K5 GSXR 600 Front Brake Bleed Block

Block to hold your front caliper pistons in while you bleed or flush your brake system. Should be the correct size to fit tightly into the caliper with the pistons pushed all the way in. If it's too tight you can shrink it slightly in your slicer. I put the hole in it to have a place to stick a screwdriver to pry it out when finished bleeding.
