The severity of the problem depends on external factors:

• do you live in a dry and salt-free environment? No problem.
• did the maker of your car implement disc wiping as a precaution? No problem.
• did the maker of your car implement intermittent brake blending during recuperation? No problem.
• is your car less driven in wet and salty conditions and then always store in a dry, warm garage? No problem.
• does your car have drumsin the rear and near-undersized discs in the front? Less of a problem.
