Strange clicking noise when braking ( 06 GT )

[terror]

I installed a new set of drilled/slotted rotors and pads on my GT and for some reason whenever I brake during the first time of driving that day ( after the car has been sitting for a while) there is a loud annoying clicking noise that comes from the front of the car, it is more noticeable when braking at an incline. It didn't do that before the pads and rotors were changed, any ideas as to what this clicking noise could be?

Edit: Just to be clear it clicks when I press the brakes after it has been sitting overnight. Once it clicks and I continue to drive/brake, the noise is gone until I park it for the night. Then ill drive it the next day, it'll click once again, be fine for the rest of the drive/day and then repeat the same annoying first drive click the next day.

DID YOU SEAT the pads after install i.e.: Burn them in ? if not that may be your problem. Try burn them in i.e.: seating them to the rotors. This is done by driving 40mph and breaking to 5mph do this three times then drive 60mph and break to 10mph do this three times. Then drive at least five miles without breaking to coll the rotors this will seat the pads to the rotors.

/\ I think you mean “bedding”

OP - is it possible that there’s some oxidation on the rotors that is being knocked off on first application of the brakes?

Yes, I did. Would it be worth it to try and do the process again?

I'm not quite sure what you mean by this, if you could explain, that would be appreciated.

the rotors are rusting and the pads are sticking some since the car sat for some period of time.

Brake rotors are made of metal. No matter where you are in the world there will always be some moisture build up on metal when it sits for any period of time. It is very possible that overnight you are experiencing a slight surface rust that might not even be visible to the eye but enough to create the noise.

So is there anything that can be done about this, or am I doomed forever . It is pretty obnoxious.

NO if you seated the pads then nothing can be gained by doing them again. Maybe have someone in the car put it in gear and slow back up while someone else with a flashlight kneels by the front wheel looking and listening for the clicking. Maybe then you can figure out whats clicking and see how to stop it.

Rotors with slots or dimples will sometimes make a clicking sound. I only notice mine when I’m braking next to a concrete wall. It is due to the expansion of air as the slots or dimples pass by the pads or something like that. I can’t remember if I read about it on the EBC website or talking with the guys at SEMA.
