The brake light switch should not affect the operation of your brakes.



However, check to make sure there are no wires hanging down and interfering with your brake pedal. There could be more resistance on the brake pedal if something gets wedged.



Otherwise, start going over your brake system.
the brake light switch would have nothing to do with the problem your having, you have some other problem.
It can happen. Some cars automatically turn off overdrive when you hit the brakes so the engine will help slow the car. If the old switch was on all the time, overdrive would never engage and you'd have better acceleration because you'd always be in third gear. Fix the switch and overdrive works again, reducing response quite a bit on the highway.
