The term "steel brakes" refers to a type of braking system that uses steel pads or shoes to slow down or stop a vehicle. These brakes are typically found in older vehicles and consist of two metal plates, one on either side of the wheel rim, which press against the tire when pressure is applied to the brake pedal. The friction between the steel pads and the spinning wheels creates resistance, slowing down or stopping the vehicle. Steel brakes are less effective than modern disc or drum brakes but were once widely used for their simplicity and reliability.
