Power Brake Booster

The RIGHT STUFF DETAILING Power Brake Booster with Master Cylinder Kit (MPN: G81310572) is a complete single-diaphragm brake system designed for General Motors applications requiring robust stopping performance. This dual integral reservoir assembly combines proven booster and master cylinder architecture in one integrated package, delivering consistent brake line pressure across a variety of GM vehicle platforms. The 1-inch bore master cylinder and 8-inch OD booster housing are engineered for vehicles where OEM replacement or restoration demands a factory-spec brake system without proprietary sourcing complications.

The cadmium-plated steel construction provides corrosion resistance critical for long-term reliability, particularly in vehicles stored outdoors or operated in humid environments. Single-diaphragm design simplifies maintenance compared to dual-chamber boosters while maintaining adequate brake assist across normal driving conditions. The dual integral reservoir eliminates external fluid lines between master cylinder and booster, reducing connection points and potential leak sources. At 21.7 pounds, this assembly integrates compactly into engine compartments with space constraints, though the 11.7 x 9.6 x 19.1-inch footprint should be verified against your specific vehicle's brake bay dimensions before ordering.

This kit suits restorations and replacements on various GM models where period-correct or OEM-equivalent brake systems are required. Classic car builders, fleet technicians, and restoration shops rely on complete brake booster kits to avoid sourcing components separately and managing compatibility across different manufacturers. Proper installation requires brake line adaptation, master cylinder bore verification, and pedal travel adjustment specific to your vehicle platform—consult factory service documentation or a certified brake technician before installation.

RIGHT STUFF DETAILING offers this as a complete kit rather than individual components, streamlining the brake system overhaul process for GM enthusiasts and professional shops managing multiple restoration projects. Sourcing a master cylinder and booster separately introduces risk of incompatibility or mismatched bore sizes; this integrated solution eliminates that concern.
