Brembo 01-06 LS430 Rear GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Drilled-Silver

This Brembo GT Big Brake Kit for the rear of your 2001-2006 Lexus LS430 includes everything you need to significantly upgrade your braking system. You get a pair of four-piston cast aluminum calipers, two-piece 345x28mm rotors that are drilled and silver, and all the necessary hardware for installation. This kit is designed to replace your factory rear brake components with a much more robust setup, offering improved stopping power and heat management.

The calipers are a four-piston design, which means more clamping force is applied to the rotor surface compared to a typical two-piston factory caliper. They are cast from aluminum, keeping unsprung weight down while maintaining solid structural integrity. The rotors are a two-piece design, featuring a cast iron braking surface attached to an aluminum hat. This construction helps reduce heat transfer to the hub and allows for more precise rotor runout. The 345mm diameter and 28mm thickness provide a larger surface area for heat dissipation and increased leverage. The drilled pattern on the rotors helps to vent gases and moisture away from the pad surface, which can improve braking consistency, especially under heavy use.

Installing a big brake kit like this is a substantial upgrade that can make a noticeable difference in how your LS430 performs under braking, particularly if you frequently carry heavy loads or drive in demanding conditions. It's a well-built system from Brembo, a name known for its high-performance braking components. Ensure you have the proper tools and refer to the manufacturer's installation guide for detailed instructions, as this is a significant modification to your vehicle's braking system.
