Brake Kit for Ford Ranger and Aerostar

DFC Friction part 4512-99107 is a front disc brake kit built for select Ford Ranger, Ford Aerostar, and Mazda B-Series applications. It combines GEOSPEC coated rotors, 5000 Advanced ceramic brake pads, and matching hardware for a complete front brake service.

Key Features

• GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
• Dry-processed rotors that are ready to install without oil removal
• G3000/G11H18 cast iron rotor construction for OE-style durability and stability
• Non-directional rotor finish for even pad bed-in and smoother braking
• 5000 Advanced ceramic pads with post-cured friction material
• Scorched pads to reduce initial break-in time and improve first-stop response
• Rubber-steel-rubber shims for improved noise, vibration, and harshness control
• Hardware designed with PTFE coating, vulcanized rubber, and stainless steel

Product Details

The DFC GEOSPEC Coated Rotors with 5000 Advanced Brake Pads - Ceramic and Hardware line is engineered for drivers who want a front brake service package with OE-style fit, consistent friction, and corrosion protection. The coated rotor surface helps resist rust, while the machined finish supports quieter stops and more even pad contact. The 5000 Advanced pad formulation is developed for stable braking performance across a wide range of passenger and light truck applications, including Ford Ranger front brake replacement and Ford Aerostar front brake repair.

Part number 4512-99107 is also a practical choice for Mazda B2300, B3000, and B4000 front brake service where the listed rear drum configuration matches the fitment notes. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Brake noise from worn pads or fatigued hardware
• Uneven pad wear caused by caliper movement or weak hardware tension
• Rust buildup on exposed rotor surfaces
• Longer stopping distances from worn front brake components
• Vibration or rough brake feel during normal stops
