2022-2026 Toyota Tundra (XK70) & 2023-2026 Toyota Sequoia (XK80) OR6 Direct-Mount Front Big Brake Kit
The TTSPORT OR6 Front Big Brake Kit is built for loaded Toyota Tundra (XK70) and Sequoia (XK80) platforms running larger tires, armor, recovery gear, roof tents, and trailer weight. A 6-piston forged caliper, Ø345 mm × 34 mm one-piece high-carbon iron rotor, and PTFE/SUS304 braided lines deliver firmer pedal feel and more predictable control on long descents, washboard, and slow-speed technical terrain.
Why Toyota Tundra XK70 & Sequoia XK80 Builders Choose the OR6
Predictable Off-Pavement Modulation
6-piston layout with 40 mm × 4 and 43 mm × 2 pistons supports smooth pressure build on gravel, dirt, and low-traction surfaces.
Application-Correct Rotor Size
Toyota Tundra (XK70) and Sequoia (XK80) use the OR6 Ø345 mm × 34 mm front rotor specification.
Stable Pedal Under Heat
One-piece heat-insulated pistons with dust boots help resist fluid temperature rise during sustained braking.
Consistent Line Pressure
Three-layer PTFE / SUS304 braided lines reduce expansion under load for a firmer pedal.
Direct-Mount Fitment
Vehicle-specific direct-mount configuration for Toyota Tundra XK70 and Sequoia XK80 front-axle applications.

Thought provoking, beautiful poetry on life.
Format: Paperback
This book is small, but powerful. The writing is poetic indeed, which can make it hard to read (I had to reread sentences constantly to understand). But it is WELL worth the effort.
Beautiful writing. Beautiful concepts.
