    Strange question. But what's the diameter of the bolt that attaches the piston in the master cylinder to the handle on a hydraulic handbrake?

    Surely that'll depend entirely on which 'brand' of hydro you're running? Just measure it?

    I don't have on here yet. Either Ordering an OPB pro spec or making my own (engineer by trade) say if I used the master cylinder off the driftworks one, what would the bolt size be on that?

    The driftworks handbrake uses a wilwood o.625 with a 5/16" threaded section into the master cylinder, so you'd need a clevis to fit onto that thread size, the dw one looks like quite a chunky clevis compared to some of the available options on demon thieves etc.
