Aston Martin has issued a recall for its Valkyrie hypercar due to a unique brake issue that can lead to brake dragging and potential fires. Models equipped with the track suspension are susceptible to having a seal within one of the brake master cylinders deform. The recall affects seven 2024 Valkyrie models.
The issue occurs when the Valkyrie is driven in a very specific way, which isn't possible when driving on public roads. According to the recall report, the conditions below must be met simultaneously for the brake dragging to occur: the car must be driven aggressively, the disc temperatures must be elevated, and the brake fluid must build up to a certain saturation point.
If the seal deforms, it can cause a cascade of problems. It first prevents brake fluid from returning to the reservoir when the brake pedal is released. If this happens, the brake pressure won’t be released. If enough fluid builds up to a certain saturation point, the brakes could drag on the brake disc. If the disc temperatures are already elevated and the car is being driven aggressively, the brake discs could heat up enough to ignite the resin in the carbon-fiber rear brake cooling duct.
Aston Martin will instruct affected owners to take their vehicles to a dealer, where a service technician will replace the brake master cylinder with a new part designed to operate with ESP and traction control. The repair will take up to five hours to complete.
