Tubing used in hydraulic brake lines must be made from:

Brake lines must carry very high-pressure hydraulic fluid reliably, survive road vibration, and resist heat and corrosion. Steel tubing, especially when wrapped and brazed, provides the strength and leak-tight joints needed for safety. The double-wrapped design adds protection from damage and corrosion, while brazed joints deliver tight, durable connections that won’t seep under pressure and temperature changes. Aluminum alloy would be lighter but isn’t the strongest option for the pressures involved. Copper tubing is relatively soft and can deform or creep under high pressure and heat. Polyvinyl chloride is a plastic that can crack or degrade in brake-fluid exposure and high temperatures, so it isn’t suitable for brake lines. So, double-wrapped, brazed steel tubing best meets the demanding requirements of hydraulic brake lines.
