Dynamic Friction 4504-39003 Front and Rear Geospec Brake Rotor and Pad Kit

The Dynamic Friction 4504-39003 is a complete front and rear brake kit that combines advanced corrosion protection with precision-engineered stopping power. This comprehensive package includes four Geospec coated brake rotors and eight 5000 Advanced brake pads designed to work together as a matched braking system.

Geospec Corrosion Protection Technology:

• Proprietary coating creates a durable silver-gray finish that resists rust far better than conventional paint or zinc coatings
• Rotors arrive processed dry and shipped dry—ready to install without cleaning oil-covered surfaces
• Coating is safely swept away by friction material during initial use with no harmful effects
• Non-directional rotor finish promotes faster, more even brake pad bed-in for quieter and smoother stops

Premium Rotor Construction:

• Engineered with premium G3000/G11H18 iron castings for superior strength, stability, and durability
• 100% precision mill-balanced for smoother stopping and zero vibration at any speed
• Machined to the tightest tolerances available for consistent performance
• Designed to meet the same form, fit, and function as OEM brake rotors

5000 Advanced Brake Pads:

• Application-specific friction formulation tuned for modern vehicles with ABS and automated braking systems
• Chamfered and slotted (where applicable) to reduce noise when braking
• Scorched to remove uncured bonding agents, minimizing break-in period and increasing stopping power from the initial stop
• Positive mold process promotes consistent friction material density throughout the pad
• Rotor-friendly formula provides proven longer rotor and pad life
• Environmentally friendly and adheres to low copper requirements under California and Washington restrictions
• Delivers consistent pedal feel and superb brake response

This complete brake kit simplifies the parts selection process by providing a system-matched approach with components specifically engineered to work together for optimal braking performance, reduced noise, and extended service life.
