I had the later one where the bug sprayer container forces air through the fluid which creates tiny bubbles in suspension. We had at Wayne's house the one that accepts air from a compressed air source. The only pain in using this is the reservoir is pretty small so that means many pauses in the process to unpressurize, refill, repressurize. I don't really see a need for this in regular brake bleeding since I always have the other person push on the brake pedal while I crack the nipple open. Once the pedal is to the floor, I close the nipple and then tell the person in the car to let the pedal up. On the last stroke, I will open and close very quickly to ensure that I close the nipple while the system is pressurized and that no air can get sucked back in from the nipple.

Two, I think: - Cap with quick-disconnect fitting (as seen here: http://www.ultimategarage.com/special1.html) - Cap w/gauge and regulator and quick-disconnect fitting (I have this one; doesn't appear to be available any more) Jim Bassett

Just like the brake pedal does only it uses air pressure at the master cylinder. It does NOT circulate air thru the brake lines - it uses it to create positive pressure above the fluid. Think inverted syphon... A few bubbles will occur in the master cylinder but don't sweat it they rise right out again unless you let the resivoir go empty. Notice that master cylinder always has a little room at the top... that is not filled with dark matter and its not a vacuum - its air. :) BTW, The BMW guys at the dealership I used to go to use a pressure bleeder. It has a cool adapter to cycle the ABS unit simultaneously and big Roundel logos on it but it's still a pressure bleeder. I'm no fluid-ologist either but I did sleep at a Holiday Inn last night. -- Walter

It installs in minutes, is easy to use, has lots of good data, including GPS and the ability to compare lines around the track. And then you can pull it from your car, put it in a friends, and do a back to back comparison. Price will be super reasonable, around the $1,000 range. More info later but I was super excited to find it and thought I would share now. I preach it all the time - there is nothing like data to really make you a better driver - spend the money on it now instead of the next go-fast goody and you will be way better off in the long run.

Think bad design. Since air is highly compressible these bubbles will appear small to the eye when in the high pressure reservoir. When depressurized in the brake system they will return to the volume that balances Boyle's Law (P*V=const). In other words: small volume, high pressure air bubbles equal large volume, atmospheric pressure bubbles. So the air bubbles change between small and large when you use the brakes and you have what's known as a SPONGY PEDAL. Again, basic Physics, not "Rocket Science". I'll second the Speed Bleeder option. I have them at the 4 corners, but not on the clutch. Note to self: buy Speed Bleeders for clutch. Best regards, Jeremy

Some of the earlier pressure bleeding systems based on bug sprayers had a single inlet system that was used for both the fluid pickup and the pressure inlet. Therefore when you pressurized the system, the dip tube (inlet tube) would "blow bubbles" through the fluid in the reservoir.

So I now use the devise to pressure bleed but use the devise dry, and watch the reservoir level, if I'm getting a lot of bubbles during a bleed. Otherwise I find the submersed valve issue a non-issue. -----Original Message----- From: Chester Wong [mailto:chester_p_wong@yahoo.com] Sent: Wednesday, April 20, 2005 3:26 PM <snip> I have the Steve D one collecting dust (if anyone wants to buy it off me, shoot me an e-mail). This particular one forces the air through the brake fluid to pressurize the container. I once experimented and allowed the fluid to go through to the cap and I looked at the fluid...lots of tiny bubbles suspended in the fluid from forcing it through the fluid.

It's one of those while-you're-in-there type of things. They are rubber and do tend to stretch and break over time, so easy to replace with new ones when doing an exhaust. > can anyone clarify which parts exactly > (part #s would be great for 1997 M3 ;)) According to RealOEM.com (hint hint :-)): 18201401797 - you'll need two. > i should replace when i do the > exhaust change? anything else while i'm in there?
