Stop Lamps
The brake pedal position sensor is used to sense the action of the driver application of the brake pedal. The brake pedal position sensor provides an analog voltage signal that will increase as the brake pedal is applied. The body control module (BCM) provides a low reference signal and a 5-volt reference voltage to the brake pedal position sensor. When the variable signal reaches a voltage threshold indicating the brakes have been applied, the BCM will apply battery positive voltage to the stop lamps, center high mounted stop lamp (CHMSL), transmission control module (TCM), and engine control module (ECM). Ground for the right rear stop lamp and CHMSL is applied at G402. Ground for the left rear stop lamp is applied at G400. The stop lamps on this vehicle will not illuminate unless the ignition is in the accessory, run, or crank positions. When the ignition is in the OFF position the stop lamps will not illuminate when the brake pedal is applied.
Do you know what DTC'S - diagnostic trouble codes are ?
DTC B3903 02: Stop Lamp Relay Circuit Short to Ground
DTC B3903 05: Stop Lamp Relay Circuit Open or Short to Voltage
DTC C0277 06: Brake Pedal Position Sensor Circuit Short to Ground or Open
DTC C0277 07 : Brake Pedal Position Sensor Circuit Voltage Above Threshold
DTC C0277 09 : Brake Pedal Position Sensor Circuit Rate of Change Above Threshold
DTC C0278 00: Brake Pedal Position Sensor Not Calibrated
DTC C0870 03 : Device Voltage Reference Output 1 Circuit Voltage Below Threshold
DTC C0870 07 : Device Voltage Reference Output 1 Circuit Voltage Above Threshold
Your best bet mite be to take it to a qulaified repair shop .
SOURCE: turn signal light comes on when braking
Probably a bad grounding, causing the current to go other ways than intended i.e through other lamps. Check for corroded lamp sockets or bad ground connections in the tail light assembly, also check the lamps so they are ok.
Good luck!

2007 PONTIAC G6 CONVERT. BRAKE LIGHTS STAY ON WHILE DRIVING AND GO OFF WHEN PUT BRAKES ON, AND YOU CRUISE CONTROL WILL NOT WORK WHILE BRAKE LIGHTS ARE ON.
SOURCE: Brake lights stick while driving but turn off when pressing brake
CHECK YOUR BRAKE LIGHT SWITCH THAT IS ON YOUR BRAKE PEDAL UNDER THE DASH

I don't know if your Mazda is all electrically ran, but it sounds like it. It may be as simple as a fuse, but mine ended up being the entire fuse block had to be replaced. Also there may just be a loose connection, especially after an accident.
SOURCE: press brake pedal hard and release the n/s/f and
This is a system on subarus to stop you rolling back when on a hill with the clutch depressed . The brakes should unlock as you release the clutch. There is a cable attached to the clutch fork in the engine bay. This goes to a brake actuator on the left hand side. If it isnt working corectly check the cable for wear or fraying. It may need adjusting by a mechanic.
