Precision replacement rotor for Savage 21

A steel replacement brake disk prepared for use on HPI Savage 21 style chassis, the rotor is intended to provide consistent geometry for brake maintenance and setup procedures.

Installation overview: remove the wheel and original rotor, locate the replacement disk in the factory orientation and secure hub fasteners to the specified fitment. Verify radial and lateral runout and confirm pad engagement before operation.

Service and setup considerations: the steel disc gives repeatable wear characteristics that simplify brake feel adjustments and service intervals. Inspect for scoring, heat signs or uneven wear and include the rotor in routine brake system checks.

How should runout be checked after fitment?

Mount the wheel assembly and use a dial indicator or a fixed pointer to measure lateral deviation while rotating; adjust seating or replace components if runout exceeds service limits.

What inspection points are critical for steel rotors?

Check for radial runout, surface scoring, and uneven wear across the pad contact area; confirm hub fastener torque and that the rotor sits flush on the hub face.

Any recommended break-in or bedding procedure?

Perform a series of controlled low-speed stops to bed pads to the rotor surface, then recheck pad alignment and fastener torque before full-speed runs.
