Dynamite Friction 4302-73004 Disc Brake Kit - Rear

Rear Brake Kit for Audi Q3

Dynamite Friction DFC GEOSPEC Rotors with 3000 Ceramic Brake Pads, part number 4302-73004, is a rear disc brake kit built for 2016-2018 Audi Q3 and 2016-2018 Audi Q3 Quattro applications. It combines coated rotors and ceramic pads in one service package for a direct brake refresh on the rear axle.

Key Features

• Fits 2016-2018 Audi Q3, rear
• Fits 2016-2018 Audi Q3 Quattro, rear
• DFC GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
• Dry rotor processing for installation without additional cleaning prep
• Non-directional rotor finish for more even pad bed-in and smoother braking
• DFC 3000 ceramic pads for low dust, stable friction, and fade resistance
• Post-cured and scorched pads to reduce break-in time
• Rubber-steel-rubber shims for improved noise, vibration, and harshness control

Product Details

The DFC GEOSPEC rotor design uses G3000/G11H18 cast iron and is machined to tight tolerances to match OE-style durability and stability. The coated surface helps resist rust better than conventional paint or zinc finishes, while the dry-ready rotor format saves time during brake service. The 3000 Ceramic pads are formulated for passenger vehicles and light-duty trucks, with consistent friction across a wide temperature range and low-copper compliance for California and Washington requirements.

This part number, 4302-73004, is a practical rear brake solution for Audi Q3 and Audi Q3 Quattro owners looking to replace worn rear rotors and pads together. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Issues It Can Address

• Rear brake pulsation from worn or uneven rotors
• Brake noise caused by pad wear or inconsistent contact surfaces
• Excess brake dust from aging friction material
• Reduced stopping consistency during heat buildup
• Rust on exposed rotor surfaces after long service intervals

Installation Notes

Install on the rear axle only for the listed Audi Q3 and Audi Q3 Quattro model years. Clean the rotor friction surfaces before assembly if needed, and follow standard brake service procedures for pad bedding and torque specifications. The rotors are shipped dry and ready to install, which reduces prep time during a rear brake job.

Quality Assurance

Each rotor is 100% inspected for critical dimensions and balance, with vented rotors corrected through electronic mill-balancing when required. DFC states that every rotor is checked against OE specifications, and the rotors include a 12-month warranty against defects in material and workmanship.
