Front Brake Pad & Rotor Kit for 2003-2009 GX470 4Runner - Complete

In this review of the TRQ Front Brake Pad & Rotor Kit, the bottom line is simple: this kit is for owners who want a complete, direct-fit front brake replacement that bundles pads, calipers and vented rotors for a straightforward DIY job. The biggest reason to buy is the convenience of receiving matching front semi-metallic pads, two front calipers and two 338mm vented rotors that are pre-assembled for typical 2003-2009 Lexus GX470 and Toyota 4Runner front applications. The reviewer found the kit saves install time and avoids compatibility guesswork when the vehicle matches the listed caliper casting and rotor diameter.

Key Features

• Complete Front Kit: Includes a front semi-metallic brake pad set, two front brake calipers and two front brake rotors so installers get all primary front hardware in one purchase.
• Semi-Metallic Pads: The premium semi-metallic friction material delivers predictable stopping performance and improved heat handling for daily driving and towing duties.
• 338mm Vented Rotors: Rotor diameter of 13.31 in (338mm) with vented design helps dissipate heat and reduce fade under repeated braking.
• Direct Fit Design: Application specific castings and pre-assembled components minimize modification and speed up installation for compatible 2003-09 models.
• Built for Quiet Operation: Positive molded pads and a G3000 casting alloy are intended to reduce noise and lower dust for cleaner wheels.

Who It's For

This kit is best for owners of 2003-2009 Toyota 4Runner and Lexus GX470 who require front brake service and who can confirm fitment with the caliper casting #13WH or the specified 338mm rotor size. It suits DIY mechanics who prefer a single packaged solution that replaces pads, calipers and rotors at once, reducing parts matching and installation time.

It is less appropriate for drivers who demand long-term racing-grade longevity or want an all-ceramic pad compound, as the kit uses semi-metallic pads focused on balanced performance and wear. Also confirm exact vehicle fitment before buying, since this kit targets the specified front caliper casting and rotor diameter.

Pros & Cons

Pros
