recently installed all new brakes
reset brake service light on 2007 Land Rover LR3
I wonder if one of the electrical brake wear sensors has worn through or has failed? Not sure if they need to see continuity or open circuit to keep the brake wear/warning light off , but closely inspect the sensors and brake fluid level. The sensor harness connectors are behind the wheel arches may be easier to do your tests there than taking of the wheels again.
