Wow Bill, sorry to hear that. I missed the earlier post. 

Most of what Allen said is pretty close to accurate. (bet he looked it up 
on the web ;-) One thing I learned from Reg. You can bleed the slave by 
just opening the bleeder screw a bit and putting your finger over the 
bleeder tip. Use your finger instead of using a wrench. In the close 
confines under the car that is sometimes a whale of a lot easier. Then 
tighten as normal, while the pedal is DOWN.

Good Luck

Larry
