2005 Infiniti G35x - squeaky brakes only when backing up slowly

Question

Don't squeak when braking forwards, or braking hard/fast backing up. Only when backing up and lightly pressing on them. Extended squeal, and very loud.

Anything I can do?

Answer 1

You should take it to a reputable mechanic or dealership. Your breaks are the most important part of your car and if you suspect something is abnormal take it in to get an inspection.

Answer 2

This sound usually comes from resonance when pads sharp edge touches the disc slightly or a small piece of stone stuck on the pad. Usually it's not serious and will go by itself after braking several dozen of times, but if you want to be safe - get the car to the service-shop and ask them to take a look and maybe grind the pads sharp edge.

Other more serious options, that probably do not apply to your description, as they would produce sound at both directions and range of braking forces:

• cheap/not-original pads that wear unevenly;
• you could have damaged your discs with hard breaking, they overheated and are no longer flat.
