2020-01-28 - Brake Line Encasement

Q.
We have purchased a brake proportioning kit from Flyin Miata.

We will be installing the adjuster inside the car next to the driver. Do we have to cover the brake line going to the adjuster? Is so, what do you suggest to us to cover the brake line. We are using a 3/16" steel brake line.

A.
Brake lines do not need to be encased.

Only fuel, oil and coolant lines need to be encased.  Any fuel, oil, or coolant lines (including Aeroquip steel braided lines) that pass through the driving compartment must be metal or encased in continuous steel conduit or aluminum tube. (Flex-conduit is not acceptable. Lines wrapped in the aluminum tape are not acceptable.)
