Dr. Rex from the R1 Crew recently upgraded one of our ambassador builds, Tiffany’s third-generation Toyota Tacoma, with a full rear disc brake conversion using our CUSTOM Big Brake Kit. This upgrade is more than cosmetic. It provides real stopping power, better performance, and a modern look that matches today’s driving demands.
This blog walks through the installation process, why rear drum brakes fall short, and how R1 Concepts offers a tailored solution for 2016 to 2023 Tacomas.
Toyota continues to equip many Tacoma models with rear drum brakes. While they are inexpensive to manufacture, they are outdated in performance and design. For Tacoma owners who are modifying their trucks for overlanding, towing, or off-road use, drum brakes quickly become a weak point.
In the video, Dr. Rex points out that the factory drum system uses a simple wheel cylinder and brake shoes that expand outward to stop the vehicle. While functional, the design lacks the power and heat management needed for modified vehicles or heavier loads. Drum brakes also tend to be more difficult to maintain and less responsive under repeated use.
To fix this, Tiffany’s Tacoma was outfitted with the R1 Concepts four-piston rear Big Brake Kit. Designed specifically for third-generation Tacomas from 2016 through 2023, this kit replaces the outdated drum setup with a high-performance rear disc system.
Key features of the Big Brake Kit include:
For optimal performance, this kit can be paired with our R1 PERFORMANCE Off-Road/Tow Series Brake Pads or R1 CERAMIC Series Brake Pads depending on your driving needs.
Pro tip: When bleeding the brake system, always begin with the caliper farthest from the master cylinder to ensure proper air removal.
While most braking force comes from the front, rear brakes play a critical role in stability and load handling. Upgrading from drums to discs provides several benefits:
This upgrade is especially valuable for Tacoma owners who have added larger wheels, rooftop tents, trailers, or other heavy accessories.
