Certification is req'd because LR didn't specify the smaller brakes as an option with the 3.0 engine on their ADR approval application. The fact that LR listed the 2.7 engine as the standard engine for the SE for ADR approval and that the handbook states that the kerb weight for the SE wont include possible options such as factory-fitted heavy duty brakes doesn't make it legal. My insurer only requires that the vehicle be roadworthy.
