This method worked WAY better than I would have first guessed.
Parts/tools: Brake fluid 2 liter plastic soda bottle (flushed with water and then a bit of brake fluid) rubber grommet or silicone sealer 2-2.5feet rubber hose (sufficient size to fit the slave bleeder valve) drill a couple of rags to mop up brake fluid I had just replaced my master cylinder and was having no success bleeding the system. No parts store in this area had a pressurization kit of any sort and I couldn't wait for and online order. So... I grabbed a 2 l. soda bottle. - drilled the top - fit a rubber grommet (although I was ready to use silicone sealer if I couldn't find my stash of grommets - fed about an inch of the tube through the very tight grommet - Flushed the bottle with hot water and then a but of brake fluid Filling the bottle with 2-3inches of brake fluid, I turned it upside down and let the fluid fill the hose. Attached the hose to the bleeder valve and opened the valve. Initially, I tried to squeeze the bottle to force the fluid in thus dispelling air into the brake reservoir. No luck. So I did the easy thing. Set the bottle upside-down in the engine bay with enough fluid to cover the tube by at least 2 inches. Then pumped the clutch. I could see fluid moving within the bottle, air bubbles and eventually just fluid. With each pump of the clutch, it would push out a bit of air and fluid then suck in more fluid from the bottle and reservoir. I had to partially fill the reservoir twice. The clutch regained a solid feel in much less than 5 minutes. Tighten the bleeder valve, pull the hose and a few more pumps on the clutch. Note I had started the car previously to regain a vacuum after having disconnected the vacuum booster during install of the cylinder. I hope this helps. wsaabi |

I used a hand pump-action garden sprayer.

a friend of mine uses a length of pipe between the clutch blead nipple and the lh front brake blead nipple losens them both and pumps the brake, the fluid from the brake bleads into the clutch and bingo a nice firm clutch
