When the brake pedal is depressed, a switch is activated that sends a signal to the brake lights. Over time, this switch can become worn and may need to be reset. Resetting the brake pedal switch is a relatively simple process that can be done at home with a few tools.
First, locate the switch on the brake pedal. It will be located near where the pedal meets the firewall. There will be two wires connected to the switch - one for power and one for ground.
Next, disconnect both wires from the switch. Using a small screwdriver, depress the tab on the back of the switch and pull it out. Inspect theswitch for any damage or corrosion. If everything looks good, reinstallthe switch by reversing these steps.
Once you have reconnected both wires tothe switch, test it by depressingthe brake pedal. The brake lights should come on when you do this. If theydo not, then further diagnosis will be necessary to determine whythe signal is not being sent properly
