Driver's Side Rear Brake Squeeking on My 2002 V6 Mustang

My driver's side rear brake is making a horible screeching sound when i let off the brakes and it eases forward under its own power, however when i give it gas as soon as i let off the brakes it doesn't make a noise at all. I do believe this problem is linked to the fact it looks like my caliper is tilted some like this / if you are standing at the back of the car, i say this because the pad doesn't touch the rotor all the way maybe missing about .5-.75 inches of contact, picture is attached below, any ideas on what could be causeing these 2 problems?

first things first

First thing i'd be doin is taking that there wheel off and checking to see if my calliper sliders are working. clean em up and lube em up with silicon based grease. Check your bracketS holding the pads in place on the calliper bracket some one might have installed incorrectly. Also clean and lube upon installation for easy ramoval in the future.

Most importantly check your brake pistons. make sure they're working evenly.

the floating pins work (in one direction anyways lol, back and forth but could they get angled?) i checked when i put on the new brakes 2 weeks ago, the bracket set flush when i put it on, i took my time so i wouldnt cause any problems i'll be sure to get some of that silicone lube next time i can and try that, when i was under the car a couple days ago i noticed that it looked like the back side where the pistion pushes the pad against the rotor was making full contact, i know this may seem like a stupid question but is it possible that the caliper could have been bent before? (as this has happened before, actually since i've had the car 2 years ago, but never as loud, i'm guessing because the pads/rotors are still fresh they are making it louder)

Sure

No question is stupid man. Common now.... :yelpleased:

Sure something could be bent. Anything is possible. Maybe it's a defective calliper or bracket that needs to be replaced. Triple check all bolts. Make sure they're tight and flush. One may be stripped in and sideways on either the calliper to the bracket or the bracket to the nuckle.

If you have the old brake pads take a look for even wear. Are they even or angled?

Something tells me your sliders/floaters aren't working right.

Yeah the old pad on the outside is angled a little not major by it's angled, so does that mean floaters?

for anyone who still may look at this thread, the noise/angled pad was caused by a little nib on the back off the pad that is used to line up the shim that goes on the back of it, grinded it down enough to get out of way and the noise disappered like magic
that little nib is why i had trouble getting caliper back on in the first place it barely bolted in, but now it just drops right in with no hassle, thanks for all the help!!
