Re: Kanter disc brake conversion

Your offset in the pushrod appears to be about two inches.
Normal braking pressure with discs can run over 800 psi. Without the benefit of boost and with a 1" diameter piston that will require a 628 pound push, for example if the engine stalled or some other goofy thing occurred.
628 lbs linear force applied to the pushrod and working through that 2" offset creates a 105 lb-ft bending moment in the pushrod. Hmmmm. So I welded a nut to an old brake pushrod and applied 120 lb-ft of torque.
