Dynamite Friction 4504-31004 Disc Brake Kit - Front and Rear

Brake Kit for BMW 318i, 325i, 328i

Dynamite Friction DFC GEOSPEC Rotors with 5000 Advanced Brake Pads, part number 4504-31004, is a complete disc brake kit for front and rear service on select BMW 3 Series models. It combines coated rotors and matched pads in one package for a straightforward brake replacement on 1991-1999 BMW 318i, 318is, 325i, 325is, 328i, and 328is applications.

Key Features

• Complete front and rear disc brake kit
• DFC GEOSPEC coated rotors with silver-gray corrosion-resistant finish
• Dry-processed rotors ship ready to install
• Non-directional rotor finish for even pad bed-in and smoother braking
• G3000/G11H18 cast iron rotor specification for OE-style durability and stability
• DFC 5000 Advanced pads are post-cured and scorched for stable friction performance
• Premium rubber-steel-rubber shims help reduce noise, vibration, and harshness

Product Line Details

The DFC GEOSPEC rotor line focuses on corrosion protection and installation efficiency. The coated surface helps resist rust better than conventional paint or zinc finishes, while the dry rotor process eliminates the need to clean off oil before installation. The 5000 Advanced pad line is built around consistent friction behavior, with post-curing and scorching steps used to reduce initial break-in time and improve stopping response from the first stop.

Detailed Description

Part number 4504-31004 is a brake service kit engineered for BMW 318i, 318is, 325i, 325is, 328i, and 328is models from 1991 through 1999, including 1991 vehicles built from 11/91. The kit pairs DFC GEOSPEC coated rotors with DFC 5000 Advanced brake pads to provide a matched replacement solution for front and rear brake service. Each rotor is machined to tight tolerances, finished with a non-directional surface, and inspected for critical dimensions and balance. The pads are formulated for stable friction characteristics and assembled with noise-reducing shims for quieter operation.

Common Brake Issues This Kit Can Address

• Rusty or corroded brake rotors
• Brake pulsation from worn or uneven rotor surfaces
• Squeal or noise from aged pad and shim assemblies
• Reduced stopping performance from worn friction material
• Longer service time caused by oil-coated replacement rotors

Installation Notes and Tips

• Verify vehicle production date on 1991 BMW 318i and 318is models; this kit applies to vehicles built from 11/91.
• Inspect calipers, hoses, and hardware condition before installation.
• Follow proper rotor and pad bed-in procedures after installation.
• Clean hub surfaces thoroughly to help prevent rotor runout and uneven pad wear.
• Confirm front and rear brake dimensions against the vehicle before service.

Quality Assurance

DFC GEOSPEC rotors are processed through machining and inspection steps that check critical attributes against OE specifications. Vented rotors are electronically mill-balanced when needed, and each rotor is backed by a 12-month warranty against defects in material and workmanship. The 5000 Advanced pads are post-cured, scorched, and fitted with premium shims to support consistent performance and NVH control.
