Rear Brake Pad & Rotor Kit for 1999-2003 Lexus RX300 - Complete Rear

In this review of the Rear Brake Pad & Rotor Kit for the 1999-2003 Lexus RX300, the bottom line is simple: this kit is best for DIYers and independent shops wanting a full rear brake refresh with ceramic pads, rotors, parking shoes and chemicals included. The kit stands out because it bundles DOT 3 and DOT 4 compatible chemicals with positive molded ceramic pads and paired rotors, so a single purchase can restore braking feel and reduce dust without hunting down separate components.

Key Features

• Complete rear kit: Includes rear ceramic brake pads, rear rotors, parking brake shoes and a brake cleaner and fluid kit so users get everything needed for a rear brake job in one package.
• Ceramic pad material: Positive molded ceramic friction material reduces dust and provides consistent stopping performance under normal driving conditions.
• Rotors with G3000 casting alloy: Rotors are cast for reduced noise and improved wear resistance compared with generic castings.
• Chemical specifications: The included brake cleaner and fluid kit is compatible with DOT 3 and DOT 4 systems for safe, correct flushing and topping up during installation.
• Application specific design: Components are designed for the 1999-2003 Lexus RX300 AWD rear axle, which helps reduce or eliminate fitment changes and extra machining for most installs.

Who It's For

This kit is aimed at Lexus RX300 owners from model years 1999 through 2003 who want to replace the entire rear braking system themselves or have a single service visit replace pads, rotors and parking shoes. It suits DIY mechanics who value lower dust from ceramic pads and the convenience of a bundled chemical kit for cleaning and brake fluid needs.

Those who should look elsewhere include owners who require high-performance or heavy towing brake compounds, and buyers with RX300s that have nonstandard or modified rear hubs-some customers reported mixed fit experiences so verifying fit before installation is advised.
