Brake Booster 11' Delco w/o Stamp

The Brake Booster 11' Delco w/o Stamp is a heavy-duty power brake booster engineered for vintage and classic vehicle restoration, street rod builds, and high-performance brake system upgrades. Weighing 10.48 lbs with an 11-inch outer diameter, this Delco-specification unit delivers the hydraulic multiplication necessary to reduce pedal effort while maintaining precise brake modulation—critical for drivers who demand responsive stopping power without excessive foot pressure. Built by RIGHT STUFF DETAILING, a trusted name in chassis and braking system restoration, this booster integrates seamlessly into applications requiring vacuum-actuated brake assistance without additional stamp modifications.

This vacuum diaphragm brake booster utilizes steel construction with cadmium plating for corrosion resistance and durability in demanding underhood environments. The 11-inch diameter design provides optimal displacement and reaction force, translating engine vacuum into measurable hydraulic pressure that multiplies foot-pedal input at the master cylinder—allowing modern stopping standards on vehicles with manual or power-assist braking requirements. The cadmium finish protects against oxidation and salt spray, extending service life in both street-driven and show-quality restorations. The stamp-free configuration offers flexibility for custom installations where original stamping or specific identification markings are not required or desired.

This brake booster suits restorers, hot rod builders, and brake system specialists upgrading vehicles to modern safety standards while maintaining period-correct aesthetics. Installation requires integration with the engine's vacuum supply and connection to the master cylinder, making it essential to verify vacuum availability and master cylinder compatibility before purchase. The compact 11.95 x 11.8 x 12.05-inch footprint allows mounting in space-constrained engine bays typical of classic and early-model platforms. Whether converting a manual-brake vehicle to power-assisted stopping or refreshing a worn OEM booster, this RIGHT STUFF DETAILING unit delivers proven reliability and measurable pedal feel improvement for enthusiasts who prioritize both performance and authenticity.
