Unhappy Brake Caliper Sticking



Hey all, Hope everyone's been doing well.

Yesterday I was driving and my truck was turning hard to the right. So I figured something was wrong. I got out and looked. My brake caliper was sticking, it was smoking.

We took the wheel off and cooled the caliper. Put some lubrication in there and used a flathead to make some space haha. It got me home and it's working fine now... but do I need to replace it now or what?

Take off caliper and caliper bracket. Check the clips/slides and make sure they are clean of rust and corrosion. Scrape those surfaces as flat as you can or use a wire wheel or w fiberglass cookie to clean everything up. Regrease where pad slides on. Push the piston all the way in to make sure its moving properly. C clamp big enough and an old pad will do this. This is the most important. Check the spiders for the caliper! Pull the pins out of the rubber boot and clean them off with a rag. Grease them with CALIPER grease only and reinstall. Do not goin it just a nice even layer over everything and if everything is sliding as it should, your pads aren't rusted in place and have room to move as they should and your piston isn't frozen you should be good to keep driving. Happy travels.

I've replaced my front pass side caliper twice and driver side once...no matter how many times I take them apart and clean/lube them.

I had the same problem a while back on the driver side. One problem is that now that this has occured you will have uneven where on your pads especially if it happens again without fixing the problem. unfortunately, everything comes in pairs. So I say do right once with higher quality aftermarket parts. You will have to do some research to find what is best for you though. Best of luck!

If it's an OEM caliper on the truck now, it probably has a ceramic piston.

Those pistons have a tendency to develop hairline cracks in them and seize. If it's gotten hot to the point of smoking, but exercising the caliper freed it up, it's take it as a warning and just replace the damned thing.

Be careful when buying a caliper, have your VIN handy.

That happened to my f150 every now and then. I just turn the wheel and give it a few good smacks with a hammer, frees right up.

Haha lilbit where are you located? If your in my bring her on down and ill take care of it for you.

And the hammer idea sounds a little dangerous. Also I wouldnt replace a caliper unless I had to. As long as the piston moves freely you should be ok. "just replacing it" is pricey. Also fords oem parts are all you should be using unless you have a purpose for changing to aftermarket. Fords quality far surpasses most after market brands. Our pads I believe are mad in Italy I found out today. Not sure if its all pads but at least on the escapes they are.

It's not "just replace it", it's replace it due to the symptoms that they could wind up chasing for months. A sticking caliper can also develop enough persistent heat to damage other pieces of the hub assembly. The OEM calipers are NOT superior to aftermarket rebuilds in this case, as the aftermarket calipers have stainless pucks to replace Ford's OEM ceramic.
