Where exactly are you putting each of the meter probes? Does it drop to zero volts when the pedal is released? The brake switches are doubled up for safety. It is unlikely they would both be bad. The problem is far more likely to be in the left taillight area or the engine compartment wiring junction box. There are 2 round 7 pin connectors in the box. One of these has all the wires for the rear lights. The brakelight wire is black/red stripe. Using a straight pin, push the pin into the wire. Push through the insulation and aim for the center where the metal is. Measure the voltage on the pin while someone pushes the brake pedal down hard. Put one probe on the pin and the other probe on bare metal ground in the engine compartment. On the same round connector are 2 wires that are grey with a stripe. These should have 12 volts when the headlight switch is on. Push the pin into one of these to verify your test setup. If you can't find 12 volts on one of these then you are doing something wrong and not finding 12 volts on the brake wire won't mean much.
