This 1967-1970 Mustang 9" Chrome Single Diaphragm Brake Booster includes Push Rod Boot & Check Valve. This is an exact duplicate of the original finish and includes the pushrod boot and check valve already installed.
With this vacuum level the booster will produce a maximum pressure output of 1100 psi with a 1" bore master cylinder. This pressure level will work great for disc/drum vehicles.
This booster is recommended for heavy disc brake cars.
The 9" booster requires 18" of vacuum to operate properly.
