What this part does
The brake booster is a vacuum-actuated component mounted on the firewall directly behind the brake master cylinder. It utilizes engine vacuum to multiply the mechanical force applied to the brake pedal, significantly reducing the physical effort required by the driver to stop the vehicle. If the internal diaphragm tears or the unit develops a vacuum leak, the brake pedal will become exceptionally stiff and heavy, leading to increased stopping distances and reduced braking control.

Before you order
Verify that your original factory part number matches GHP9-43-800 exactly before purchasing. When replacing this assembly, thoroughly inspect the vacuum line and the inline check valve, as a simple vacuum leak can often mimic the symptoms of a failed booster. It is also highly recommended to inspect the rear seal of your brake master cylinder during installation; brake fluid leaking into the booster housing will quickly degrade the rubber diaphragm and cause premature failure of the replacement part.
