1. Hard Brake Pedal: If the brake pedal feels unusually hard or stiff when you press it, it could indicate a loss of power assist from the brake booster.
2. Increased Pedal Travel: You may notice that the brake pedal travels farther than usual before engaging the brakes. This can be a sign that the brake booster is not providing enough vacuum or hydraulic pressure to assist in braking.
3. Squealing or Hissing Noises: Listen for any unusual noises when you press the brake pedal. A squealing or hissing sound can indicate a vacuum leak in the brake booster or related components.
4. Reduced Braking Power: If you feel that the brakes are not stopping the vehicle as effectively as they should, it could be due to a failing brake booster. The reduced power assist makes it more difficult to generate sufficient braking force.
5. Illuminated Warning Lights: Some vehicles have brake booster warning lights on the dashboard. If this light is illuminated, it indicates a problem with the brake booster or its related systems.
6. Engine Stalling: In vehicles with vacuum-assisted brake boosters, a faulty booster can cause excessive engine vacuum, leading to engine stalling or rough idling.
7. Unusual Brake Feel: The brake pedal might feel spongy, soft, or inconsistent when pressing it. This can be a sign of a problem with the brake booster or a related component.
If you suspect a brake booster failure or experience any of these signs, it's crucial to have your vehicle inspected by a qualified mechanic as soon as possible to ensure safe braking performance.
