These wires are normally for the Brake Pad Wear Sensors which tell the ECU ( or Brain !) that the brake pads are worn low and need replacing. I would say VERY important !!!!
THERE IS A SENSOR ON THE FRONT AND REAR BRAKE PADS ITS TIME TO HAVE YOUR BRAKES SERVICED
Look for a square push button on the centre console in front of the brake lever.
i need knows wtah size is rear and front brake discs.
By replacing the front pads . they will reset automatically when the sensor sees the pads are ok.
