There are two questions you need to ask yourself:
- Are your brakes "fading" during the descent? That is: do you have to pull the lever harder and harder to achieve the same amount of deceleration?
- Is the rim getting hot enough to melt the tire rubber or to cause the air in the inner tube to expand to the point where the tube and tire will rupture?
If you're not experiencing either of these problems, you shouldn't have anything to worry about...
