Here are some of the maintenance methods we’ve received from the Webike Community "MOTO HACK Maintenance" campaign that we’d like to refer to. Maybe you have an idea you'd like to try!
In this article, I'm going to introduce the maintenance HACK from Webi-man who rides ZRX1100.
Motorcycle introduction and its maintenance

Working hours
About 3 hours.
Working difficulty
Simple
Items to use

Learn more about the work
1. Release the two bolts holding the brake caliper in place and remove the brake caliper.
*There are a total of three brake calipers on the ZRX1100, but you can start from anywhere. This time I started from the front left side.
*Work on a platform at an appropriate height to avoid putting pressure on the brake hoses.
2. Pull out the brake caliper pad pins and remove the brake pads and pad springs.
*Clean the pad pins and springs with parts cleaner. The pads are cleaned with a neutral detergent.
3. Squeeze the brake lever to push the piston out.
*Be careful not to grip the lever too many times as the piston will come out too much.
4. Clean the brake calipers with a neutral detergent.
5. Air blowing drains the brake calipers and dries them out.
6. Spray the piston with metal rubber and wait until the bubbling is cured.
*You only need a small amount to spray.
7. Operate the brake lever to push the piston out and then repeat the process of pushing the piston back in as it comes out.
*The rubbing out process is performed on all pistons.
8. Push back all the pistons and wipe off any remaining metal rubber.
9. Assemble the brake pads by applying a thin layer of pad grease to the back of the brake pads and a thin layer of molybdenum grease to the pad pins.
10. Clean the brake discs with parts cleaner before installing the brake calipers.
*Clean the holes as well as the surface.
11. Install the brake calipers and tighten to the specified torque. After this, work the same way on the front right side and rear brake calipers.
Points of caution and tips for work
When removing the brake caliper, be careful not to damage it by hitting the wheel. Also, be careful not to damage the brake discs. If you have a front double disc model, I would recommend removing the brake calipers one at a time, even if it's a hassle, and working on one side at a time. I have had a situation where I have concentrated on rubbing out one side and caused the piston on the other side to fall out. Also, be careful not to put too much pressure on the brake hoses when cleaning and rubbing them out. I've heard it's best not to use parts cleaner on the surfaces of the brake pads that contact the discs, so I think it's best to use a rag to remove the pad grease on the backside of the pads and wash the surfaces with water. When removing the brake pads from the rear brake caliper of the ZRX1100, be careful not to lose the pad pins, as they may pop out.
Advice
This work has improved the brake caliper movement. I think it's a good idea to do this periodically. It's a relatively simple task, but needless to say, the brake relationship is an important part of stopping the bike, and it can be dangerous if it's faulty, so if you do the same thing, do it at your own risk. If you're in doubt about whether you can do it, it's best to leave it to the professionals.
Thank you, Webi man, for posting this valuable maintenance HACK! You will receive 1,500 points to be used at Webike!
