Hydraulic brake systems can develop leaks in the brake lines, master cylinder, or brake calipers, leading to reduced braking efficiency and potential brake failure.

Overheating of the brake components, especially under heavy usage, can cause a reduction in braking power, known as brake fade.

Air trapped in the hydraulic brake lines or a failing master cylinder can cause the brake pedal to feel spongy or soft, reducing braking responsiveness.

Worn-out brake pads or rotors can cause squeaking, grinding, or other noises during braking, indicating the need for maintenance or replacement.

The Anti-lock Braking System (ABS) sensors or control module can fail, causing the ABS warning light to come on and potentially affecting the system's performance.

Excessive heat and aggressive braking can warp the brake rotors, leading to vibrations or pulsations felt through the brake pedal during braking.

Standard wear and tear can cause brake pads to thin out, reducing their effectiveness and requiring regular inspection and replacement.

Corrosion or debris can cause brake calipers to stick, leading to uneven braking and potential damage to the brake components.
