Brake Spring
What it is: A brake spring is a component in braking systems, typically used to return brake components (e.g., brake shoes, levers, or pedals) to their resting position after being engaged. This could refer to parking brake lever return springs, rear brake return springs, or springs in drum brake systems.
Function: Ensures brakes disengage properly when the pedal or lever is released, preventing drag and maintaining system responsiveness. For example, parking brake lever return springs are sold for various vehicles, including Chevrolet and GMC models from the 1970s to 2000s.
Relevant Information: Web results highlight parking brake lever return springs available on Amazon for models like Chevrolet K20 or GMC K1500, and specialized tools like brake spring locking pliers for compressing these springs during servicing. Additionally, spring-applied brakes (e.g., for servo motors or parking brakes) use springs to hold brakes in place when power is off, as seen in fail-safe brake systems.
Possible Application: Common in automotive drum brakes, parking brake systems, or industrial applications like spring-applied power-off brakes for motors.
