If the YIKONG YK4107 RC Car Parts Brake Camshaft Set (21089) feels stiff or doesn’t move smoothly, it is often caused by dirt, sand, dried grease, or a lack of lubrication around the camshaft and pivot points. In some cases, loose or damaged components may also affect brake movement.
To restore smooth operation, clean the Brake Camshaft Set thoroughly, inspect all moving parts for wear or damage, and apply a small amount of RC-grade lubricant to the pivot points if needed. Avoid using excessive grease, as it can attract dirt and reduce braking performance. Regular inspection and cleaning will help keep your YIKONG YK4107 RC Car braking system operating smoothly and reliably.
