It can be a high-pitched screech, a thud or a metal-on-metal grinding noise. These sounds can mean that your caliper is stuck, that it has come loose or that it's having some other problem. ... A seized brake caliper or caliper sliders can cause the vehicle to pull to one side or the other while braking.

How do you know if your brake caliper has seized?

If the piston is stuck within the caliper, or the pad is stuck, the car can feel down on power (as if the parking brake is on). You may also notice the car pulling to one side with the steering wheel pointed straight, when cruising and not applying the brake. As you drive, the seized brake may also get hot – very hot.

Can a caliper make noise?

Squealing or metallic rubbing noise.

If a brake caliper is sticking or freezing up, noises may be heard from the area of the damaged part. Unlike the noises related to worn brake pads (which occur when the brake pedal is pressed), this symptom is likely to be heard when the brakes are not being used.
