over time, wear and tear gradually comes in, and for a person who consistently uses engine braking, this can speed that up.
Now, this may not apply to those who change their oil very regularly or religiously. But IMO it can happen. I know if you ask out there, you'll get a mixed crowd of people saying "it wont" and "it will". I was always taught that "it will". therefore, i like to keep it simple and use brakes for stopping and engine for moving. It's cheaper to replace brake pads than to overhaul an engine.
