1967-69 Ford Mustang 8" Dual Midland Ross Style Power Brake Booster | PB8539

PB8539 1967–1969 Ford Mustang 8" Dual Diaphragm Power Brake Booster: Midland Ross Style

Bring your Mustang’s brakes back to factory condition with a brand-new booster that looks and works like the original. The PB8539 is a concours-level reproduction of the factory Midland Ross-style 8" dual diaphragm booster used on 1967, 1968, and 1969 Mustangs. It’s built for restorations where authenticity matters, from the correct teardrop-shaped pushrod to the factory finish under the hood.

It mounts in the original location with no modifications, so it’s a direct replacement for a worn, leaking, or damaged factory booster. The 8" dual diaphragm design delivers firm, dependable power brake assist, and because it’s brand new, there’s no core to return and no guesswork about the condition of a rebuilt unit. It replaces remanufactured booster 54-76201, and shipping is free.

⚠️ IMPORTANT: BLEED BRAKES WITH THE ENGINE OFF
Bleed the brakes with the engine off and no vacuum applied to the booster. Bleeding with the engine running or with vacuum applied will overextend the pushrod and break the booster’s internal parts. Damage caused by bleeding with vacuum applied is not covered and is not eligible for a refund.
