Can Converting Rear Drum Brakes to Disc Brakes Pass Annual Inspection?

[Elias]

Converting the rear drum brakes of a car to disc brakes can pass the annual inspection as long as it is registered with the vehicle management office and does not affect the braking performance. Generally, as long as the braking system functions properly during the inspection, the vehicle will pass. Annual inspections typically do not pose issues unless modifications involve changing the car's paint color, applying full-body decals, altering the body structure, or damaging the license plate. Definition of Front Disc and Rear Drum Brakes: Disc brakes, also known as hydraulic brakes or oil brakes, are a modern braking system. Drum brakes, on the other hand, are a traditional braking method where brake pads create friction against the drum to slow down the vehicle. Most vehicles on the market use disc brakes for the front wheels and drum brakes for the rear wheels, commonly referred to as the front disc and rear drum configuration. Differences Between Drum Brakes and Disc Brakes: The primary difference between drum brakes and disc brakes (also known as rotor brakes) lies in heat dissipation. During high-speed driving, drum brakes struggle with heat dissipation, leading to heat accumulation and potential thermal fade, which reduces braking efficiency. In contrast, disc brakes offer better ventilation and faster heat dissipation, making them less prone to thermal fade.
