Brembo 09.C251.21 Disc Brake Rotor - Front

Overview

Brembo 09.C251.21 is a vented disc brake rotor built as a direct replacement for the specified application. It combines a UV-coated surface with high carbon cast iron construction to support quieter braking, reduced vibration, and corrosion protection on the braking surfaces.

Fits 2008-2011 Ford Focus, front. This rotor is also identified by part number 09.C251.21 for catalog and cross-reference use.

Key Features

• UV-coated finish helps protect the rotor surface and braking plate surfaces.
• High carbon cast iron construction supports noise and vibration control.
• Vented rotor design promotes consistent braking performance.
• Direct replacement format meets or exceeds OEM specifications.
• Intelligent marking shows the part number and minimum thickness.

Detailed Description

The Brembo Premium UV Coated OE Equivalent Rotor line focuses on OE-style replacement parts with practical durability features. For this Ford Focus brake rotor application, the vented design, 275 mm outside diameter, 4-hole pattern, and 63.6 mm centering diameter align with the listed fitment and braking requirements. Brembo 09.C251.21 is intended for drivers replacing a worn front disc brake rotor while maintaining factory-style braking feel and serviceability.

This part cross-references Centric Parts (e.g., 120.61093, 121.61093) for the same application.

What It Helps Address

• Brake pulsation from a worn or uneven rotor surface.
• Noise and vibration during normal braking.
• Corrosion on exposed rotor surfaces.
• Reduced braking consistency from rotor wear below minimum thickness.

Installation Notes and Tips

Fits 2008-2011 Ford Focus, front. Verify rotor thickness before installation; the minimum thickness is 23 mm and nominal thickness is 25 mm. Brembo recommends replacing rotors and pads together to restore braking performance. Pairing with Brembo NAO/Ceramic or Low Met brake pad formulations is recommended for this rotor family.

Quality Assurance

Brembo states that this rotor is developed as a direct replacement that meets or exceeds OEM specifications. The UV coating is solvent free, and the brand identifies this rotor line as an OE equivalent replacement.
