Well I stored my mustang all winter considering I live in god awful Connecticut and all.. So I took the stang back out for the first time this year.. I've been drving it for about a week now and i have a *creeeeeeking* noise coming from the driver's side front caliper when the brake pedal is depressed about 1/2 to 3/4 and then when released. It occurs whether the rotor is moving or not and when i put my hand on the caliper as my dad pumped the brakes it felt like the back of the caliper (piston housing/stiff metal brake fluid line) was the part most intensly creeking (vibrating). I figured it just dried out so i greased the slides with caliper grease and all the spring contacts along with some antisqueel on the backing of my pads... no luck.. Any ideas?? maybe flushing the brake system.. Could have some moisture in there causing the caliper to squeek. it's pretty loud too btw you can easily hear it from 20 feet over the flow's
