Clunk/rattle coming from brakes or wheel area

[zeddzik]

Hey everyone so I just switched out my brake pads to my track pads for a track day this weekend and I've been hearing a rattling coming from the front wheels or brake calipers.

It definitely rattles a lot when going over bumps but when I put some pressure on the brake pedal it seems like they quiet down a bit. The rattle can't be felt though the steering wheel but its pretty loud.

Also I noticed when backing into my parking spot at work that when braking to a stop then baking up, as soon as I brake I hear a clunk definitely coming from the front brakes.

My car has a little over 11000 miles, any Ideas of what this could be?

Have you checked every bolt you touched during the brake job to make certain they are still torqued?

Inside /outside pads installed correctly?

Few good suggestions so far - also, did you make sure you have enough rotor left for new pads?

Thanks for the input guys! @kivnul you were correct. I didn't have time to fully take everything off and check on my lunch break but I did have time to try and get a slow-motion video of what the front right caliper was doing when it was making the clunk on reverse... here's what I captured: https://photos.app.goo.gl/3QPPiQmirTtLHETu8

So this was worrying to say the least... I immediately used the spare jack and wrench and went to take a look. Lo and behold I forgot to torque the two most important bolts when doing a break job, the two actually holding the caliper onto the hub. They backed themselves out so far that one was almost out of thread Fortunately I was in a Ford Dealer parking lot at the time and was able to convince one of the techs to let me borrow a 15mm socket to get them torqued down enough to get me home.
