Check switch isn't depressed at pedal. If power going in & coming out, when not depressed, replace switch.

    Just had same issue of brake lights staying on after replacing brake boostert o solve a sucking noise from the brake pedal area.
    Asked the supplier and was told the brake light switch needed to be reset, but was not clear how.
    I pulled the switch out after a bit of time with no sucess, i just gave the plunger a hard pull with pliers. It came out, initially I thought I had broken it.
    Then I just reinserted the plunger part way, reinserted the switch, test drive, problem solved, all working as it should.

Change battery and alternator but 08 Silverado battery goes dead after turning off

You have a current drain in your system. Using an ammeter identify the amount of drain. then pull fuses one by one until the drain disappears. Now you have the circuit that is responsible for draining your battery. You have to check all of the peripherals on that line.

Batterie and brake light stays on changed new batterie new alternator car ran fine the next day the car would not crank

There is obviously have a drain on the battery. You have a faulty break light pedal switch causing the lights to stay on, or your turn signal switch is bad. your brake lights run through, the turn signal switch too. That could also cause the problem.

Brake and Parking lights won't turn off, even in "OFF" position - Drains battery

Get under the dash ad look at your brake pedal lever. You will see a stop light switch that screww into a bracket with a 'button' sticking out of it. if pulling up on the brake pedal (even slightly) solves your problem, then the switch needs adjusting closer to the brake lever. If adjusting does not stop problem then replacement of brake light switch may be required.
