Toyota Land Cruiser Prado (LC250) Big Brake Kit Upgrade / TTSPORT Direct-Mount OR6
A Toyota Land Cruiser Prado LC250 built for long-distance overlanding, heavy camping loads, and rough terrain asks a lot more of its brakes than a daily commuter ever will. TTSPORT built a vehicle-specific off-road brake package for the LC250 around this exact use case: the OR6 six-piston caliper paired with a 345mm rotor, aimed at stronger, more consistent stopping power under sustained heavy-duty braking.
The build stays behind the factory 18-inch wheel, uses the vehicle's stock mounting geometry, and adds real hardware where it matters: a bigger rotor and a stiffer, higher-piston-count caliper up front.

Why It Works
The bracket is built off the LC250's own chassis data, so it lines up with the stock mounting holes with no cutting, no drilling, and no spacer needed. It also clears the factory 18-inch wheel, which matters for owners who want to run the same wheel and tire setup off-road that they run on the highway.
- Six-piston layout with 79 cm² of combined piston area adds clamping force for heavier loaded weight — camping gear, roof platforms, auxiliary fuel, or a trailer.
- The larger 345mm one-piece rotor increases thermal mass, which helps the system shed heat during long, repeated braking on grades and descents.
- Forged two-piece aluminum caliper construction resists flex under load, which keeps pedal feel more direct compared to a caliper that deflects under high clamping pressure.
Off-road driving also throws washboard, rock crawling sections, water crossings, and mud at a brake system in ways that pavement never does. TTSPORT tuned the internal hydraulic layout for this environment so it can hold steady fluid pressure through vibration, heat, and moisture exposure, which helps limit fade and a soft, spongy pedal on long mountain descents or high-altitude routes.
