High Volume Tandem Master Cylinder - 1” Bore

$249.92

Wilwood high volume tandem master cylinder with a 1 in bore for classic truck brake upgrades, built for increased hydraulic pressure. Raw metal or black finish.

  • 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.

Install Level: Moderate

Brake lines, fittings, fluid and mounting hardware not included.
Choose raw metal or black at checkout.
