The block is a two-in-one bleed and service block, allowing the caliper pistons to be exposed for cleaning.
This is a block similar to the bleed block, but with one side stepped, so that when you "pump" the brake lever, the piston is allowed out but is stopped before it exits the caliper.
Install the block and pump the brake lever until the piston makes contact with the block.
You can remove the block and clean the piston with alcohol, then apply a little mineral oil to the side and push the piston back in using the appropriate CMH tool..
Reinstall the block the other way round and repeat the process to clean and lubricate the other piston.
Unlike the yellow Shimano blocks, the CMH bleed blocks are inserted from the top, they are easier to install and do not risk falling during bleeding.
