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.\u003c\/p\u003e\u003ch2\u003eDetailed Description\u003c\/h2\u003e\u003cp\u003ePart 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.\u003c\/p\u003e\u003ch2\u003eCommon Brake Issues This Kit Can Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRusty or corroded brake rotors\u003c\/li\u003e\n\u003cli\u003eBrake pulsation from worn or uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eSqueal or noise from aged pad and shim assemblies\u003c\/li\u003e\n\u003cli\u003eReduced stopping performance from worn friction material\u003c\/li\u003e\n\u003cli\u003eLonger service time caused by oil-coated replacement rotors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eVerify vehicle production date on 1991 BMW 318i and 318is models; this kit applies to vehicles built from 11\/91.\u003c\/li\u003e\n\u003cli\u003eInspect calipers, hoses, and hardware condition before installation.\u003c\/li\u003e\n\u003cli\u003eFollow proper rotor and pad bed-in procedures after installation.\u003c\/li\u003e\n\u003cli\u003eClean hub surfaces thoroughly to help prevent rotor runout and uneven pad wear.\u003c\/li\u003e\n\u003cli\u003eConfirm front and rear brake dimensions against the vehicle before service.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDFC GEOSPEC rotors are processed through machining and inspection steps that check critical attributes against OE specifications.
