Gravity bleed clutch system - Does it work?
I finished up my TB/WP job today but made myself another. When I tried to reinstall the slave cylinder and pushrod I had a REAL hard time getting it to go back in, so, I opened the bleed valve and pushed the rodend until I could start the bolts.
well, I thought I snugged the bleeder, but later on I had a LOT of fluid in my catch bowl, and sure enough, the bleeder was loose, and the reservior was empty.
So, I refilled the reservior and cracked the bleeder again, and waited. I got a good flow after a couple minutes and so I closed and snugged the bleed port.
Well, as I said in my "so it ends" thread. When I started the car and thought to put it in gear for a little drive, the pedal went to the floor.
Is this going to take two people? Add more fluid and keep gravity bleeding? I'm screwed and now need to bleed the clutch master?

ok...you are not screwed but you're most efficient bet is use a power bleeder. I'm saying this because you let the resevoir run dry and who knows how much air is in the system. The two-man method may work fine, however your partner will most likely loose his leg in the process!! You seriously could be talking 3-4+ hours to bleed the clutch and most likely the rest of the brake lines just to be on the safe side.
- 1st - Try and get/make a power bleeder - Search for MOTIV on this forum and you will get all the help you will need. Also there check the DIY section of rennlist. There are some good tips there.
- Start with the slave and also have your partner push the clutch in at the same time to help bleed the master as well.
- Then start the bleed process with RR, RF,LR, LF process.
Good Luck -
YMMV, but I have also found letting the car sit for a couple of days will eventually clear up air bubbles..but whose got a couple of days!

huh.... my reservior is split and the brake system side never got low. I had a good brake pedal when I pushed it to turn off the dash light upon statup. You're saying I need to bleed the brakes too. Not a bad idea on a 22 yr old car, but do I have ta?

Start out by removing any preload on the master. That will ensure that the opening at the top is fully expused and open for air bubbles to pas through. Next, remember that air is lighter than brake fluid and the bleed screw is not the highest point in the slave. There are many ways to bleed the system and as Brad (from Ohio) said, the Power Bleeder is the biggest help.
There is a divider in the reservoir to prevent a clutch failure from taking out your brakes. If you're going through all this trouble and haven't changed your brake fluid recently, do it. If it's fairly new fluid, don't worry about the brakes.
