I have a 2002 with 109k when brakes are applied in the front you hear a noise kinda like stepping on a bottle, its very faint and I doubt ill be able to get it in a video, but does anyone have same problem or know things it could be?
 
Stating the obvious... pads?
 
They may have glazed or you might have a stone jammed in there. I'd take them out and check them out. Doesn't take long to do.

I'll check this weekend, busy tommrow but its only when you press them, it doesn't do it when it rolls to me it seems like something with the pistons


How do you upload a video? I'm using my phone. The sound is very faint but can be heard
 
GL finding Cobra calipers. They're discontinued. Check brake fluid as well, or you may need to bleed them. I've heard that same sound on multiple customer cars (Work at Les Schwab, tire place for those that don't know) and all it was was it needed to be bled.
 
Idk, check the pads again, you can buy some stuff at your local autostore to apply to the back to prevent squeaking. Don't get the spray on crap it'll last a couple days at max.
 
So would you recommend upgrading to mach or cobra calipers, wouldn't hurt to change rotors out anyways

I all ready have cobra rear rotors because of my rear end swap
I'd take it apart if it was me, pull the calipers off (12mm head),check the pins for free movement, if they're moving good, get a small screwdriver and pull back the piston boots, look inside for any rust. Using a c-clamp or similar, try to depress the pistons, they should move freely.
A Cobra swap would be nice, conversion kits are easily available from LRS or American Muscle, or a ton of other places online. I prefer real Bullitt calipers myself, the ponies look sweet on the red calipers. Really though, if you're not hard on your brakes, the stockers are fine, just go down to the parts store and get some new/rebuilt stockers.
 
Try to have someone apply the brakes for you while you listen, walk around the car, listen in the engine bay ect. check to see if the ebrake engagement makes the same noise to solo out rear to front, also does it make the sound while cars off? or only while running? i would try and pinpoint the noise further so we can help.

I did pin point it, it is the Left front, wether car is off or on. I had the wheel off and you could feel it pulse, it is not the e brake or etc.. I think its what the one guy said, caliper is starting to seeze up, I greased the pins like he said and noise is still present

Sorry for mis-spellings
