Thanks for your response. I am not sure whether it is the front or the rear brakes --- if I had to venture I guess, I would say that I feels like the rear brakes. There are 92,000 miles on the car.

My intial guess would be that you have one or more worn out calipers and that they bind when you first apply the brakes and then abruptly clamp the disc (causing a bang and a sudden brake application). The caliper pins can rust and cause the calipers to bind. If you live up North having rusty calipers on a car with 92K miles is not an uncommon problem.
 
You can visually inspect the caliper pins by removing the wheel(s). Also, with the car jacked up, the front wheels should turn easily before you apply the brakes. You should then be able to apply the brakes (with the wheel off) and see the caliper evenly clamp down on the disc. If it binds and then "jumps" that is good indication you need to rebuild them. It's little more problematic to check the rears but it is do-able.
 
Here is a link to a site with some good brake info on our cars (front brakes in this case). The pictures might prove useful to see what you are looking for...

Hey how is everybody? I've got a 1999 MGM. I recently replaced front and rear pads and rotors. Now The abs traction control lights are going on and off. Sometimes just before coming to a stop the abs kicks in. Any help would be great. Thanks.

possible brake noise by geodak
Jul 23, 2007 (8:02 am)

I got a 96 grand marquis, 58k, and recently (last 2 months) a strange noise appeared, coming from the right side, possibly the rear right wheel. The noise sounds like a loud clicking and it shows up when I brake, but only just a moment before I come to a full stop. As soon as the car starts moving at low speed it might click a few more times, and as I accelerate it goes away. Is this related to the brakes, like brake pads being worn down, or is it something else? Help is appreciated

At 58k you have new tires and new tires pick up small rocks.
Use a screwdriver to pry out all the rocks between the treads and then test drive it.

Thanks, looked at the tires, no rocks, must be something else.

Have the same problem. It is the traction control energizing inappropriatly. Our GM has been doing this off and on for several years - no one, even FORD can fix it. It spent several days at the dealer, hooked up to a computer and they fixed it for about a year - by nthen it was off warentee.
 
It now has over 200,000 miles on it and we will keep it foreveras o ur spare.
 
We bought a 2003 GM (and kept this one also) but that had a button to turn on or off the traction control.
 
Guess what I did to stop the problem

Sounds like you have a problem with a wheel sensor or a toner ring. When you step on the brakes the computer looks at the sensor and toner rings at the wheels. The sensor could have a break in a wire or you could have a cracked toner ring giving your computer a false reading. That would tell your computer to engage the "Hold release apply cycle" which is the noise your hearing. I took my car to Meineke and they had it fixed in a day. The shop would need a good scanner and a good Tec. My does. So the first thing you need to do is get the car scanned by some one who knows how to interpret what he's reading.
