NISSAN 36191-C6000 Drum Brake Adjusting Screw Spring

The genuine Nissan 36191-C6000 drum brake return and adjusting spring (SPR-ADJ SCREW) is an essential component of the drum brake system's self-adjusting mechanism. Its function is to provide continuous tension to the brake shoe adjuster assembly, ensuring optimal clearance between the brake shoes and the brake drum throughout brake lining wear.

Technical Features and Functions:

• Material Quality: Premium high-tensile, heat-treated spring steel engineered to withstand the high temperatures and mechanical stresses generated within the braking system.
• Corrosion Protection: Specially treated surface providing reliable protection against the corrosive effects of moisture, road salt, and brake dust.
• Precise Tension: Calibrated spring tension for exact retention of the brake adjusting screw (star wheel), preventing unintentional rotation or loosening.

Signs of Failure or Wear:

Over time, brake springs can lose their elasticity, stretch, or break due to sustained thermal cycles and mechanical fatigue. Typical symptoms of failure include:

• Brake pedal travels unusually deep or feels spongy.
• Uneven brake shoe wear due to improper clearance adjustment.
• Brake noise (clicking, metallic, or squeaking sounds coming from the drum brake).
• Failure of the self-adjusting mechanism, leading to diminished braking performance.

To ensure safe and balanced braking performance, replacing the return and adjusting springs is strongly recommended whenever servicing the brake system or installing new brake shoes.
