Dynamite Friction 4512-63121 Disc Brake Kit - Front

Brake Kit for Mercedes-Benz Front Applications

The DFC GEOSPEC Coated Rotors with 5000 Advanced Brake Pads and hardware kit is built for front brake service on select Mercedes-Benz models from 1979-1985. Part number 4512-63121 combines coated rotors, ceramic brake pads, and brake hardware in one service kit for a direct brake refresh.

Compatible With Mercedes-Benz 300SD, 380SE, 380SEL, and 500SEL front brake applications, this kit is designed for vehicles with the listed Bendix or Girling caliper configurations. If you are servicing a Mercedes-Benz 300SD front brake job or replacing worn front brake components on a 380SE, 380SEL, or 500SEL, 4512-63121 provides the matched parts needed for the axle.

Key Features

• DFC GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
• 5000 Advanced ceramic brake pads with post-cured friction material
• Scorched pads to reduce initial break-in time
• Premium rubber-steel-rubber shims for improved noise and vibration control
• Brake hardware with PTFE coating, vulcanized rubber, and stainless steel construction
• Rotors machined to OE-style tolerances with a non-directional finish
• Dry-processed rotors ready for installation

Product Details

DFC’s GEOSPEC rotor coating is engineered to resist rust better than conventional paint or zinc finishes, while the dry packaging helps eliminate the need to clean oil from the rotor before installation. The rotors are cast to G3000/G11H18 specifications, machined for tight tolerances, and inspected for balance and critical dimensions. The 5000 Advanced pads are formulated for stable friction performance and consistent stopping response, while the included hardware is designed to restore proper spring tension and caliper movement during brake service.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Brake Kit Helps Address

• Front brake noise from worn pads or fatigued hardware
• Uneven pad wear caused by corroded or weakened brake clips
• Reduced stopping performance from worn rotors and friction material
• Brake vibration or rough pedal feel during deceleration
• Extended service time caused by rotors that require cleaning before installation
