Uh, brake cleaner is meant for metal brake parts, not rubber. Not at all a good idea to spray it all over the caliper with the piston still in it. It likely damaged the piston seal. I would have removed the piston, cleaned it up, cleaned the bore up, replaced the rubber seal on the piston, then lube the piston and bore with clean brake fluid, and reinstall the piston. Once that's all done. I would loosen or remove the bleeder screw, tie something to the caliper and then to a chair or something to hold it away from the scooter to keep brake fluid off it, remove the master cylinder cover, and fill the master cylinder with fluid. You will notice fluid dripping out of the bleeder screw or screw hole. You don't need to do anything but wait. The system will gravity bleed itself. Pour about a pint of new brake fluid through the system, and before the master cylinder runs empty, install/tighten the bleeder screw. It's a good idea to loosen and tighten the bleeder screw with a socket. An open end wrench tends to crush them. Top off the master cylinder if necessary, and reinstall the cap. The system is now bled. No vacuum bleeder or 2 people needed. Works on anything that does not have ABS. Please cut those zip ties and remove that horrible looking reflector.

The best video in the perfect timing. Thank you
Great video! The tip on poking holes in the brake fluid container is very neat.
