Sounds like you need brakes. Have it looked at soon! Or maybe the fact its a Chevy that might be the problem
Most of the time it is caused by the disk (rotor) being warped for previous "locking up" the brakes. If you've ever slammed on the brakes that could be the reason why. Basically it's a rotor problem most of the time.
The road surface could be slippery, your brake pads could be worn, your tyres could be worn, your brakes could be faulty.
If the brakes on a Mazda 6 are squeaking, it could be indicative of a problem. The brake pads could be incorrectly set.
It could be air in the brake line, or the brakes getting too hot from too much friction by using the brakes on a steep hill or riding the brakes, or there could be a problem with the master cylinder.
That will depend on many factors including driving habits. The brakes could last 30,000 - 150,000 miles.
just keep driving, if your have not checked your brakes then i would get a professional or you could take off your tyre and look at the brakes. consider getting new ones if they are looking damaged
If the car vibrates when the brakes are applied, it could be a sign that the brakes or rotors need to be checked or replaced. When a problem like this occurs, it is best to get it checked out as soon as possible to avoid worsening the problem.
It could bend valves.
If there are disc brake, it could be frozen caliper slides or a frozen caliper piston. If they are drum brakes, it could be a frozen wheel cylinder.
Bring to a shop that has an ABS scanner to determine the problem
the problem is that the brakes don't work.
