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

Brake stopper pulley for Kyosho V One RRR and SIII

This replacement pulley is designed for use with Kyosho V One RRR and V One SIII RC chassis as a brake stopper component for scale-model braking linkages. The 21T tooth count defines engagement geometry and helps set consistent brake action during tuning and routine service.

Fitting uses the same mounting points as the original pulley and requires only common hobby hand tools. The pulley functions as a tuning element rather than a main load-bearing part, allowing precise adjustment of engagement point, return position, and linkage free-play when you swap or service brake components.

On replacement, inspect adjacent linkage and any 走珠軸承 for wear, check alignment, and confirm the brake returns smoothly through its full travel before full-power runs. This item is supplied as an RC-scale accessory compatible with Kyosho V One RRR and V One SIII and is intended for model use only.
