CMH Shimano RED Brake Bleed / Maintenance Blocks (G or J pads)

Product Description

The kit includes a bleed block and a maintenance block to expose the caliper pistons for cleaning and lube.

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.

1. Install the maintenance block and pump the brake lever until the piston makes contact with the block.
2. 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.
3. 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.

Compatible with calipers using G or J type pads.
