Use a rod with more threads per inch. They make coarse threaded rod, which is often around 20 tpi, which you might be using, as well as fine threaded rod, which gets up to 28+ tpi.
Okay, but how would you use a caliper, if the vehicle is so thin. The wider it is, the easier you can tell the numbers apart on a caliper and the more accurate. Would you just have to get a better caliper? I am using 1/1000 inch and it is not accurate enough. If I made it less than 20cm, it would not be close. How did you solve this problem?

Sorry, my kids don't use a caliper. My post was specifically in reference to your braking question.

Maximize the length the buggy to increase the wheelbase. A larger wheelbase results in better 'precision'.

Wdym?

I don't think I have the same design, at least... but again I haven't seen your buggy so ¯\_(ツ)_/¯
