Hey guys, haven't been on the forum much lately since I just moved cross country, hope everyone is good! I'm looking to get some input on a slight brake issue, since I am still a rookie to high performance cars and maintenance.
As best I can recall, since I've had the car (picked her up last June w/ 6k miles, now at 21k) the brakes typically chirp a bit after extended sessions of hard driving and hard braking. The chirp only happened when I was not on the brake, seemed to happen about once per wheel revolution, but could be temporarily quieted by applying some brake pressure. The chirp would stop for a couple seconds until the car was jostled a bit by the road and then it would come back. Typically the sound goes away by the time I got home from the driving session, with the exception of some really hard sessions. The last few times I've tracked the car and checked closely I had plenty of brake pad left, no visible rotor wear, and I have no vibration under braking. The chirping has definitely gotten worse, and while I initially thought it was the rear brakes chirping from uneven wear due to ESC/ABS I now believe the front brakes are the main cause of the noise. Since I've been busy with the move I haven't had a chance to take the wheels or brakes off to give it a close inspection, so I was hoping someone might be able to point me in the direction of the cause/solution in the meantime. One of my friends back on the east coast with a '13/14 GT had a similar issue, but he had Hawk pads which were just loud all the time so he never really looked into it. Since the chirping has gotten louder and more consistent in addition to lasting longer, I figured it was time for me to figure out the issue. I don't think it's a rotor issue, could it be a loose/misaligned pad or caliper issue, or just time for new pads?
Has anyone had this experience with their Boss/Mustang, or does anyone know what the cause might be?
Any insight would be greatly appreciated! Thanks!
