Dynamite Friction 4502-31191 Disc Brake Kit - Rear

Rear Brake Kit for BMW X1 and 3 Series

Dynamite Friction DFC GEOSPEC Rotors with 5000 Advanced Brake Pads, part number 4502-31191, is a rear disc brake kit built for specific BMW applications. It combines coated rotors and matched brake pads in one service package for rear brake replacement on select BMW X1 and 3 Series models.

Key Features

• Rear disc brake kit with rotors and pads
• DFC GEOSPEC coated rotors with silver-gray corrosion-resistant finish
• Dry-packed rotors ready for installation without extra cleaning
• Non-directional rotor finish for even pad bed-in and quieter stops
• 5000 Advanced pads with post-cured friction material
• Scorched pad surface to reduce initial break-in time
• Rubber-steel-rubber shims for improved NVH control
• OE-spec cast iron rotor construction and tight machining tolerances

Product Details

The DFC GEOSPEC rotor and 5000 Advanced pad combination is engineered for rear brake service on 2006-2015 BMW X1, 2006-2013 BMW 330i and 330xi, 2007-2013 BMW 335i and 335xi, 2008-2009 BMW 325i, 2008 BMW 335xi, 2009-2013 BMW 335i xDrive, 2009-2011 BMW 335d, and 2011-2013 BMW 335is. This part number, 4502-31191, uses coated rotors to help resist rust while the pad formulation is processed for stable friction performance and smoother operation. The rotor finish and pad preparation support consistent braking response during routine rear brake service on BMW X1 and BMW 3 Series vehicles.

What It Helps Address

• Rear brake noise during stopping
• Rotor surface rust and corrosion buildup
• Uneven or rough brake feel
• Extended pad break-in after service
• Brake vibration related to worn rear components

Installation Notes

Compatible With rear brake service only. Each rotor is processed dry and ready to install, which reduces prep time during brake work. The non-directional finish supports faster pad bed-in, and the pad shims are used to improve noise and vibration control. Verify rotor size, caliper setup, and vehicle production date before installation, especially on 2007 BMW 335xi applications with production-date notes. Part number 4502-31191 is intended for the listed rear applications only.

Quality Assurance

DFC states that each rotor is machined to OE specifications, inspected for critical dimensions, and balanced where required. The rotors carry a 12-month warranty against defects in material and workmanship. The 5000 Advanced pads are post cured and scorched for stable friction characteristics, and the complete kit is assembled to provide matched rear brake components in one package.
