Hydraulic brake systems rely on brake fluid to function. Leaks can lead to reduced braking efficiency or complete brake failure.

Regular use can cause brake pads to wear down, reducing their ability to generate friction and effectively stop the vehicle.

Over time, brake rotors can become warped or worn, leading to vibrations or reduced braking performance.

Calipers can become stuck or seize, leading to uneven braking or reduced braking force.

Brake lines can corrode over time, particularly in regions with harsh weather conditions, leading to fluid leaks or reduced braking effectiveness.
