A power brake booster, also known as a brake servo, is a critical component of a vehicle’s braking system. It utilizes vacuum or hydraulic pressure to amplify the force applied by the driver on the brake pedal, reducing the effort required to stop the vehicle. However, like any other component, power brake boosters can deteriorate over time and develop issues that may affect the overall braking performance. Recognizing the signs of a faulty power brake booster is essential to ensure the safety and reliability of your vehicle.
One of the primary indicators of a failing power brake booster is a noticeable increase in the effort required to press the brake pedal. This added resistance can make braking a more challenging and tiring task, especially during emergency situations. Another common symptom is a spongy or soft brake pedal, which fails to provide a firm and responsive feel underfoot. This lack of firmness can make it difficult to modulate the braking force effectively.
