Porsche 911 brake vibration issue when stopping or backing up, no solution found on Porsche 911

Some Porsche 911 owners report experiencing brake vibration issues when stopping or backing up, which can significantly affect the driving experience. This vibration, particularly noticeable under heavy braking, may result from uneven wear on the rear disc or rotor, often caused by brake dust or rust buildup. Owners describe the sensation as similar to an out-of-balance tire, especially during semi-hard braking from speeds over 50 mph. Additionally, addressing brake squeal in a luxury vehicle like a Porsche requires a systematic approach, including cleaning, component replacement, or changing brake pad materials. To mitigate brake squeal, some owners find success using anti-vibration shims and metal-free lubricants. If standard maintenance procedures, such as cleaning and inspection, do not resolve the vibration issue, it is advisable to consult a reputable Porsche parts supplier or qualified technician for the best brake pad options, as some replacement pads come equipped with vibration damper backing plates. If the problem persists, seeking assistance from a Porsche specialist for a thorough inspection may be necessary to effectively address the brake vibration concern.
