Dynamite Friction 4502-75037 Disc Brake Kit - Rear

Rear Brake Kit for Lexus GS, IS300, and SC430

The Dynamite Friction DFC GEOSPEC Rotors with 5000 Advanced Brake Pads kit is a rear disc brake service solution for select Lexus applications. Part number 4502-75037 combines coated rotors and matched friction material to support consistent braking performance, cleaner installation, and OE-style fitment.

Key Features

• Rear disc brake kit with rotors and pads in one package
• DFC GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
• Dry-processed, dry-shipped rotors ready for installation
• G3000/G11H18 cast iron rotor specification for OE-style durability and stability
• Non-directional rotor finish for more even pad bed-in and smoother braking
• 100% inspected rotors with balance correction on vented units
• 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

DFC GEOSPEC rotors are engineered for corrosion resistance and straightforward service work, while the 5000 Advanced pad line is formulated for stable friction across a range of passenger car and light truck applications. Together, they provide a matched rear brake service kit for drivers looking to replace worn components with OE-style parts.

Detailed Description

Part number 4502-75037 is built for rear brake service on 1998-2000 Lexus GS400, 1998-2005 Lexus GS300, 2001-2005 Lexus GS430, 2001-2005 Lexus IS300, and 2002-2010 Lexus SC430. This kit is a practical choice when replacing rear rotors and pads on a Lexus GS300 rear brake kit application, a Lexus IS300 rear disc brake kit, or a Lexus SC430 rear brake service job. The coated rotors are machined to tight tolerances and finished to promote quieter stops and faster pad bedding, while the pads are prepared to reduce initial break-in time and deliver stable friction from the first stop.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Rear brake noise during stopping
• Rotor rust and surface corrosion
• Uneven pad bedding after brake service
• Brake vibration caused by worn or out-of-spec rear components
• Reduced stopping consistency from aged pads and rotors

Installation Notes and Tips

These rotors are processed dry and ready to install, which helps reduce prep time during service. Clean the rotor friction surfaces before assembly, follow the vehicle manufacturer’s brake service procedure, and verify rear brake fitment by model year before installation. Part number 4502-75037 is a rear-position kit only.

Quality Assurance

Each rotor is inspected for critical dimensions and balance, and all vented rotors are checked for balance correction when needed. DFC states a 12-month warranty against defects in material and workmanship for the rotors included in this kit.
