GWM Tank 500 Big Brake Kit Upgrade / TTSPORT Direct-Mount OR6
The Tank 500 was never built as a city commuter. It's a heavy, four-wheel-drive SUV that gets loaded up, hitched to trailers, and pointed down long descents and rough, unpaved trails — conditions that put far more demand on a brake system than everyday street driving. If a loaded Tank 500 feels short on confidence on a long grade, if the pedal goes soft after repeated braking, or if the factory brakes feel inconsistent over gravel and washboard, that's a sign the stock hardware is working near its limit. This case looks at a Tank 500 fitted with the TTSPORT OR6, a direct-mount six-piston kit built specifically for heavy-duty, off-road use.
The OR6 caliper bolts to the Tank 500's factory mounting points with no flange adapter and no drilling — the kind of clean, reversible install off-road owners actually want, since it doesn't compromise the vehicle's structure or complicate future service.

Why It Works
The OR6 isn't just a six-piston caliper bolted on for the sake of a bigger number. Piston area is sized around the Tank 500's curb weight, center of gravity, and off-road use case — enough clamping force for hard stops, but calibrated so low-speed maneuvering over gravel and loose surfaces stays predictable rather than grabby.
- The 345mm high-carbon rotor carries more thermal mass than the stock disc, so it resists fade through long descents, repeated braking, and towing — where heat buildup is what actually causes pedal fade.
- The integrated one-piece bracket keeps the caliper rigid under repeated washboard impact and hard braking, so pedal feel stays consistent instead of going soft or vague on rough trails.
- Direct-mount fitment uses the Tank 500's existing bolt pattern — no flange, no cutting or drilling, and it clears the factory 18-19 inch wheels without spacers.
- The off-road-specific internal brake line layout is routed to hold up to water fording, mud, and constant vibration without the pedal feel going inconsistent.
