Product Summary

This scale RC brake pulley is made for Team XRAY NT1 brake assemblies and is supplied as part number XN1-47/RE. The 21-tooth pulley is a direct replacement designed to deliver consistent brake actuation and let you dial in pedal feel on competition and club-level model cars.

Installation notes: remove the old pulley following normal RC teardown steps, check the related 走珠軸承 and brake arm for wear before fitting, align the pulley with the braking cable or linkage, and torque fasteners to the correct level without over-tightening. This item is an accessory for scale models only.

Tuning advice: swapping the pulley alters engagement characteristics and repeatability. Check lever geometry, reduce linkage free play, and combine replacement with bearing cleaning and lubrication to maintain predictable braking behaviour.

Will this pulley fit any XRAY NT1 build?

It is specified for the NT1 brake assembly; confirm the shape and mounting hole pattern on your car before installing to ensure proper fit.

What checks should I do during installation?

Inspect the 走珠軸承 and brake arm for damage, verify pulley alignment with the cable or linkage, and set fastener preload to avoid slop while preventing thread damage.

Can changing the pulley improve consistency on repeated stops?

Yes. A fresh, correctly installed pulley helps keep lever motion smooth and makes braking response more repeatable, especially when paired with clean bearings and correctly set linkage.
