    In response to Mel Foye

1/4" line will be a bit more difficult to bend and route than 3/16" line, but if you'd prefer to use it from pedal to wheel, go ahead. It won't cause any adverse issues.

  • Mel Foye Said:
...the larger the line the more pedal travel will be needed.

The larger diameter won't affect pedal travel. It will simply require slightly more brake fluid when initially filled.

  • japete92 Said:
Because pipe diameter impacts pressure...

It's a closed system. The pipe diameter does not affect the line pressure.

You're likely thinking of the master cylinder and caliper/wheel cylinder piston diameters (and their related areas). The former area affects how much pressure is generated for a given input force, while the latter affects how much force is exerted by a given line pressure.
