1 1/8″ Mopar Dual Master Cylinder

Description

Brake pressure will be delivered equally out of both ports
Use of an adjustable proportioning valve is highly recommended

Using All Wheel Disc brakes
Use 2 lb residual pressure valves if mounted at or below the level of the calipers

Using With Drum Brakes
Any line supplying drum brakes will require a 10 lb residual pressure valve

Recommendation
6.5 to 1 pedal ratio

Note
Port closest to the push-rod flows the most volume of fluid
This port needs to be plumbed to the brakes requiring more capacity
