Using this AS3 front brake disc is straightforward. Just install it on your 2004 - 2015 Husqvarna TC 85 (Small Wheel 17/14) following the standard brake disc installation process. For the best braking performance, it's a good idea to use AS3 Performance brake pads as recommended. When it comes to maintenance, regularly check the ventilation slots to make sure they're clean. Dirt and debris can block these slots and affect the disc's cooling ability. You can use a soft brush to clean them. Also, keep an eye on the overall wear of the disc. If you notice excessive wear, it might be time to replace it. This brake disc comes with a 12 - month warranty, so if you have any issues during this period, contact the manufacturer.
