Mate you need to unbolt the rear caliper in order to obtain a hose line more conducive of bubble travel. Unbolt it and let it hang and then there's no chance bubbles will get stuck in the caliper or the line. As it is, you're pushing the fluid across the caliper, then the issue is the fluid moving DOWN the line before it travels up to the leaver. Unbolt the caliper, always.
Hey, I appreciate your suggestion and the reason behind it. However, this video was not an instructional video for how to bleed brakes, so following the SRAM service guide is more than appropriate.
