clunk when actuating brakes

2004 F 250, when putting on the brakes I hear and feel a clunk sound, it is really making me crazy. I am checking that all nuts and bolts are tight but this one realy has me puzzled. Any idea's. Recently put new pads on the rear, all seems correct. I also puit new shocks on this year???

Where is the sound coming from? I had a clunk in mine that was the sway bar bushings on the front end. I put new pushing in and it went away. Could also be balljoints if they are bad enough. Mine hasn't done it, but I had a friend with a F250 that had clunking. He brought it to Sears for the free front end check and they found his driver's side balljoints were shot. He replaced all four and clunking has been gone for many miles.

When mine did that, it was the caliper slide pins.

Had that clunk and it was a bad U joint in the rear drive shaft at the transmission output. Thought for sure it was brakes because it only made the sound when I hit the brakes, but it was actually the U-joint as it came to a stop that was clunking. If you pull the shaft off to check it also grease the slip joint at the yoke they can often cause a clunk. Use Ford's PTFE lube.

My clunking was caused by bad ball joints, the frustrating thing was that it would go away for a while then come back. Replaced my ball joints over a year ago and the clunking has not come back.
