TaoTao Quantum Disk Brake Issues

[WontonScoot]

Hello all, Here is the rundown of my Scooter
TaoTao 150cc Quantum/Titan Purchased brand new March 2021
Got it off Amazon
Shipped in a crate to my door.
Right now 340 miles on it
I had to assemble few parts on it including the front rim/tire

Ok here is the issue with the front brake which is a disk brake setup.

When the scooter is pushed forward there is a rattle coming from the front caliper. When the Scooter is traveling down the road there is a rattle in the front caliper.
Now I have taking the caliper off. It has two allen head bolt/screws on the back side you have to pull to get the pads out. The Pads look brand new and no defects to them. There is a upside down like triangle pressure spring/metal thingy in that looks perfect and I have inserted it back proper. I have assembled it all back and tightened down the two Caliper Mounting bolts and they are very tight. For the life of me. I can't figure out where that rattle is coming from. The Brakes work fine.. it is just that rattle sound that has me puzzled. I have taken that caliper off like 8 times now to try and solve it. Unless the Caliper is just plain out defective.
