What function does the connecting spring serve in the braking system?

The connecting spring plays a crucial role in the braking system by holding the brake shoes against the adjuster. When the brake pedal is engaged, the shoes must make firm contact with the drum to create the necessary friction for the vehicle to stop. The connecting spring ensures that the shoes are in the correct position and remain pressed against the adjuster, which helps maintain optimal distance and pressure. This proper positioning aids in effective braking performance and ensures that the shoes can self-adjust as they wear down over time, contributing to the overall efficiency and safety of the braking system.
