Kerékfékek, commonly translated as wheel brakes, are a vital component of any wheeled vehicle, responsible for slowing down or stopping its motion. They function by converting the kinetic energy of the moving vehicle into heat through friction. The primary mechanism involves applying a braking force to the rotating wheel.

There are two main types of wheel brakes: rim brakes and hub brakes. Rim brakes, often found on bicycles, press brake pads against the rim of the wheel. This is a relatively simple system but can be affected by dirt or moisture on the rim. Hub brakes, on the other hand, are integrated into the wheel hub. Disc brakes and drum brakes are common examples of hub brakes. Disc brakes utilize a rotor attached to the hub and calipers that squeeze brake pads against the rotor. Drum brakes enclose the braking mechanism within a drum attached to the wheel, with brake shoes expanding outward to create friction.

The operation of wheel brakes is typically controlled by a lever or pedal, which the operator manipulates. This action initiates a mechanical, hydraulic, or pneumatic linkage that transfers the force to the braking components. The effectiveness of wheel brakes is crucial for vehicle safety, allowing drivers to control speed and avoid collisions. Regular maintenance, including checking brake pad wear and fluid levels, is essential to ensure optimal performance.
