What is required in a brake lining gauge?

The requirement in a brake lining gauge is to measure the remaining thickness of the brake lining in fractions of an inch. This measurement is crucial for ensuring the safety and effectiveness of the braking system. As brake linings wear down over time, it is essential to regularly check their thickness to determine if they need to be replaced.

A brake lining gauge provides a precise way to assess whether the linings have enough material left to function properly, helping to prevent brake failure, which can lead to dangerous situations on the road. Monitoring the thickness allows technicians to make informed decisions about maintenance and replacements, thereby contributing to the overall safety of the vehicle.

While color, durability, and replacement history may provide useful information about brake linings, they do not serve the primary purpose of a brake lining gauge, which is specifically to give an accurate measurement of how much lining remains.
