How do you bleed brakes after installing new brake lines?
You connect the tubing from the vacuum pump to the brake bleed screw via the tubing provided in the kit. You open the bleed valve and pull the fluid from the reservoir down to the brake caliper with a few pumps. The trick is to be sure you keep the fluid level in the reservoir high enough.
