féktárcsát

Féktárcsa, commonly translated as brake disc, is a crucial component of a vehicle's braking system. It is a rotating disc that is attached to the wheel hub. When the driver applies the brakes, brake pads are pressed against the surface of the féktárcsa, creating friction. This friction converts the kinetic energy of the moving vehicle into heat, slowing down and eventually stopping the vehicle.

Féktárcsák are typically made of cast iron, but high-performance vehicles may use materials like carbon-ceramic for improved heat dissipation and reduced weight. They come in various designs, including solid discs and ventilated discs. Ventilated discs have internal vanes that allow air to circulate through them, helping to cool the disc and prevent overheating, which can lead to brake fade.

The condition of the féktárcsa is vital for safe braking. Over time, they can wear down or become warped due to repeated heating and cooling cycles. Signs of a worn or damaged féktárcsa include squealing or grinding noises during braking, vibrations in the steering wheel or brake pedal, and a noticeable increase in braking distance. Regular inspection and replacement of worn féktárcsák are essential maintenance tasks for any vehicle.
