Does it do it in neutral or only when its in gear with brakes clunking. How fast do you have to go? Faster the louder the clunk?

Hi. The car does not make any noise when I am driving or switching gears, it only clunks if I apply the brakes normally I can tap them very very lightly before the bad clunking sound. Thanks

Sound sto me like you should get the front end up and wheels off and look at the calipers. Try to move them forward and backward by hand they should not be moving in the rotation of the wheel. If they are loose check to maek sure the bolts are tight or not broken.

Sounds like the calipers are loose and are smashing into the knuckle when you brake.

Hi. My son-in-law took all the wheels off last night and put some kind of grease or something, and said that the all the brakes are good, checked everything took it for a little run, said it seems a little better did not clunck, but coming back he said there is a rattle, and still thinks something wrong, he said for me to drive it tommorrow-to-day and let him know a to-night, but what else do you think it might be, he said abs seems fine to, any suggetions would be greatly appreciated.I will let you know tommorrow night what it was like to drive. Thanks for all your help

Ah ok. Well since he checked the barkes make sure that he pryed on the caliper with some decent force to see. Also an alternative is to take the wheels off the vehicle. And jack up the front end of the car and put on the brakes after getting it some gas and see if you can duplicate the clunk if it does its in braking if not it could be a worn suspension component

Hi again. Welll I drove the car this moring and it seemed to be fine "so far" I so hope it is fixed now, but I will know better tonight when I drive it home, and I will ask him about these things which you said to check. I sure wish I could donate something but I just don't have any, but thankyou so much for helping me out.
