Dual Master Cylinder - 1.032" Bore
Includes Dust Boot, Pushrod, & Fittings


Part Number: B3360TA

Vehicles with front and rear manual disc brakes
Normally used with single or two piston calipers in front and four piston in the rear
This is assuming Drag Race brakes as factory calipers may require more fluid volume
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

5.5 to 1 pedal ratio

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