Inline skates need regular maintenance to keep them working properly. If this maintenance has not been performed, then it may be time to repair them so they will once again be useful. According to Inlineskates.net there are three main areas to focus on when repairs are needed: Wheels, bearings, and brakes. All three areas will need to be addressed to ensure that the skates are rolling smoothly again.
Now that the skates are in good condition, it is a good idea to provide regular maintenance for them. Inlineskates.net recommends regular wheel rotation as they wear and regular bearing cleaning and lubrication. Once the brake starts to wear down close to the wear line, it is time to replace it.
