Brake Squeal Issue
Aston Martin has identified an issue with brake squeal on certain vehicles with steel brake discs, particularly at low speeds and in low temperatures.
Diagnosis and Repair
Technicians are advised to perform a road test and visual inspection of the brake discs, pads, and wheel mounting face for signs of external contamination.
The PicoScope NVH kit can be used to help identify brake noise and measure acceleration and deceleration during the brake bed-in procedure.
Brake pads must be replaced if contaminated, and the manufacturer’s part number must be checked to find the correct Aston Martin part version.
Customer Education
Aston Martin recommends educating customers on the proper use of cleaning products to avoid contamination of brake pads and the importance of regularly applying heat to the brakes to reduce noise.
