This 20T brake pulley is a direct replacement for XRAY NT1 brake assemblies, supplied as 3Racing part XN1-46/RE. It is designed to mount on the NT1 brake shaft and mate with the surrounding brake linkage on 1/10 touring car chassis.
Fit this pulley when renewing worn brake drive parts or when restoring the original gear ratio after linkage changes. The 20T tooth count is the key engagement attribute; confirm the existing pulley is 20T before fitting.
Installation notes: remove the brake assembly from the chassis, slide the pulley onto the brake shaft, and check centring and clearance with nearby components. After installation, rotate the brake system through its full travel to confirm smooth engagement and correct tooth mesh.
Tuning role: the pulley tooth count affects how the brake drive interfaces with the brake train, so replacing like-for-like preserves the NT1 braking feel and leverage.
