• Sign #1: Your brakes squeal. If you hear a high-pitched squealing noise, get your car brakes or truck brakes checked immediately. This is a built-in warning sign in your rotors that lets you know it's time to get them replaced.Â
• Sign #2: You hear a grinding noise. This is a sign that your rotors are getting damaged every time you use your brakes. Any more damage and you'll have a serious problem on your hands. Get them checked out ASAP to avoid that at all costs.Â
• Sign #3: Your brake pedal feels funny. This is a dangerous sign that means you need to pull over and check your brake fluid immediately. If your brake pedal goes immediately to the floor and has no pressure or if the brake pedal won't go down, this is a sign that there's a problem with your brake fluid and your brakes may not be working very soon.
