Kyosho V One RRR/V One SIII Brake Stopper Pulley 21T by 3Racing V3R-018  [V3R-018]

Brake stopper pulley for Kyosho V One

This 3Racing replacement pulley is designed for use with Kyosho V One RRR and V One SIII RC chassis as a brake stopper component, intended for scale-model braking assemblies. The 21T configuration identifies the tooth count that determines engagement geometry within the brake linkage, making it a direct service part for brake tuning and routine maintenance.

Installation is straightforward on chassis that accept the original style brake stopper pulley, requiring the same mounting points and basic hand tools. The pulley serves as a tuning element rather than a primary load-bearing part, allowing fine adjustments to brake engagement, return position, and linkage free-play when swapping or upgrading brake components.

When replacing the pulley, inspect the surrounding linkage and any走珠軸承 for wear, confirm alignment, and verify that the brake returns smoothly through its full travel before running full-power tests. This part is described and marketed specifically as an RC-scale accessory for Kyosho V One RRR and V One SIII models and is intended only for model use.
