Just finished bleeding the clutch slave cylinder on my 57 TR-3. I have a bleeder jar with a plastic tube and a hole in the top. Put your box end wrench on the bleeder valve, connect the tube, have someone in the car depress the clutch petal to the floor while you open the valve, close the valve, raise the clutch petal. Do this several times until all the air is out of the system, make sure you maintain the fluid level in the resovoir.
