I've heard that the M90 & M109 front master cylinders look identical but the internals are different to handle the dual calipers on the 109. Anyone know the effect of the M90 Master Cylinder on a M109 would the braking power be reduced or could it cause a pulsing effect or ?. Any first hand experiences or logical thoughts?

Thanks

Can't say for positive but usually a dual disc system master is sized to produce a set psi at a set volume of fluid displacement. A single disc unit would require less volume but more than likely the same psi. So my guess is that they would be different internally.
