Product Description

The Brembo KT04346 PRIME Rear Disc Brake Kit combines two 09.A182.21 UV-coated ventilated rear rotors with a P11024 PRIME low-metallic brake pad set. Designed for compatible Chrysler 300, Dodge Charger, and Dodge Challenger applications equipped with the BR4 performance rear brake system, the kit provides a matched solution for complete rear-axle brake service.

The 09.A182.21 rotors measure 350 mm in diameter, 28 mm in nominal thickness, and 68 mm in height, with a 73 mm center bore and five mounting holes. High-carbon cast-iron construction supports heat conduction and vibration damping, while the ventilated design promotes cooling. Brembo's UV coating protects exposed surfaces against corrosion, and the slotted friction surface supports consistent pad contact.

The P11024 PRIME low-metallic pads measure 109.8 mm wide, 69.2 mm high, and 14.8 mm thick. Brembo specifies an OE-equivalent low-metallic formulation with premium shims and an acoustic wear indicator. KT04346 is verified for selected 2010-2020 Chrysler 300, 2010-2020 Dodge Charger, and 2011-2020 Dodge Challenger applications. Confirm the vehicle's BR4 brake code and 350 mm rear rotor configuration before installation.
