Trickstuff Le Block Universal Bleedblock

The Le Block Bleedblock is a simple, anodised aluminium cuboid that is compatible with most common disc brakes. Inserted into the pad shaft of the brake calliper, in place of the brake pads, it prevents brake fluid or oil from spilling into the pads, while anchoring the brake calliper.

Unlike bleedblocks made of plastic, it's rigid enough to help you reliably judge whether the brake is free from air and discover the perfect pressure point.
