This power brake booster amplifies the leg pressure you put on the brake pedal. That lowers the pedal effort needed to apply the brakes with full stopping force.
A faulty brake booster can leave the pedal feeling mushy or unresponsive. If a failed booster is the cause, this SKP unit replaces it and is designed to help return a firm, confident braking feel. Other brake components can produce similar symptoms, so have the brake system diagnosed before replacing parts.
