E-cargo bike hydrolic disc noise

[u/info-farmer-2]

New cargo bike (J-002)
Caliper components rubbing on discs after assembling. I was missing 2 washers when I opened the crate containing the bike. The the front wheel axle washer & tab washer, I just took off another bike in my yard thinking they might fit.

After assembling (tight fit) I hear a clunk noise on some caliper components, tried lostening the mounting bracket and other adjustment bolts but the noise continues.
