A hydraulic booster can be tested just like a vacuum booster. With the engine off, pump the brake pedal until you feel firm resistance, then hold. Start the engine. Proper operation should result in the brake pedal slightly sinking. Will I need to retain my master cylinder pushrod? Yes, the master cylinder pushrod, spring and retainer will need to be retained and reused on the replacement hydraulic booster. Will I need to bleed my power steering system after installation? Yes, since the power steering lines have been removed, the system has been subjected to air. The power steering system will need to be bled using the O.E. bleeding procedure. What type of fluid does a hydraulic booster require? As part of the power steering system, hydraulic boosters require O.E. power steering fluid. The main advantages of a power brake booster are: Increased braking power: The power brake booster uses vacuum assist to amplify brake pedal force, enabling quicker and more effective stopping.Reduced pedal effort: It minimizes the physical effort needed for braking, enhancing comfort during prolonged or emergency braking.Consistent braking performance: It ensures predictable braking response regardless of pedal pressure, improving safety.Compatibility: It integrates seamlessly with braking systems like master cylinders and works with both disc and drum brakes.
