines, these are the brakes and lines: https://www.essexparts.com/ap-racing-by-essex-road-brake-kit-front-9562380mm-porsche-911 Yesterday, on startup with the brake pedal depressed, the front right line burst. See uploaded pictures. The lines have been on the car since April 2021, and the car is regularly service and gets annual or more frequent brake flushes. Inspection at the shop this morning revealed multiple areas of discoloration underneath the plastic sheath that is over the braided line. One of the other lines on the front left was bulging in the area of the discoloration, suggesting that one was close to failure as well. There are no signs of abrasion on the lines themselves, it appears the stainless braided line that encases the teflon inner line is corroding or degrading for some reason. I have contact Essex, the distributor of this kit. The car is at Cantrell Motorsports in Bellevue, Washington and has not been disassembled yet, I would authorize the NHTSA to inspect and take custody of the brake lines if you wish.
