* Brake pads. The most common cause of brake squeal is worn-out brake pads. When the brake pads get thin, they can start to vibrate against the rotors, which causes the squealing noise.
* Brake rotors. If the brake rotors are warped or damaged, they can also cause the brakes to squeal. Warped rotors can cause the brake pads to vibrate, while damaged rotors can create a grinding noise.
* Brake calipers. If the brake calipers are not properly lubricated, they can also cause the brakes to squeal. When the calipers are not lubricated, they can bind up and cause the brake pads to rub against the rotors, which can produce a squealing noise.
* Wheel bearings. If the wheel bearings are worn out, they can also cause the brakes to squeal. When the wheel bearings are worn out, they can allow the wheels to move around, which can cause the brake pads to rub against the rotors and produce a squealing noise.
If you're not sure what's causing your G35's brakes to squeal, it's best to have them inspected by a qualified mechanic. They will be able to diagnose the problem and recommend the best course of action.
Here are some tips for preventing brake squeal:
* Replace your brake pads before they get too thin.
* Have your brake rotors inspected and replaced if necessary.
* Lubricate your brake calipers regularly.
* Get your wheel bearings inspected and replaced if necessary.
