This item is a steel brake rotor tailored as an RC-scale replacement for the HPI Savage 21 chassis, intended for direct swap-in maintenance and setup work on models referencing the Savage 21.
Installation overview: take off the wheel and worn rotor, locate the new steel disk in the original orientation, and tighten the hub fasteners to the recommended fit. Once fitted, run a rotor alignment check and confirm the pads seat correctly before first use.
Tuning role and durability: as a steel rotor it gives steady, predictable wear that assists with brake feel adjustments during setup. Inspect for scoring or uneven wear and plan replacements as part of your regular upkeep.
