Features:
Inserting a disc brake pad spacer when removing wheels prevents the hydraulic brake pads from closing together if the lever is squeezed, which would otherwise lock the brakes and prevent reinstallation. It acts as a substitute for the rotor, maintaining the correct gap and protecting the pistons from damage.
