Using these rotors is straightforward. Just replace your old ones with these high - performance DBA rotors. Make sure to check the fit for your specific Mitsubishi Lancer model before installation. When it comes to maintenance, regularly inspect the rotors for signs of wear and tear like excessive grooves or cracks. Clean them occasionally with a brake - specific cleaner to keep them in good condition. Avoid sudden and extreme braking as much as possible, as it can put extra stress on the rotors and reduce their lifespan. If you notice any unusual noises or vibrations during braking, have the rotors checked by a professional.
