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

Part Overview

This scale brake pulley fits Team XRAY NT1 brake systems and is catalogued as part number XN1-47/RE. The 21-tooth pulley is a direct-replacement item that helps maintain steady actuation and supports fine adjustment of pedal characteristics on road and track models.

Fitment pointers: remove the existing pulley using normal model servicing procedures, inspect adjacent 走珠軸承 and the brake arm for wear, align the new pulley correctly with the braking cable or linkage, and tighten fixings to the recommended setting without overtightening. For model use only.

Setup guidance: swapping the pulley can influence engagement timing and consistency. Use it to refine lever geometry, reduce unwanted free play in linkages, and pair with routine bearing maintenance and lubrication to keep braking predictable.
