When bleeding the brakes have both brake calipers removed from the discs with a small clamp holding the slave piston in on one side. On the other side, hold the caliper up above the master cylinder with the piston and seal removed. Fill the master cylinder with brake fluid and slowly pump the brake. Be sure to keep the master cylinder topped up to prevent pumping air into the system. Pump the fluid up to the open cylinder until it is brimmed and no bubbles come out. Keeping the slave cylinder level insert the rubber brake seal in sideways and then rotate cup side in, trying to prevent air being trapped. Insert the steel piston and put a temporary clamp on it. Carry out the same procedure on the other side. It is helpful to tape some kitchen towel around the brake pipe to the calipers to catch any spills.

Later kits have bleed nipples fitted to the slave cylinders so ignore the above.
