Power Bleeder or what?
I think I have bled my brakes (manually) for the last time.
Does anyone have a good lead on a power bleeder or something that works better than beating the snot out of the brake pedal and my body? Thanks Don

I use a Motive power bleeder and love it. However, the homemade unit in the link above looks just as good and is only half the price.

R Leo & Roy:
Thanks for the replies and for the link (as I have most of that material already) Do you flush the homemade system with fuel or something so that the brake fluid doesn't eat it away? Don

I have a cap that fits my brake reservoir I put a air fitting on and I connect it to my compressor. I've used it several times by myself and it works great, even it I run it too long and blow air through the line.

I tried the Mityvac for bleeding and was never satisfied with it. |

Ditto on the Mityvac not working well. I seemed to get air coming into the system past the threads at the bleed nipple. It's hard to tell when you have all the air out of the brake system because of this.
whunter - I don't think Randy's home-made rig will corrode. He's just using it to pressurize the reservoir and it shouldn't come into contact with fluid (if I'm reading it right). I kind of like the compressor with a line to a fluid reservoir cap although I would cut the pressure regulator back to about 5 lbs or so. I vaguely remember seeing somewhere a brake bleeder that runs a line to one of the tires to obtain air pressure. Wes |

I dump a quart of fluid into the bleeder, screw the replacement reservoir cap onto the master cylinder and pump it all up. Basically, it recharges the reservoir as you go 'round and bleed the cylinders. Damn! It works great too! The only thing I can imagine being ever becoming a problem is the funky plastic tubing that runs from the tank to the cap. Everything else is poly. Of course, my contraption has been out at Greg's for a month or so, there's no telling what's happened to it or, if he can even find it!! I've gotta retrive it next week coz Scout's 240D needs a master cylinder. I'll report back on whether or not it has held up.

Shoot Randy...I'm betting Gregg has mixed up some high concentration Round Up and has been using it along the road.
Wonder how good Round Up works in place of brake fluid?

FYI
Warning: Over-stroking the master cylinder may cause it to fail.
This can happen to even the most experienced mechanic, "Especially" on a high mileage car. The old school manual brake pedal "down" - "up" - "down" - "up" bleed method risks over-stroking the master cylinder. The master cylinder piston seals can get scored if they're pushed into a normally unused - corroded, region of the master cylinder's bore. If this happens, you'll have little or no brake pedal, and will need a new master cylinder. I strongly recommend using a pressure bleeder to avoid the issue.
