- Aston Martin will recall seven 2024 Valkyrie hypercars.
- They are equipped with track packages, and when driven under certain conditions, the seal in the brake master cylinder may deform.
- If this happens, the brakes may stretch, and, in combination with other factors, the rear brake cooling duct may catch fire.
Aston Martin has issued a recall for its Valkyrie hypercar. Track suspension equipped models are susceptible to a damaged seal within one of the brake master cylinders.
Remembrance affects seven—that’s right, only Seven-2024 Valkyrie Model. If the seal deteriorates, it can cause a number of problems. This first prevents brake fluid from returning to the reservoir when the brake pedal is released. If this happens, brake pressure will not release.

If enough fluid accumulates to a certain saturation point, the brake fluid can drag on the brake disc. If disc temperature is already elevated and the car is being driven aggressively, the brake disc may become hot enough to ignite the resin in the carbon-fiber rear brake cooling duct.
Thankfully, the problem only comes to light when the Valkyrie is driven in a very specific manner, which is not possible when driving on public roads. according to recall reportThe conditions below must be met simultaneously for brake dragging to occur:
- The car is being driven in a track environment.
- The Electronic Stability Program (ESP) should be set to Sport, Track or Off.
- Valkyrie is in an oversteer slide or drift and has exceeded the yaw rate and body slip angle limits.
- The driver is counter-steering so much against the oversteer situation that the ESP intervenes, braking the front inside wheel while the front outside brake builds fluid pressure.
- Valkyrie would be sliding sideways at very high speed.
- The driver must use the throttle during or just before braking to prevent the ESP from intervening on the rear inside wheel.
- Brake pressure will be applied to the rear inside wheel to stop it from rotating.
- The driver must then apply force on the brake pedal at the same time as both the front and rear brakes are already loaded due to the ESP intervention circuit.
If all this happens, the driver’s braking and ESP activation will cause brake pressure, causing the brakes to drag. This will happen without warning, but the driver must sense the problem through the pedals.
Why is this unlikely to happen on the road?
These problems originated from the Valkyrie’s original brake system design. Aston Martin never intended to feature ESP or adjustable traction control in the brakes, so the system does not allow controlling brake fluid through the pedal and ESP at the same time.
Aston Martin first became aware of a potential problem in November 2022 and immediately began working with its supplier Alcon to determine the cause of the failure. The automaker identified the root cause in February 2025 and began designing a fix, which was ready a month later.
The new portion began in September 2025 and in early 2026, the company’s Critical Concern Review Group reviewed the data to determine a recommendation for Aston’s recall committee. The group decided to issue a voluntary safety recall in late May.
Aston Martin will direct 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.
Motor1’s Opinion: It may have taken Aston Martin almost four years to fix the brake problem, but it’s not something drivers will experience often. The conditions that cause the problem are fairly specific, but they can happen in a car like the Valkyrie, so Aston is smart to play it safe and fix the seven cars that this can happen to.
