What type of brakes are gradually being replaced by four-wheel disc brakes?

Four-wheel disc brakes are gradually replacing drum brakes because of several advantages that disc brakes offer. Disc brakes typically provide better stopping power and improved performance under high-stress conditions, such as when vehicles are heavily loaded or during aggressive driving.

One of the key reasons for this transition is that disc brakes are less prone to brake fade, which happens when brakes lose effectiveness due to heat buildup. Disc brakes have a better ability to dissipate heat because they are exposed to airflow, helping maintain their performance even during continuous use.

Additionally, the maintenance of disc brakes is often easier than that of drum brakes. Drum brakes can be more complex to service because they sometimes require the disassembly of parts that may not need attention regularly. In contrast, disc brakes provide easier access to the brake pads and rotors, typically simplifying maintenance tasks.

As automotive technology advances, manufacturers are leaning towards designs that enhance safety and performance, making the transition from drum brakes to four-wheel disc brakes a natural progression in vehicle development.
