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.

Problems to look for include caliper pins that are corroded, or ones that aren’t properly lubricated. Also, the pins could be stuck in the rotor or they won’t go in all the way after the pads have been replaced. The pins should be easy to take out with a screwdriver and a few light taps from a hammer.

These rails can become rusty or corroded, causing the caliper to bind instead of slide. Remove the rust and use the proper lubricant on the rail the pads ride on. Worn or loose slide pins or caliper slides result in caliper twist and lost brake performance. Always use the proper lubricant when working with brakes.

Non-lubricant-rated anti-seize should not be used where relative motion between parts is expected in service such as on caliper slider pins. Most anti-seize compounds are not lubricants, which is a desirable property in many applications.

One way to keep your brake calipers from sticking is to give them a good spray with brake cleaner. There are times when road dirt, brake dust, and other particles will get into the calipers causing them to “gum” up and stick. Brake cleaner will help penetrate into the calipers and loosen them up.

When you have caliper issues, the brakes may be very loud when you try to stop. 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.

Here are some symptoms to look for if you feel that one or more of your brakes has a stuck caliper: A major sign of a stuck caliper is if the vehicle pulls to one side when braking or while driving. Another sign of a stuck caliper is heat coming off the wheels after the vehicle has been driven.

Reasons why your calipers are sticking Worn/damaged caliper pistons. Just like the caliper bolts, the pistons have a rubber boot on the outside. Worn out brake pads. Brake pads come into contact with the rotors; hence, helping stop the vehicle. Dirty caliper slides. Handbrake/E-brake cables. Caliper bolts. Broken brake hose.
