brakes clunk

[96tsiawd]

okay so ive searched [via search, and on talk and tuners] around and i cant find anyone with a similar problem. just recently i have been experiencing thump/clunk/grind noise when braking that is speed dependant [faster speed when braking faster thump/grind, vise versa]. this only happens after the car is moving for like >10 mins and it only happens when stopping under 20 mph. i am stumped. i have brembos [slotted/drilled], and i know they make noise when stopping but i have had them for a year and it never did it untill just like acouple weeks ago. i work at nissan so i put it up on the hoist and i checked to see if anything was binding [pads etc] and nothing. so just to make sure i started checking everything. with the wheel off i rotated the hub to see if there was any rubbing... nothing. but with the wheel on i grabbed my wheel and rocked it up and down to check for play and there was some. i am going to pick up a front hub/wheel bearing tonight but i honestly dont know if thats it because wheel bearings usually hum when they are going bad. any suggestions?

kyle-

btw i checked the cv boots, they are fine. also it is ONLY when stopping not turning.

Did you check to see if the pads were good on all 4 corners? Sounds like there is a pad that is totally worn or there is something lodged between a pad and rotor.

the pads were brand new axis metal masters [all 4 corners]. i checked the pads and they looked okay. though i wonder if i should put some more of that anti squeel grease behind the pads.

Check your ball joints and tie rods for play. They make a clunk if they are worn out, but mainly only when turning..

Also check your wheel bearing. Mine made clunking/grinding noises when one of them were worn out. Drove it like that for a few days and parts of it started coming off, haha.

First, adjust the post with a SHIFT key. I lost intrest after the first 3 lines.

Another thing that might be a way out possibility, but double check all the bolts for the calipers. We were out bannering one time and someone had this similar problem. It turned out it was one of his caliper bolts that had fallen out. It was on the front driver's side. It was the back bolt on the caliper that holds it to the bracket. When he'd hit the brakes, it would flip the caliper up and grind on the rims.

Maybe one of yours is loose. Otherwise I would check all of what was mentioned before as far as ball joints, tie rod ends and wheel bearings. I would lean closer to a lower ball joint.
