You failed to set brake light switch propper...
The threaded shaft withthe nuts on it, you want air gap about the thickness of credit card or slight less to the pad on the pedal... not between plunger and pedal,,, the pedal sitting holds plunger into the switch to open the circuit (lights off).
You have the theaded shaft on the switch too tight to the pedal, holding the pedal slightly forward enough so as to not allow fluid to return when pedal released.

Step 3 below is the part you need to check on.
BRAKE PEDAL HEIGHT ADJUSTMENT
Remove the carpet and measure the brake pedal height. If the height is over the standard value, adjust it as the following procedures.
157.1(+5,0) mm [6.19 (+0.2,0) in.]
1. Disconnect the stop lamp switch connector, loosen the stop lamp switch lock nut, and back off the stop switch until it doesn’t reach the brake pedal arm.
2. Loosen the push rod lock nut, and screw the push rod in or out with pliers until the standard pedal height from the floor is reached.
3. Turn the stop lamp switch until clearance between the stop lamp switch outer case and stopper becomes 0.5~1.0mm.
Tighten the lock nut firmly.
Brake pedal stroke should be 125.6mm (4.95 in.) or more. If the brake pedal stroke is not 125.6mm or more, readust the brake pedal height and stop lamp switch clearance.
4. Connect the stop lamp switch connector.
5. Make sure that the stop lamps go off when the brake pedal is released.
6. With the engine off, depress the pedal 2~3 time to get rid of pressure, and then inspect the play on the pedal by pushing it by hand.
3 ~ 8 mm (0.11 ~0.31 in.)

Yes, if the brake light switch is not installed and adjusted properly it will cause the brake pedal to be depressed slightly as if your foot were on the pedal. Did you check the adjustment of the switch?
