you wont wear out the brakes any sooner by not using reverse thrust.
About 30 years ago an article was published by the brake manufacturer of the brakes on the DC9 titled "The High Cost of Hard Braking" It tabulated in dollar terms the relative costs of braking at various speeds versus reverse thrust from idle reverse to full reverse.
I'll try and locate the article but the conclusion was crystal clear. With idle reverse the cost of brake wear and tear were almost doubled. Of course these were not carbon brakes. But I find it difficult to understand that pilots who advocate idle reverse and significant braking are seemingly oblivious of the potential dangers associated with hot brakes. I recall an old Boeing bulletin stating if you could not place your hand on the brake units then by definition the brakes were hot and appropriate delays required.
