I completely removed the stock cable from master cylinder to caliper bolted up new +2 cable, filled my master cylinder, pumped brakes, cracked open bleeder valve, pumped, cracked, etc etc until all air was removed and I had pressure just be sure to keep an eye on your master cylinder and don't let it get to low and start from your caliper farthest away from your master cylinder which is your left wheel unless yours is modified its tedious but can be done in 10 minutes or so if you have someone helping you to pump brake handle while you bleed them off
