LIMITED PRODUCT DROP: The Ultimate Bleed Block For Your Disc Brakes —perfect for cleaning caliper pistons and bleeding brakes.

Description

One brake block to do all the maintenance tasks on a brake disc caliper. Bleed and piston exposure all wrapped up into one versatile tool. Loads from the top of the caliper and keeps itself in place - no need for the pad retainer pin unless you flip the caliper upside down. This makes service faster and easier.

Use

For bleeding, leave the filler block in place. For piston exposure, flip out the filler, put the block into the caliper, and pump the brake until the piston stops against the step. The filler block is tethered to the main block so you don't have to worry about losing it.

Important: We recommend, for Shimano, using alcohol to clean the piston and following up with mineral oil on the side before pushing it back in with the CMH Piston Spreader.

For 4-piston calipers, push back both pistons on one side either together or one at a time using the CMH Piston Spreader. Flip the block, reinstall it, and repeat the process for the opposite side.
