Disc brake Master Cylinder and Proportioning Valve Kit

Disc brake Master Cylinder and Proportioning Valve Kit
Part #:MCPVS-2
Brakes Type


Our disc master cylinder with AC Delco type proportioning valve is just what you need to finish your disc brakes. Our unique setup includes a master cylinder bore adapter to allow you to use it for manual or power disc applications. Our master cylinder has a 1.00" bore diameter which creates more line pressure for manual brake applications and makes your power brake application feel much better than larger bore setups. Proportioning valve utilizes a lower pressure shut off valve for safety, should line pressure ever become compromised. Kit includes low pressure warning light wire and plug. Master cylinder accommodates both Ford and Chevy mounting bolt batterns. Designed for firewall mounted brake systems
