Parking brake system use a what to maintain tension on the parking brake cables and assembly when applied?

Parking brake systems use a spring to maintain tension on the parking brake cables and assembly when applied. The spring allows the brake to remain engaged until the driver releases it, ensuring that the vehicle stays stationary. When the parking brake is engaged, the spring compresses, holding the cables tight and preventing any slippage. Once released, the spring returns to its original position, allowing the brake to disengage.
