Did you stop by just slamming into whatever was in front of you?

True about what the poster asked above. You wear them out much quicker if you're constantly starting and then slamming on the brakes. Plus now days they are making some more durable. And yes they can be worn and for some reason may not hear the noise, which you should be able to. But you can always look at your rotors to check for any grooves from old pads. You want the rotors to be smooth all the way around.

Fixing a stuck caliper may be as simple as regreasing the caliper pins, using a good, high temperature grease.
There is a better chance the pin has corrosion which is causing the sticking, in which case the pins need to be replaced at a minimum, probably the whole caliper.

If the caliper was sticking then it is likely the brake pads need to be replaced because the stuck calipers caused the pads to stay in contact with the disk resulting in the brake pads overheating.

The time my caliper got stuck, the brakes became so hot there was smoke coming from the rear wheel well and I was concerned something would catch fire. Did I mention the gas tank is real close to the rear wheel.... Serious pucker factor that day.

No, but I've driven the same with all my vehicles and have noticed the pads last much longer now.

Brake calipers are trashy.

Check the slide pins. And grease them before changing the caliper.

I am not trying to be condescending, but if you don't know the answer to this, then you probably shouldn't be working on your own brakes. time for a brake job.

Spray WD-40 on everything within a foot of it. Speed up to qualifying time, then test for stickiness.
this is fine short term. Wouldn't have to remove the tire, but wd-40 won't hold up to the heat for long. Use proper lubrication or replace caliper.

Do all pads make noise when they need to be replaced or just certain vehicles?
Yeah all pads have tabs/clips attached so that when the pad wears down to a certain point the rotor rubs that clips which is metal on metal.

I was just funning with him a little bit. He has gotten the correct answer many times in this thread so he should be good to go.

For those who are wondering, the correct answer for him is to have somebody else do a brake job. (Or learn how on Youtube.) He is unaware of the small piece that rubs the rotors when the pads get too thin.

I had a car with a caliper that would stick but not constantly. I replaced the brakes, the rotors, and even the caliper but it still kept getting stuck. Finally figured out it was the rubber brake hose. Found out it was designed so that when the hose failed it collapsed in on itself and wouldn't let the brake fluid flow back out of the caliper when you released the brakes. That way you didn't lose your stopping power when the hose wore out. Not saying that's the issue here, but I didn't see anyone else mention this so I wanted to throw it out there.

If the caliper was truly stuck or sticking, you could lift the wheels off the ground and turn each one by hand and find the one that is sticking.

I replaced my brake pads a few months ago and greased the caliper pins but I had one fricking lock up while I was driving so I had to go buy new calipers and replace them on the side of the road.

Apparently the piston can wear a groove in the cylinder and get stuck. Better to replace it if you think it's sticking.
