Wilwood 340-13832 Forward Swinging Dual Brake Master Cylinder Pedal Assembly For Two Master Cylinder

This pedal assembly was designed for 4 wheel brakes. One master cylinder will feed your front brakes and one master cylinder will feed your rear brakes. Inside the pedal arm there is an adjustable uniball. For a tandem brake master cylinder pedal assembly, offroad trucks and buggies will have more bias to the rear brakes. 60% rear and 40% front is a common starting point, with a lot of offroad racing vehicles ending up at 30% front and 70% rear. Opposite of a street vehicle.

The bias bar inside the pedal arm is 3/8". It can be upgraded to 7/16" if you purchase Jamar or Tilton's brake bias balance bar if you're concerned about bending Wilwood's 3/8" bar.


When selecting master cylinders, you'll notice with a smaller bore, you get more pressure but less volume. With a larger bore you get less pressure but more volume. You need to make sure that you have enough volume to supply your brake calipers, but at the same time, enough pressure.

On the right hand side clevis you'll notice a tiny slotted screw with a jam nut. The tip of that screw has a spring loaded ball that clicks into a groove cut into one side of the 3/8" shaft. Every 360 degree revolution, the ball snaps into that groove. If you're using a dash mount bias adjuster knob that already has a detent click, then you can simply remove the slotted screw from that clevis.
