Part Number: B3359

Application
Vehicles with front and rear manual disc brakes
Normally used with four piston calipers in both the front and rear brakes
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
