Why don't disc brake systems usually require adjustment?

  1. They are made of solid materials

  2. They use self-adjusting mechanisms

  3. A certain amount of pressure is maintained by the metering valve

  4. They always wear evenly

The correct answer is: A certain amount of pressure is maintained by the metering valve

The reason that disc brake systems usually don't require adjustment lies in their design and functionality. They operate with a relative simplicity that eliminates the need for frequent manual adjustments. In disc brake systems, the design allows for a consistent engagement of the brake pads on the rotor. As the brake pads wear down, the hydraulic system compensates for this wear efficiently. The metering valve plays a crucial role in maintaining a certain amount of pressure within the system, ensuring that the brake pads remain in close proximity to the rotor, providing effective braking performance without the need for manual adjustments. While self-adjusting mechanisms can be found in some braking systems, it is the hydraulic pressure management that predominantly maintains the efficacy of disc brakes, contributing to their reliability and low-maintenance nature relative to other brake systems. This characteristic is why disc brakes are favored in many modern vehicles for their ease of use and reduced maintenance requirements.
