Is this gap between the caliper and the rotor normal? I have been dealing with break issues for months now. Theres not an issue with performance but there has always been grinding and squeaking. I have replaced the break pads once and the rotors twice. Noise didn't start until break pads got worn down which prompted me to replace them and the rotors. Noise hasn't really stopped since then. When it continued I had suspected warped rotors but after replacing those again, the noise continues.
