CMH ‘Uniblock’ brake bleeding/maintenance system Sram YELLOW

Product Description

Two-in-one bleed and maintenance block, exposing the caliper pistons 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.

1. Install the block and pump the brake lever until the piston makes contact with the block.
2. You can remove the block and clean the piston.
3. SRAM advises not to apply any lube or grease to the pistons as this could cause them to stick. "Expose" the pistons and push them back 4 to 6 times.
4. On a 4-pistons caliper, push back the 2 pistons on the same side simultaneously or one after the other using the appropriate CMH tool.
5. Reinstall the block the other way round and repeat the process with the other piston. 

Compatible with Sram Code 4 pistons calipers.
