[HEI451]

I use the "tilt the master ON the vehicle" method, it is the only way it works for me. It is as yo did above, mounted the master on the vehicle, connected the lines, removed the master from the booster/firewall, tilted it forward to get the bleed ports in the reservoir to their highest point, and watched the bubbles come out as I gently pump the push rod.

Of course, I've always been told I was an idiot, moron, half wit and other expressions of mis-knowledge when ever I outline the "tilt the master" method, including a topic right here, not a week ago, but, this method has NEVER NOT worked for me, NEVER. IN fact, it is the ONLY way to get Dot 5 fluids to bleed in a motorcycle system without getting the fluid aerated.

The main problems with the hose bench bleeding method is, when the hoses are removed to remount the master, the ports are opened back up to atmosphere, and AIR re-enters the piston/cylinder area, causing a loss of prime, and, the master will always be set level in the vise, which doesn't allow all the air to bleed from the piston/cylinder area through the bleed port(s). Tilting the master so the bleed port(s) are at the highest point, and then bleeding the air out via the bleed port, is the only sure fire way to get all the air out of the system.
