Front End Noise While Braking
I have a 97 GTP with 150 K miles. It been running good but last week I started hearing some noise from the front end when I brake. Here is what happens:
I can hear some faint noise like the tire is out of balance when crusing at 65-70 miles. I did get the tires rotated and balanced so that is ruled out. When i brake at 70 MPH, everythng is fine until i come to around 50 MPH. I start hearing noise(pulsating noise which gets real loud before dying down) from the front end (probably front right) and it dies when i reach around 30 MPH. There is no vibration in the steering wheel. I changed all four brakes (new rotors and pads) about 3 months ago and since there is no vibration when i slightly press the brake pedal at 70 MPH, warped rotors can be ruled out too. Any feed back on the problem will be appreciated. Thanks in advance.

Re: Front End Noise While Braking
I have kind of a grinding/catching noise when I brake. It's not paticularly loud, but I dunno if that's what you're talking about. I've narrowed it down to a problem with an ABS sensor, which I'm going to avoid replacing until I have the money. Dunno if that applies, but that's my brake noise

Make sure the caliper bolts and the caliper bracket to spindle bolts are still tight. It could also be a tie rod end, strut mount or control arm bushing.

Hi...newbie here....
My '98 Grand Prix GT just started doing the same thing @ 123,000 miles. When you figure out what it is, please let me know! Nice forums, by the way!

Re: Front End Noise While Braking
Guys, We finally found the problem. I took it to a mechanic and he told me that the brake rotors were warped. At first I didnt agree since I had new rotors few months back but when his explanation convinced me. Faced the rotors and it stops smoothly now. His explanation was:
Our cars have floating calipers and they float on a pin.While installing new rotors/ pads, if you dont grease those pins with high temp grease, the calipers might not slide smoothly. So when u take ur foot off the brake pedal, one of the pads may stay in contact with the pad. As a result, the rotors heat up and they get warped.
