67-72 GM Car/Trucks Master Cylinder Dual Blk

The 67-72 GM Car/Trucks Master Cylinder Dual Blk is the ideal upgrade for anyone restoring or modernizing a classic General Motors vehicle from 1967 to 1972. Whether you're rebuilding a Chevrolet, Pontiac, Oldsmobile, or Buick, this slimline master cylinder provides the hydraulic foundation your braking system needs. Built by RIGHT STUFF DETAILING, a trusted name in classic car restoration parts, this master cylinder replaces outdated and potentially compromised originals with a precision-engineered unit designed for reliability and smooth brake modulation on street and weekend-drive applications.

This master cylinder features a compact 1-inch bore and dual integral reservoirs housed in a slimline aluminum body with a professional black finish. The dual-reservoir design eliminates external brake fluid lines between front and rear circuits, reducing complexity and improving system cleanliness—critical for vintage cars where hidden corrosion can compromise hydraulic integrity. The integral design also shortens response time by minimizing fluid travel distance, translating to firmer pedal feel and more confident braking modulation. Aluminum construction keeps weight minimal while maintaining the thermal conductivity needed to dissipate heat during extended driving, preventing fluid degradation and brake fade.

This kit is purpose-built for enthusiasts performing complete brake system overhauls on first-generation F-body and mid-size GM platforms from the late 1960s and early 1970s. Installation is straightforward on stock mounting locations, and the slimline profile clears many engine bay configurations without requiring custom fabrication. Pairing this master cylinder with modern brake lines, calipers, and DOT-approved fluid transforms a classic car's stopping power while maintaining period-correct aesthetics under the hood. Weighing 5.69 pounds, it's a direct bolt-in solution that eliminates guesswork and delivers consistent hydraulic pressure across both brake circuits.
