You could experience loss of braking if __________.

Loss of braking can occur when there are leaks in the hydraulic lines or hoses. The braking system relies on hydraulic pressure to function effectively; if there are leaks in the system, this pressure can diminish, potentially leading to a complete loss of braking ability. The hydraulic lines carry brake fluid from the master cylinder to the brake calipers, and any compromise in these lines, such as a leak, directly impacts the pressure needed for reliable braking.

While other factors like old brake pads, low brake fluid, or warped rotors could affect braking performance, they do not have the same immediate and severe impact on the hydraulic system as leaks do. Old brake pads might lead to reduced friction, low brake fluid can result in diminished braking response, and warped rotors can cause vibration and uneven braking, but none of these issues can cause a total failure in the brake system quite as directly as a hydraulic leak can.
