The 9in Single Diaphragm 67-70 Mustang Booster Gold by TUFF-STUFF is a direct-fit power brake booster engineered for early second-generation Mustang models seeking improved stopping performance and pedal feel. Built for restorations, street builds, and drivers who demand reliable hydraulic assist without sacrificing authenticity, this booster restores modern braking confidence to classic muscle cars. Whether you're upgrading from a worn original unit or transitioning from manual brakes, this booster delivers consistent, fade-resistant stopping power across varied driving conditions.
The single diaphragm design uses vacuum-assisted hydraulic multiplication to reduce pedal effort while maintaining linear, predictable brake response—critical for vintage Mustangs where driver feedback matters. The 9-inch booster size is purpose-built to fit within the original engine compartment footprint, preserving underhood aesthetics and clearance around headers, intake manifolds, and alternators common to small-block and inline six-cylinder conversions. Gold anodizing provides superior corrosion resistance in harsh underhood environments, preventing oxidation that degrades performance seals over time. Internal valving and composite piston design withstand repeated thermal cycling without loss of vacuum integrity or delayed brake application.
This booster is ideal for restorers, hot rodders, and Mustang enthusiasts pairing stock or modified drum-to-disc brake conversions on 1967–1970 first-generation models. Installation pairs seamlessly with factory master cylinders and contemporary disc brake systems without adapter fabrication. Proper vacuum sourcing from a running engine is essential—ensure your intake manifold or electric pump delivers 18–22 inches of mercury at idle for optimal booster operation and longevity. Weight and compact dimensions allow mounting without transmission tunnel modification, making this a bolt-on solution for both original restorations and performance builds.
