High Volume Tandem Master Cylinder - 1” Bore
One inch bore. Tandem body. More fluid per stroke.
A master cylinder is where pedal feel is decided. Move too little fluid and the pedal sinks while the calipers are still waking up; move the right amount and the truck stops the instant your foot asks.
That is what the high volume design buys you. A 1 inch bore with a tandem body feeds a big four wheel disc setup without the long travel that makes a converted truck feel vague.
Tandem also means two separate circuits from one casting. Lose a line and you still have brakes on the other half; which is the whole reason a modern brake system is built this way.
Pick your finish: raw metal for a machined look under the hood or black when you would rather the hardware disappear.
- High volume for big brakes - it moves the fluid a four wheel disc conversion actually needs.
- 1 inch bore - firmer pedal and shorter travel than a small bore cylinder pushing the same calipers.
- Two circuits from one casting - a tandem body keeps half the brakes alive if a line lets go.
- Two finishes - raw metal to show the machining or black to let it sit back under the hood.
- Wilwood build - a brake manufacturer that publishes a part number you can match to the rest of the system.
