Dynamic Friction Company Disc Brake Rotor P/N:900-54278
Keep your rear brakes biting cleanly with the Dynamic Friction Company GEOSPEC Coated Disc Brake Rotor 604-54278 — a direct-fit Ford Explorer brake rotor built for the rear axle of the 2020-2026 Ford Explorer, 2024-2025 Ford Mustang, 2020-2026 Ford Police Interceptor Utility and 2020-2026 Lincoln Aviator. See the Buyer's Guide tab for the engine-level fitment for your vehicle.
The non-directional finish promotes faster pad break-in, and this DYNAMIC FRICTION brake rotor ships ready to install with no pre-degreasing needed. It's designed to meet the same form, fit, and function as the OEM rotor. A warped or scored rotor can cause brake pedal pulsation or vibration; if a worn rear rotor is the cause, this replaces it. Because rotors wear together, replace both rear sides as a matched pair — and inspect your Ford Explorer brake pads and rotors at the same time — for even, balanced braking. Sold individually; order two for a complete rear-axle replacement.
Will this rotor fit my Ford Mustang?
Yes — this Ford Mustang brake rotor fits the rear axle of the 2024-2025 Ford Mustang, plus the 2020-2026 Ford Explorer, Police Interceptor Utility and Lincoln Aviator. Check the Buyer's Guide tab for your engine.
Is this a front or rear rotor?
It is a rear-axle rotor for the listed applications.
Do I need to replace both rear rotors?
Rotors wear together, so replacing both rear sides as a matched pair is recommended for even, balanced braking. It's sold individually, so order two for the axle.
What is the GEOSPEC coating?
It's DFC's protective rotor coating that provides corrosion protection beyond zinc and conventional painting.
Do I need to clean the rotor before installing?
No — it ships ready to install with a non-directional finish and needs no additional pre-degreasing preparation before it goes on.
