Help with loud truck break caliper squeal

So today, I took my wheels and break calipers off and painted them. I then reassembled them and took the truck out for a drive. There is a very loud squeal coming from one of the tires/calipers. Any one know what I could have done wrong?

Gotten break pad dirty?

Something not aligned right?

?

First, year, make and model would be helpful.

Second, did you replace the anti squeal compound on the back of the pads? - if it uses that. What did you paint? “Calipers” isn’t enough information.

More detail would be very helpful.

+1 for CapriRacer. We need a lot more info to ascertain why your brakes are squealing.

I vote that posters that use “break” instead of “brake” be banished from the forum. Is it REALLY that difficult to use the correct word?

I second the motion.
