Bleeding the brakes with a fresh fill is a whole lot easier with a plastic syringe. Typically, pumping with your foot takes far longer, and results in more foaming. In their master cylinder kit, CPP gives detailed directions for bleeding with a syringe, but here are the basics: There are two small holes in each circuit well, a take-up port and a pressure port. The take-up port is the closest to the firewall in each well. Start by injecting fluid in the take-up port until it begins bubbling out of the pressure port. This will effectively clear the line of any air.
