yeah I think it is 1/4" also...
not to split hairs but....technically the size of the line doesn't change the pressure, it changes the volume...the difference in pressure is determined by the piston/wheel cylinder diameters in relation to the master cylinder(hydraulic multiplication) and the amount of force applied to the master cylinder.
there will be less pressure applied to the wheel cylinder because the wheel cylinder cups have less area than the caliper piston due to PSI (pounds of force per square inch) not to even go into the metering and proportioning....
that is my understanding anyway
