Why dose my break lights come on when barely press on the pedal but when I continue to press harder on pedal to slow down/stop the car the breaks lights go off.... its on my 2000 mustang
How long dose it take to get a answer on here....???
You might have a bad brake pedal position switch. PS: it usually takes about 46 minutes to get an answer around here.
Any other possibilities
Do BOTH brake lights go on/off at the same time? Is there any flicker to them? Under/near the brake pedal is the BPP switch/sensor. Have someone stand behind your car to watch the brake lights. Reach under the pedal and play with the switch. If it feels loose or sloppy, or doesn't keep the brake lights on when pressed, it's a bad switch. It's a cheap part to replace. You already know the problem is not with any fuses or bulbs.
