Spring Stop
SAF-Holland

Within spring brake or EPB (emergency/parking brake) systems, the stopping element provides a controlled termination point for spring movement, preventing overtravel and preserving the correct geometry of the actuation sequence. This component is essential for maintaining reliable release and retraction of the spring brake, especially under high-load conditions where thermal expansion and vibration might otherwise cause misalignment. The VMRS code 059-001-082 places it in the component family of braking actuators, while the category 42813 clarifies its role in spring brake assemblies. By offering a defined travel stop, it helps protect other moving parts from improper contact, reduces the risk of binding, and promotes consistent braking response during cycles. The part is designed for compatibility with common spring brake architectures used in heavy-duty trucks and trailers, and its durability supports extended service intervals in fleets operating at high duty cycles with frequent cycles of parking and release. In maintenance routines, inspecting the stop for wear, cracks, or deformation is a straightforward way to prevent cascading failures, improve safety margins, and sustain predictable performance across temperature ranges and road conditions.
