Toyota Prius: Brakes

Affects Toyota Prius · 2010 — about 4K vehicles.

The hazard

On certain vehicles, a fatigue crack could develop in the brake pressure accumulator. If this occurs, nitrogen gas could leak into the brake fluid and gradually cause the brake pedal stroke to become longer, resulting in decreased hydraulic pressure. This condition could result in longer stopping distances, increasing the risk of a crash causing property damage and/or injury. Correction: dealers will inspect the brake booster pump and, if necessary, replace it with an improved unit.
