I have a 2008 Range Rover Sport HSE, Sometime over the past few months a noise has developed that sounds like a 'pop' when you hit the brakes faster than normal, or go over certain bumps. I have just replaced all rotors and pads last week, and the noise is still there. I have read about several possibilities. I dread taking this to the dealer out of warranty, as I have seen them make mistakes before and wanted big bucks to solve stuff that was not broken. I would prefer to identify the noise myself and then see if I can find cheaper options to fix it if at all possible outside of the dealer. Thanks for any suggestions.
