When to Replace
- Rotor thickness measures below the minimum wear limit (typically stamped on the rotor, e.g., 1.5mm).
- Visible signs of significant warping, cracking, or deep scoring are present.
- Braking performance is diminished or feels inconsistent (pulsing).
- Persistent brake noise that cannot be resolved by cleaning, pad replacement, or caliper alignment.
Installation Tips
- Ensure hub mounting surface is clean and flat before installing.
- Tighten mounting bolts incrementally in a star pattern to the manufacturer’s recommended torque specification.
- Clean the rotor surface with isopropyl alcohol after installation to remove any oils or contaminants.
- Properly bed-in new rotors with brake pads to achieve optimal braking performance.
- Check for proper caliper alignment and clearance after installation.
