Brembo 09.A183.21 Disc Brake Rotor - Front

Overview

Brembo PRIME UV Coated disc brake rotor, part number 09.A183.21, is built for front brake applications that demand consistent braking feel and stable heat management. It is a vented, full-cast rotor made from high carbon cast iron with a coated brake surface for added corrosion resistance.

Key Features

• High carbon cast iron construction for thermal stability under repeated braking.
• Vented rotor design helps move heat away from the braking surface.
• Coated brake surface supports corrosion resistance on exposed metal areas.
• Full cast construction with a smooth surface finish.
• Premium-grade rotor engineered for direct replacement use.

Detailed Description

This Brembo rotor is part of the PRIME UV Coated line, a product family focused on coated braking components for cleaner appearance and added surface protection. The rotor uses a full-cast, vented design with a 360 mm outside diameter, 32 mm nominal thickness, and 30 mm discard thickness. The 73 mm center hole and 5-lug pattern align with the listed applications, including Dodge Challenger, Dodge Charger, Chrysler 300, and Dodge Magnum front brake fitments. Part number 09.A183.21 is a practical choice for drivers replacing worn front rotors on these platforms.

Common Issues It Can Address

• Brake pulsation caused by rotor wear or thickness variation.
• Reduced braking consistency from heat buildup in the rotor.
• Surface corrosion on exposed rotor areas.
• Noise or rough braking feel from worn braking surfaces.
• Loss of braking performance from rotors that have reached discard thickness.

Installation Notes and Tips

Verify rotor dimensions, hub fitment, and brake package details before installation. This rotor is listed for front applications only, and fitment includes Dodge Challenger, Dodge Charger, Chrysler 300, and Dodge Magnum models across the years shown. Always inspect pads, calipers, and hub surfaces during brake service to help ensure even contact and proper rotor seating.

Quality Assurance

Brembo is known for braking components supplied to OE and aftermarket applications, and the PRIME UV Coated line focuses on coated rotor protection and consistent manufacturing standards. Part number 09.A183.21 is cross-referenced to Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
