WD-40 but check your breaks before driving though
*********************
You do not say what part of your breaks are squeaking. WD-40 is fine for the moving parts on the break assemble, but not on the block which makes contact with the rim of the wheel. If it is the break block, then it is caused by friction between the block and the rim. The blocks may be worn, if so replace both blocks.
It could also be that your break assembly is loose. I am assuming this is for a bicycle. If a motor vehicle then it may be that dust has accumulated inside the breaking assembly. The rim may also need re boring to allow the break block to make a better contact.
Sometimes things such as sand will get into your brakes and cause the squeaking noise. In other instances, it might something mechanical beginning to fail. Regardless of the cause, if the noise continues you should see your mechanic!
Just spray it with Teflon or better yet silicone spray- mine was squeaking something terrible -- a few sprays at the joints and the stripping edge did the trick. Hope this helps

To help your outside door from squeaking you can purchase some WD-40 from your local hardware store, you do not need a large can something small will work, then spray the hinges really well.
1. replace brake pads.
If it is a Toyota, they do not know how to fix the squeaking brakes either. Even after replacing all the pads and machining the rotors and rear drums
rubbing from brakes or rubbing from frame
One word for you...Brakes.....
Usually it is the brakes that needs servicing.
If there is a squeaky noise coming from any of your wheels and from pressing on the brakes, then I am supposing that there is something wrong with your brakes. From my past experiences with squeaky noises coming from my wheels, I got it checked out by a mechanic and he said that my brakes were worn out to the point where I was going to lose brake control in the wheels that were squeaking. I would suggest you get your squeaky wheel and brakes checked out by a mechanic. You might have to only change the brakes if its not too serious. I wish you the best of luck!
Vibrations that come through the breaks squeaking can cause the irritating squeaking that we have come to know. The high frequency of the vibrations results in the high pitch squeaking. Alternatively, the squeaking can come from the disc that secures the brakes, when the vehicle is coming to a stop.
Your brakes are either wet from the rain that has gathered within your wheels, or you need new brakes!
