Mine was about $50, very handy tool. It gets its pressure from a tire.

I only use about 5 pounds in my pressure bleeder. They will bleed with gravity so a lot of pressure isnt really needed. It seems pretty slick to use tire pressure, but does it limit the pressure or do you get the full 30 or so pounds?

It has a little adjustable regulator. I use around 15 lbs when doing brakes, I know it goes higher but cant recall how high, I think it goes up to 30psi.

The company is "Speedibleed". http://www.speedibleed.com/

Of course the price has gone up but its a slick little unit

That's very similar in concept to Gunson's Eezibleed, which is popular to the Britcar hobbists.

They tend to be cheaper, over there, anyway.

I am going to try the brake to clutch bleeding method today and I will report back on my failure in a while...

er I mean on my results.

I'm the optimistic type, if you can't tell

It worked for me- I drove it today.....

You do what I said with the small hose clamps and the pump, pump, pump, and dont be reporting back any failures

I do have a quick basic question. You are supposed to suck the fluid out of the clutch reservoir before starting, but how do you get at the part that is for the clutch? It seems to be divided off and I can't get in there.

Can you just suck it out of the part of the reservoir that is open and accessible directly under the cap?

Also I still don't understand why you actually have to suck any fluid out, especially if you are adding more in as it goes along (presumably because of replacing air taking up space in the system with fluid). Why suck fluid out at the beginning at all?

You dont have to suck any fluid out except when your done your resivour my be over filled when using the pressure bleeder. then just remove a little from the fwd chamber.

no results.

Same thing. Still won't go into gear while running.

I got my lady to help me and we pumped the breaks probably 15-20 times opening and closing the valve on the caliper. As far as I could tell I wasn't loosing much fluid from around the bleed screws. I could feel pressure build in the hose as she pushed down on the pedal, and then I would close the valve when she had the pedal down, and she'd let up.

I really had no idea how many times to pump or how I would know when it is done. That's not in the instructions anywhere, but I figured 15-20 would be enough.

Any further ideas?

It could of course be possible that something is actually wrong in the system...

It did suddenly stop working after all...

One thing I know is that the clutch pedal does push fluid through the system because when I bled from top down, I could see that the stream coming out the bottom would intensify when I pushed on the clutch pedal.

That only rules out a complete failure. Start replacing parts from the cheap end on up. Slave. Master.

Geeze, I give up

Can the slave cylinder typically be rebuilt? I found a rebuild kit for $20, it is just some rubber parts.
