Brake lining wil stay within its designated friction range on properly maintained brakes, throughout the temperature range described only under three conditions :
- That the rated axle capacity of the brake material has not been exceeded. If this condition is present, more than normal fade can be present at higher temperatures.
- That at temperatures above 850°F, the driver does not over-speed the vehicle where severe or sudden braking can be expected. Under safe operating conditions, the brake lining on a properly applied and maintained brake will remain stable at high temperatures. Excessive speed while the brakes are hot may result in longer stopping distances.
- That the brake lining is not contaminated with oil or grease.
