spot on dtype, i would just like to add.
rear toe is checked to same way except, you fit the gauages to the rear wheels with the mirror and periscope to the rear of the car and remember that the reading are reversed, so if the gauges read toe out when on the rear the wheels are actually toeing in, but the actual figure will be correct.
d type has said how to calibrate them, by putting the gauges together and zeroing them in, this is very important and needs to be done every time you use them as the design of the gauges means the calibration can easily wander.
also, when checking/ using/ adjusting the car, you must keep checking the pointers are against the cars wheels.
in an ideal world when checking wheel alignment you should check and compensate for wheel/ hub runout the very expensive top of the range all singing and dancing electronic machines do this automatically,
the way to do this is with the dunlop gauges is take a set of readings, and move the car either backwards or forwards by one half of a wheel revolution, and take another set of readings, the true alignment figure will be an average of both figures, hopefully they will be identical, but in the real world often are not
