Here's the deal - when I press my brakes there is a kinda of clunking noise from what seems to be my front axle. I removed the front driver side wheel to take a look at the rotor and noticed this -



Is there supposed to be anything where those 2 holes are?

I think it's definately coming from the rotor because as I'm decelerating and am coming to a stop - the clunking slows down - as if it were something with the rotor.

Any and all help is appreciated! Thanks

EDIT - I found out there are supposed to be 2 screws there which is what I figured, however I don't think that is what's causing the somewhat clunking noise.

Anyone have any suggestions what I could be looking for as far as the clunking noise goes?

Just realized I posted the wrong picture.

A new one is up.

 

Yes you should have what is known as rotor screws in those two spots. Check with your local honda/acura dealer and they should be able to sell you some as they are stocking items. Nice n cheap too. Use a phillips head impact driver when installing.

Yes, rotor screws go there, but they really are not needed since the lugs also hold the rotor to the hub face. Does this clunking occurs once during braking or does it recur with the wheel rotation? Does it still occur if you apply the brakes firmly?

 

You dont have to have the screw there. They are to hold the rotor in place druing the assembly process. But one the wheel is bolted on the rotor can move and the screws become useless. Lots of cars dont have any screws holding them in place (like my 4runner)

I would check all you suspension to see if a bushing has rotted away. I remember I had a clunk at pretty random times and it ended up being a sway bar bushing had rotted away.

The clunking noise occurs when I first press the brakes until I come to a complete stop - the only thing I should note is that the noise seems like it's rotating, and obviously the noise slows down and I get to &lt;5MPH til I finally stop.

The noise does not seem to occur if I mash the brakes because I was curious about that as well - but I only did that twice, I'll try mashing them some more and see if it happens.

Interesting - thanks for the post.

Check your rotor for runout. If it wobbles back and forth, it may not be seated on the hub properly and can cause a similar noise.

 

Yep, no need for rotor screws.

Jack up the wheel in question, and with the tire still bolted up with the lug nuts, grab the wheel at a 3 and 9 o'clock position and try to move the wheel back and forth. Also do this at the 12 and 6 o'clock position. If there is any play in the wheel bearings, ball joint, or tie rod, you will be able to feel the loose motion. The wheel should have no play in any direction, it should be solid.

I am not saying that any of these items are bad, just trying to rule them out. I have also observed bad axles under braking can make the noise you describe. But you will usually have clicking in turns by that point.

On a side note: look at your crank pulley, see that big chunk missing? Mine looks just like that. I also think I might have the same jack you are using. Is it a low profile jack?
