About Stoptech

StopTech, a Brembo company, engineers big brake kits and high-performance rotors for street and track-day cars. AeroRotor cross-drilled discs and ST-series calipers deliver fade-free repeatable braking — the choice of Optima Search and SCCA road-course competitors.

Maintain Peak Brake System Performance

The Stoptech Anti Knock-Back Spring is a small but vital component designed to ensure the consistent and reliable operation of your braking system. Engineered to provide 4lbs of force, this spring helps to prevent brake pad knock-back, a phenomenon where the piston retracts too far into the caliper after releasing the brake pedal. This can lead to a longer pedal travel on the next application and potentially reduced braking responsiveness.

Essential Brake Hardware Features:

  • Prevents Pad Knock-Back: Actively works to keep brake pads closer to the rotor surface, ensuring a firmer and more immediate pedal feel.
  • Optimized Piston Fitment: Specifically designed for pistons ranging from 26mm to 36mm in diameter, offering broad compatibility with various caliper types.
  • Consistent Force: Delivers a reliable 4lbs of force to maintain proper piston positioning.
  • High-Quality Construction: Manufactured by Stoptech, a leader in high-performance braking components, ensuring durability and effectiveness.
  • Sold Individually: Allows you to purchase only the quantity needed for your specific brake caliper or system requirements.

Properly functioning anti knock-back springs are crucial for maintaining the crisp pedal feel and responsive braking performance expected from a performance-oriented vehicle. Whether you are performing routine maintenance or upgrading your brake system, these springs are an essential part to consider. Ensure your brakes are always ready when you need them with this quality component from Stoptech, available at GGCRACING.
