Customer Question

I have a 99 mystique with 112k miles. I had the brake pads, r front caliper and rotors, l front rotor, rear brake drum, rear shoes replaced yesterday. On my first five away from the repair place, the brake pedal vibrated when pushed. On my return to the mechanic, I thought I was going to hit the car in front of me from my car not stopping. The mechanics could smell it and said something got too hot. They did more replacing. My car now seems to stop better, but I still have brake pedal vibration, which I never had. Now I have to bring the car back and I'm very annoyed. What could be causing the vibration?

Generally a vibration when braking is caused by either rotors that have too much runout or variation, or rear drums that aren't round, more like being oblong. It could also have dirt or rust behicne the front rotos causing them to run untrue having too much runout.
