Product Description:

The RCW72104 bolt spring is a safety component in heavy-duty applications that prevents loosening of the bolt-pin connection within the brake caliper. It creates a continuous preload force, ensuring the connection remains stable under vibration and impact.

This part prevents play within the caliper mechanism, providing quiet and stable operation during brake caliper repair and reconditioning processes. It particularly protects the reliability of the connection group during brake caliper overhaul and caliper reconditioning operations.

It reduces the risk of knocking and premature wear in applications such as replacing worn or de-elastic springs, caliper reconditioning, and brake caliper reconditioning. In this respect, it is a critical component within caliper repair kits and brake caliper repair kits.
