Dynamite Friction 4312-48022 Disc Brake Kit - Rear

Rear Brake Kit for GM Trucks and SUVs

The Dynamite Friction DFC GEOSPEC Coated Rotors with 3000 Ceramic Brake Pads and Hardware Kit, part number 4312-48022, is a rear disc brake kit built for select GM trucks and SUVs. It combines coated rotors, ceramic pads, and brake hardware for a complete rear brake service on supported applications.

Compatible With 1999-2007 Chevrolet Silverado 1500, Chevrolet Avalanche 1500, Chevrolet Suburban 1500, Chevrolet Tahoe, GMC Sierra 1500, GMC Yukon, GMC Yukon XL 1500, Chevrolet Astro, and GMC Safari rear brake applications listed below.

Key Features

• DFC 3000 ceramic brake pads for stable friction across a wide temperature range
• Low-dust pad formulation for cleaner wheel maintenance
• Post-cured and scorched pads to reduce initial break-in time
• Premium rubber-steel-rubber shims for improved noise, vibration, and harshness control
• GeoSpec coated rotors with a silver-gray finish that resists rust better than conventional paint or zinc coatings
• Dry-packaged rotors ready to install without oil removal or extra prep
• G3000/G11H18 cast iron rotor construction machined to OE-style tolerances
• Non-directional rotor finish for smoother bed-in and quieter braking

Product Line Details

DFC GEOSPEC coated rotors are designed for corrosion resistance and consistent installation. The coating is applied to protect the rotor surface, while the dry-shipped design saves prep time during brake service. DFC 3000 ceramic pads are formulated for passenger vehicles and light-duty trucks, with attention to fade resistance, low dust, and stable pedal feel.

Detailed Description

Part number 4312-48022 is a rear brake service kit for select Chevrolet and GMC platforms, including rear brake service on 1999-2002 Chevrolet Silverado 1500, 2000-2002 Chevrolet Suburban 1500, 2001-2002 Chevrolet Tahoe, 1999-2002 GMC Sierra 1500, 2000-2002 GMC Yukon, 2000-2002 GMC Yukon XL 1500, 2003-2005 Chevrolet Astro, 2003-2005 GMC Safari, and 2005-2007 GMC Sierra 1500 applications shown in the fitment list. The coated rotors are machined, balanced where required, and finished for even pad contact, while the ceramic pads are built for reliable stopping performance and reduced brake noise.

This part number 4312-48022 is a practical choice for rear brake repair when the goal is to restore braking response, reduce rotor corrosion, and replace worn friction components in one service. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Brake noise from worn pads or fatigued hardware
• Uneven rear braking caused by rotor wear or corrosion
• Excessive brake dust buildup on wheels
• Longer stopping distances from worn friction material
• Brake pulsation related to rotor surface condition

Installation Notes and Tips

• Verify rear axle, caliper, and steering notes before ordering; several applications exclude Heavy Duty, Limited, or Limited Slip configurations.
• Inspect calipers, slides, and parking brake components during service to confirm proper operation.
• Clean rotor surfaces only as needed before installation; GeoSpec rotors are shipped dry and ready to install.
• Follow a proper pad bed-in procedure after installation to promote even transfer and consistent braking.

Quality Assurance

DFC GeoSpec rotors are manufactured to OE-style specifications, inspected for critical dimensions, and backed by a 12-month warranty against defects in material and workmanship. The brake pads are post-cured and scorched for stable friction performance, and the hardware kit uses PTFE coating, vulcanized rubber, and stainless steel for corrosion resistance and fit consistency.
