I am experiencing vibration through the brake pedal when the car is at a complete stop. The vibration is noticably stronger when the climate control is ON. Any suggestions on what needs attention/replacement? This is particularly annoying on the foot on longer drives through the city with alot of stop and go. I'm a 98 autotragic. Thx

When I notice a vibration, it was on and off....like one sec it would virbrate then stop....5 sec later starts again. When I was looking at my brakes, I notice the ABS sensor was bent and touching the rotor, which was the reason why I got the ABS - short in rear left sensor code. I replaced the sensor and no more vibration. My theory is that the short was messing with the ABS, which caused the brake pedal vibration
