2005-2023 Toyota Tacoma Rear Disc Brake Conversion Kit Overview

The factory drum brakes on 2005-2023 Toyota Tacomas are not ideal once you add larger tires and the extra weight of overlanding gear. This Trail Gear rear disc brake conversion kit replaces those drums with GM-style floating calipers and custom vented rotors made for this Toyota swap.

Disc brakes are easier to maintain and simpler when it is time to replace the pads. The brackets are 3/8" CNC laser-cut steel, the calipers ship loaded, and the included DOT-approved brake lines adapt the GM calipers to your OEM Toyota hard lines, so no conversion fittings are required.

What's Included

• 3/8" CNC laser-cut caliper brackets (ship raw/unpainted) with grade 10.9 bolts
• GM-style floating calipers, shipped fully loaded
• Custom-made GM-style vented rotors
• DOT-approved brake lines (GM caliper fitment on one end, OEM Toyota hard-line fitment on the other)
• Zinc-plated hardware
