Can I use a different tool if I lose this spacer?
While some people improvise, using a dedicated bleed spacer ensures correct piston positioning and prevents potential damage to the caliper. It is highly recommended to use the genuine SHIMANO part for proper function and safety.

Troubleshooting
Spacer does not fit into the caliper.
Confirm that you have the correct spacer (Y2RB9802T) for the SHIMANO BR-M9220 caliper. Ensure no debris is present inside the caliper where the spacer should insert.
Brake pistons are difficult to push back after using the spacer.
Ensure the bleed spacer is fully seated and that no brake fluid has leaked onto the pistons. Refer to the SHIMANO service manual for proper piston retraction techniques. Make sure the spacer is clean and not obstructing the pistons.
Spacer was lost during maintenance.
A replacement genuine SHIMANO bleed spacer (Y2RB9802T) will need to be purchased. Consider using a small container or pouch for storage during future maintenance.
