The Shimano Disc Brake Caliper Bleeding Spacers are incredibly useful. They hold the pistons in place when you remove the pads for bleeding, making the bleeding process efficient and accurate. This feature ensures a smooth and effective brake caliper bleeding operation.

Using this spacer is easy. First, remove the brake pads from the caliper. Then, insert the spacer to keep the pistons in the right position. This will help you bleed the caliper properly. When you're done, take out the spacer and put the pads back. Make sure to handle the spacer gently to avoid any damage. Keep it clean and store it in a dry place. If it gets dirty, you can wipe it with a clean cloth. This way, it will serve you well for a long time.
