Default Squealing in reverse

Sometimes when I reverse out of my garage I hear this shrill squealing noise, especially when I turn in reverse out of my driveway. Whenever it's happened I haven't had my foot on the brake at all and by the time I stop to put it into first and drive away the sound stops. So it's really only an occasional high-pitched whine when I reverse for a couple seconds out of a parking spot or something, although I'm a little unsure what part of the car it's coming from... I searched in other threads and other people who have had a similar problem have mentioned everything from fresh rust being ground off of the brakes, to some under-lubricated part. Anyone ever here of this? Thanks

Are you sure you aren't just hearing the typical reverse whine? Post a video. As you increase speed in reverse, the pitch increases in frequency due to straight cut gears.

That is definitely your straight cut reverse gear.

No worries.

Is this your first manual car?

Here is a vid of my Legacy in reverse, squealing away:

If it sounds like that, it is just your reverse, don't worry about it.

the noise is definitely a much higher pitched whine or squeaking. i'll try to get a video, although it doesn't happen every time i drive the car, so we'll see if i can catch it

Does it sound like a slipping belt? I had that problem when my ac belt needed to be replaced. Check to see if you can turn it more then a quarter turn. If you can then you can tighten it in the meantime but you should probably replace it.

How many miles are on your car? Have you had the brakes checked lately? Sometimes the wear indicator on the brake pads can do what you are describing, make more noise in one direction than the other, and depending on if they are warm or not, sometimes not make noise at all.

The wear indicator is just a piece of metal that touches the rotor when the pads are low. It's supposed to emit a high pitched squeal all the time, but does not always work perfectly.

i have 79000 on the car with pretty fresh rotors and pads, i'm really starting to think it sounds like a slipping belt of some kind, but i don't know enough about engines to be sure since it's really only triggered by me reversing outta the garage, usually cold in the morning

Have you tried twisting the belt? If your unsure, go to a parts place like AutoZone and ask then to do it. If it is bad then search for a guide on how to replace it. I'd link you to one but I'm on my phone. The replacement is really easy. I'm still pretty green myself and it was no problem for me.

I'm still sticking with the brakes since it only does it in one direction, and is temperature dependent. If it were your belt, it would do it all the time, regardless of which direction you were driving. It may not be the wear indicators, but could be the pads themselves. What kind of pads did you get?

If it was done recently by a shop, I would take it back and say there is a noise, and that you want to make sure it's not their brake job that did it. If you did them yourself, there are a few tricks that you can do to stop the noise, assuming it is the pads. (Pads can vibrate at high frequency, which can cause the noise. Brakes setup for race tend to be VERY noisy when they are cold, and even street pads can make some noise when cold)

Does the noise go away when you press the brake pedal?

A video or audio recording might help.

Regardless both are important things to be aware of. Check both.

I've started to get a squeal also when turning in either direction, reverse or forward(mostly in the early mornings backing out and at or close to full steering lock) and I know it's my belts.

Slug, if you rev the engine does it change the sound at all?
