Rear brakes?

Hello,

Usually popping noise happens from suspension and drivetrain parts and not from the brakes. Typically popping noise will happen when you have a worn busing or broken suspension part.
As you mentioned it happens when you turn left.
What happens when you apply the brake?
If the noise does not change with the brake then it is likely not a brake issue.

Here is a helpful article on popping noise:

Please let me know if you have any questions.

Thank you.
