Buying Guide: Key Purchase Considerations
- Vehicle compatibility: Check bore size, master cylinder type, port configurations, and mounting patterns to ensure the kit matches your brake system and vehicle year/model.
- Booster size and mounting: 7″ and 8″ boosters are common; consider space in the engine bay and under-dash clearance. Ensure bolt patterns align with your pedal assembly and firewall.
- Master cylinder style: Bail Top, dual-bowl, and single-diaphragm designs affect mounting and plumbing. Match to your braking configuration (disc/disc, disc/drum, etc.).
- Proportioning valve and lines: A built-in or included PV kit helps balance front and rear brake forces, important for performance and safety on various vehicle types.
- Installation complexity: Some kits include brackets, lines, and switches, making a complete install easier. Others may require fabrication for a perfect fit.
- Durability and materials: Powder-coated finishes resist corrosion; cast iron components offer longevity. Consider climate and usage (daily driving vs. show builds).
- Vehicle-specific fitment notes: Muscle cars from the 1960s-70s and early classics often need precise valve and line configurations; verify compatibility with your chassis.
- Safety features: Ensure the kit includes or accommodates a brake light switch and proper mounting hardware for a complete, compliant installation.
