Wilwood 340-14769 Single Upright Handle Handbrake For Drift Cars, Drag Racing, Rally Cars, Offroad

It has a lightweight forged aluminum "H" beam lever and an ergonomic grip. Available in a choice of an upright vertical or an angled horizontal lever position.


When selecting a master cylinder, 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.

Just like a pedal assembly, here is an example of the math. Pulling the handle with 100 pounds of force, a 7.54:1 ratio and a 3/4" bore master cylinder:

Force at master cylinder:
100 lbs x 7.54:1 ratio = 754 lbs

3/4" master cylinder area:
A = π r²
A = 3.14159 x 0.375 x 0.375
A = 0.4418 in²

Line pressure:
754 lbs ÷ 0.4418 in² ≈ 1707 PSI
