Porsche Power Brake Booster OEM 99735502502 is a used genuine part, also superseding 99735592300. This assembly assists brake pedal force by using engine vacuum to multiply input, making stops feel light and controlled. When it fails, the pedal turns hard and braking effort increases noticeably. Fits naturally aspirated and turbocharged H6 engines across the 911, Boxster, and Cayman ranges.
