Power Brake Booster Nut, Nut And Washer Assembly Hex
- Description:
This is a genuine Ford power brake booster nut, the fastener that secures the brake booster and master cylinder assembly to the dash panel inside the engine compartment. Ford dealer catalogs list it as Booster Nut, and it appears in the dash panel components and brake booster grouping where it threads onto the booster mounting studs that pass through the firewall. It clamps the booster firmly against the dash panel so the unit stays located and the brake pedal pushrod geometry remains correct, which is essential for consistent pedal feel and braking response. You will find this nut used on Ford Super Duty trucks including F-250 Super Duty and F-350 Super Duty in regular cab, super cab, and crew cab configurations, both with and without the hydro-boost brake system, with model years spanning roughly 2017 into the mid 2020s. These are representative examples rather than a complete list. A loose or missing booster nut lets the brake booster shift on the dash panel, which can cause a spongy or inconsistent brake pedal, knocking or movement felt through the pedal, vacuum or hydro-boost leaks at the mounting face, and in severe cases compromised braking. Because this is a brake-system fastener and is safety-critical, it must be installed correctly and torqued to the Ford specification, and it is typically replaced whenever the booster is removed and reinstalled. Confirm the correct nut for your specific vehicle and brake configuration against your VIN before ordering.
