Any help in diagnosing this would be greatly appreciated. I am not a mechanic. But I like to do the easy things myself.

Ok, hereís my problem.

When driving down the road I get a knocking noise coming from I think the front wheels. This noise stops when I depress the brake pedal. I also think that it goes away when going around a turn, but not sure on that one yet.

I've taken all the wheels off and spun them as fast as I could by hand and could not recreate the noise. I did that same with the rear wheels, put in neutral, jacked the rear end up and spun wheels and yet no noise.

But I'll be damned, as soon as I go back out on the road, there it is. Its driving me crazy.

Iím ok with taking it to a garage, but if its an easy fix Iíd rather do it myself

Thanks
Scott

Could be the pads are loose in the caliper.

Have someone press pedal, and clinch the tabs over with big channel locks.

Also check the caliper mounting bolts for proper torque.

Have you checked your ball joints? With the brakes applied it could be loading them in such a way that they don't knock.

I've taken the wheels off and the pads are a little loose, is this normal? or should they be tight?

thanks

If front drums, then the self adjusting spreader is too far open. If front disc, then possible warped rotor making the pad flop back and forth.
On either setup, if someone tightened the spindle/hub nut too tight, then with car weigh the small outer bearing is locking up. When the small bearing locks up, then the bearing race will start to turn instead. If that is the case then you can take the outer bearing out and the race will move back and forth proving the slop.

also check the tie rods. They will make noise when "unloaded" and go away when under brakeing or cornering.
