FAQ

Frequently Asked Questions

When to replace brake disc?

If disc thickness reaches wear limit (e.g. 26→24 mm), DTV > 0.02 mm, or visible heat cracks. Replace immediately on any.

Vented vs solid disc?

Vented disc has center cooling vanes, ~30% better continuous-brake cooling. Solid is simpler, suited to light duty.
