Popping/clunking sound from the front wheels during braking?
I was driving home after a track day and I noticed a popping/clunking sound from my front wheels (probably the right one) during braking.
Any ideas what this might be?
I have a few aftermarket pillowball bushings on the lower arm and a few in my coilovers, but I wonder if this sound could be coming from the brakes?

My guess would be brakes or wheel bearing. Pull the wheel and tug/mess around with it.

The right front seems to lock up before the left front, although I figure that's driver weight (RHD car).
OTOH, my rotors are starting to get pretty worn and my $$$$$ race pads still have life left, so I might just get them turned and keep using the pads after a bit of sanding.

Maybe it's related or not but my buddy was chasing a similar sound when braking on his 2010 Acura TL.
So he started with the tie rod IIRC than the swaybar link , than the lower control arm , than the wheel bearing . We were running out of things to change and the sound was still there. that's when we decided to change the upper control arm that the sound was gone, haha .
What an adventure it was chasing that clunk.

Do you think that might also effect which brake locks up first?

It's counter-intuitive, but I don't think driver weight tends to the front corner on the side you're driving on.
Preloaded sway bar is a possibility but I don't have adjustable links.
I'm pretty sure the arms moved freely without the shock or sway bars attached.
I'm getting the calipers rebuilt today, hopefully.

A while back some guy came to my house and mentioned a clunking on the front.
Turns out the 4 pot caliper's Bracket bolts were loose.
Just mentioning that as a guess...maybe because you said Racing pads..so it leads me to believe that you changed pads at some time or another.
Good luck to ya though..You need a good solid front end..and of course good brakes if you are tracking the car.

I take it back; two of them (out of four) weren't totally torqued, but they will still in place (paint pen marks were spot on). It probably wasn't the cause of the clunk, though.
I think it's good practice to go on wrench patrol whenever you have an off-track excursion with an FD... especially if you have pillowball bushings.

I had much less pad left than I thought... still not past the groove, though.
