Minimum brake disc thickness

Textar produces its brake discs as near as possible in form and thickness to the OE specifications. The specified minimum thickness is the absolute minimum below which the disc may not be used anymore. When this value is reached, the brake disc must be replaced, as it will no longer work reliably and safely. This value is determined by the vehicle manufacturers at the design stage.

Factors such as heat dissipation and the relationship between disc, pad and calliper are taken into account, as these must be matched to each other. Worn discs have a lower thermal conductivity. This can cause excessive heat accumulation in the brake system, resulting in serious problems, such as cracking of the disc or vapour bubbles in the brake fluid, which would dangerously impair braking performance.

The brake disc’s minimum thickness is not the only factor to pay attention to when inspecting a brake system. The tyre tread depth and remaining brake pad thickness must also be checked regularly to ensure that the vehicle achieves its optimum brake reaction.

If brake discs wear beyond their specified minimum thickness, they may be destroyed under extreme conditions, rendering the brake ineffective.
