Those ‘bubble’ fittings are commonly referred to as double flare fittings. The master cylinder is what the reservoir is sitting on, so these probably go to a proportioning valve or a modulator (I assume you have ABS brakes). While it’s possible to remove these and measure them and buy stock pieces of the same length, you would then need brake line wrenches and a bending tool at the minimum to replace them yourself. An online mega store might have them already formed as direct replacements. Then you would need to bleed your brake system, etc, etc. I would recommend against trying this on your own, though. If there’s one area of a car that MUST work properly, it would be the brakes. Beg, borrow some cash and take it to an independent brake shop.
