#2 of 17 Brake problem with 98 Grand Marquis
Oct 25, 2006 (5:58 pm)
Hi! I just joined this site because I am having trouble with my beloved GM. The garage is not able to reproduce my problem and don't know what is wrong, so I am hoping that somebody here may know.
After my last service, I was happily driving around, until I came to a traffic light. All of a sudden my car stopped, as if it had bumped into something. The wheels were completely locked up, and I had to put it in reverse to get it moving again.
I brought the car back to the garage, and they cleaned the brakes, but could not find any problems, or reproduce this behavior. So I took the car back.
For a week and half, the car was fine. Then, this weekend, something similar happened. This time the car didn't fully lock up, but there was a loud bang, and it felt like some brakes were being engaged. I could drive on, but it felt like there was some friction. This happened about 7 times this weekend.
Back to the service station --- and again they cannot reproduce it. So I am hoping anyone here has any idea what this is, or maybe someone even had the same problem. Any input would be greatly appreciated.
To reiterate: it happens when I'm driving quite slowly (driving towards a stop sign --- I live in a small town where quite a few people still stop for these --- or a traffic light). Suddenly I hear a loud bang, and it feels like some kind of brakes are engaged.
Thanks in advance for your help!

Can you tell if the front or rear brakes are causing the problem? Sounds almost like one of the brake calipers is binding or sticking. How many miles on your car?

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...

#8 of 17 possible brake noise
Jul 23, 2007 (9:02 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.
