Brooklyn has dealers and shops where one can buy bus parts and supplies. Like any other machinery with moving parts, the bus parts are subject to wear and tear due to use. It is important to get them checked and replaced when wear and tear is noticed, to ensure safety and optimum functionality. These supplies, available in Brooklyn, include high-quality OEM, aftermarket and private label components for most popular coach, transit, and heavy-equipment models. School bus supplies are commonly available. Such parts usually come with a warranty and quality assurance. Some of the parts that may be made available (a catalog or an inventory list would be usually made available to pick the parts one needs) include alternators and starters, brake and body parts, decals, cold weather accessories, flashers, relays, monitors, heaters and defrosters, lamps and lights, seatbelts, safety equipment, sound systems, suspension, wiper parts and many more.
