Replacing the Front Brake Pads on a Sym Bonus 110

Model: Sym Bonus 110
Part: Brake pads

Video tutorial

Today, I will show you how to replace the front brake pads on a Sym Bonus 110. First, unscrew the two bolts that secure the brake caliper to the disc. Next, use an Allen key to unscrew the two pins that hold the pads in place within the caliper.

This will free the pads, allowing you to remove them. Before inserting the new pads, slightly widen their seating, as they will obviously be thicker than the worn pads you have removed.

Proceed in reverse by first screwing in the two pins of the caliper and then mounting it back onto the disc.

Vespa Immobiliser: How to Transfer the Chip from the Old Key

In the case shown in the video, the new keys are not recognised by the ECU: the Vespa starts but does not run (thus the immobiliser is active). The solution shown in the video involves locating the immobiliser chip in the old key (the one recognised by the ECU). Open the cover on the key (only red master keys or some blue ones), remove the chip (which is a small black cylinder or rectangle), insert it into the new key in place of the new one, and try to start. Now the key will work. If the master key is red, it will definitely work. If it is blue, it might work: you need to cut the silicone; this is possible but a delicate operation. If it is a black clone key, then it is a system that does not work.
