Can brakes squeal when not applied?

Can Brakes Squeal When They're Not Applied? Your brakes can squeal when they are not applied. Usually, this is because the brake-pad-wear indicator is touching the rotor. If the wear indicator is touching the rotor, sometimes the noise disappears when you apply the brakes and returns when your foot comes off the pedal.

Can bad rotors cause squeaking?

Noises When the Vehicle Brakes

Warped rotors can cause a squeaking noise when the brakes are applied. They can also make a scraping or grinding sound when they're warped and worn down. The squealing noise, however, can also be made by brake pads that are worn out.

What happens if you don't use brake grease?

This lack of lubrication causes a few things to happen. First, because the brakes don't contact the rotor properly, your brake pads can wear unevenly. Second, the slide pins may stick, causing the brake pad to continually contact the rotor, resulting in a buildup of heat, which wears your brake pads down faster.

Can you put brake grease on rotors?

Because it's so important, here's that reminder again: Don't ever put lubricant on the rotors or the insides of the pads where they contact the rotors. This will kill your brakes and cause you major problems on the road. Lubricate the few small screws on top and bottom of the caliper that hold it in place.
