[Roadsters] Right rear brake cylinder leak

[Stan Chernoff]

Dave,

The hex dimension on the tube fitting for the rear brake cylinder is 
7/16" .  While 11mm is close to 7/16" you would waste your money if 
you purchased metric tubing wrenches to work on a Datsun roadster 
since all of the brake tubing fittings are SAE.
