Phoenix System Brake Bleeder...............Will it bleed a system when the master cylinder is located beneath the floor and below the level of the 4 bleeder screws? The theory seem okay on a conventional firewall mounted master cylinder but I question if it will do our street rods with below floor m.c. setups. Hate spending money on something that might not work. I used Speed Bleeders on my last build and they worked okay but this is something unknown to me.
