It means it is time to have your brakes checked.
squeaky sounds that go away when you push the breaks are most probably the indicators on your brake pads that squeak to let you know that they are getting worn out and need to be replaced soon also dirty brakes will chirp while driving, a thorough cleaning and lube of the proper parts usually cures this There are typically metal tabs on your brake pads that are meant to squeak when your pads start getting low. It is possible that is the cause of your squeak, check your pads, or have a mechanic check, as this is a good possibility, however not a definite.
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!
sound to me like you have air in your brake lines try bleeding your brakes
Do you mean when you push the pedal " hard " you hear noise..........if so could be the ABS..........if not, then please have your brakes checked for safety.
Warped rotors
Compared to todays modern brake systems they will feel hard. Also depends on if they are power brakes or not. Some cars of that era did not have power brakes and they were very hard to push.
slowly push it along then pull the brakes, if it stops, THE BRAKES WORK!!! if it keeps going, THE BRAKES DON'T WORK!!! IT'S ROCKET SCIENCE!!!
Disc brake pads push in. they pinch the rotor
On motorcycle, it depends upon brakes like pushing on front brake mean inviting huge disaster for yourself; while back brake is quite safe because it will automatically lock the front tire as well.
Rotor out of round or pads are grabbing for some reason most likely, possible bad wheel bearing as well. .
simple hydrolics. You have a canistor (master cylinder) which holds the fluid. When you push on the pedal, The cylinder opens and pushes fluid to the brakes which push against a disc to slow the momentum
If your brakes are squeaking, that means the pads are wearing thin. When you hit the brake pedal, the pads push against the rotor to create friction and slow down the vehicle. Over time these pads wear away, and when they get thin enough they make a squealing noise. This noise notifies you that you need to have new brakes installed as soon as possible. If you keep driving without replacing them, the pads will eventually wear down completely and then every time you hit the brake pedal metal will scrape against your rotors. This can be very damaging and dangerous, so when the brakes start to squeal have them looked at right away.
