A failing Regal power brake booster often shows up in a high, hard pedal that needs greater than normal pedal engagement to stop your car. Another symptom is that you need more distance than average to halt your vehicle, and this potentially means you're not receiving a power boost. A perfectly working system should give you power assist when you first apply the brakes at all times with normal stopping length, pedal travel and pedal pressure. Buy a new Buick Regal brake power booster from AutoZone and enjoy Same Day Store Pickup (in most cases).
