rafamr,
For "BRAKE LINING", like i said, check the brake pad sensors, there are only 2 sensors, one is at front left wheel, and another at rear right wheel. Check whether are they properly connected, and check the pad sensors condition, did you also change front brake sensor recently?
For "1 BRAKE LIGHT", like I suggested, try to unplug the wire & plug in back to the brake light switch, if that does not help, try to change the switch.
Function of the brake light switch is when you press brake pedal, it will triggered this switch, and "ON" signal will be sent your brake lights. The signal will also send to Check Control Module & Transmission Control Module.
Boleh faham ke?
