XRAY NT1 Tunable Brake Pulley 21T XN1-47/RE by 3Racing  [XN1-47/RE]

Item Snapshot

This is a scale brake pulley designed for use with Team XRAY NT1 brake assemblies and listed as part number XN1-47/RE. The 21-tooth pulley replaces the stock unit to maintain steady actuation and to allow fine adjustment of pedal feel on race and practice cars.

Fitment tips: follow standard RC disassembly steps to remove the existing pulley, inspect adjacent 走珠軸承 and the brake arm for wear, align the pulley to the cable or linkage, and tighten fasteners to the recommended torque without over-torquing. Intended for model use only.

Setup notes: changing the pulley can change how quickly brakes engage and how consistent they remain. Use it to refine lever geometry, eliminate excess play in linkages, and pair the swap with routine bearing maintenance to preserve braking predictability.
