after reading about the groaning brakes on the liberty jeep. hope maybe someone can help me. do they make the caliper slippers for a 97 mercury cougar? i have had this problem since it was new. i had the ford dealership do a brake job about 9000 miles ago and still does it. the ford dealership said it was a humidity problem. i don’t think they know either. my wife has about drove me nuts with her complain- ing about the noise. any ideas out there\> daryl ---

My wife has just complained about the same noise as she left the driveway yesterday. I told her that after two or three brake applications the noise will disappear. A half hour later at our daughters house she phones, the noise went away, what was it? Overnight rust build-up on the rotors. Common problem ever since discs brakes showed up. ---

i thought the same thing about the overnight rust on the rotors. i have removed the wheels and cleaned the rotors. did not make any difference. i have driven 100 miles and more at times, riding the brakes hard stopping when i could, it helped some but still it would still groan. i have a hearing problem, but when i can hear it, it is bad. anyone else got any ideas? thanks daryl ---

Hmmmmm, sometimes slightly worn wheel bearings will emit a groaning sound until they start grinding and squeaking.
