I found the problem and it was the both sides front pad brake and brake rotors was gone. Also, I check the brake caliper function it work great but now I have problem with the replacement pad brakes because the dealer only have one type ACDELCO and it was (made in China) I ask him if he have another one (made in Mexico or USA) but he say no. Finally, I found one in small old stock spare part shop but not GM or ACDELCO it was another brand which is called ROTEX and it is (made in Canada) and price also good now when I try to install the I notice that NO brake shim on it including the hardware that hold pad brake in it place and I use the old ones but the old one already have two of these holders are missing. Also, This store have brake rotor which the dealership itself don't have it at all and it called Bendix PRT5241 and he told me this is good brand and it is (made in USA) is this right and .

Does anyone try this brake rotor?
What can I do?

thank you
