Brake Bleeder tools

Anyone have any comments/experience with Brake bleeder tools? I continue to see the Mityvac Vacuum brake bleeder professional and home use, in other catalogs, but I don't seen any listed here on Pelican. I need to have the tool this week so more than likely will purchase at Trak Auto if they have them.

Thanks!

Go for a pressure bleeder. It's about $30 and was noted on this site previously. It simplifies the procedure and allows for a complete system flush. Only key is to securely clamp the vent hose at the MC to allow pressure buildup.

I'll second the motion for pressure bleeders!
I bought a Mityvac many years ago and have really only used it few times and have been quite unsatisfied with it. You have to make sure the seal is good at the bleeder screw, otherwise you just suck air in around it. I made a pressure bleeder taking design elements from several of the commercially available units and am HUGELY happy with it.
Its faster, cleaner and does a way better job than the Mityvac could ever dream of.

I bought a 'mighty whatever' vacuum bleeder and had absolutly no joy with it. The problem I had was that when I loosened the bleed nipples, air was getting sucked in through the threads and straight out through the tool - it looked like the brake system was still full of air.

I'm a fan of 'gravity' bleeding now. It takes a while, but is pretty relaxing and you can do it on your own without any special tools. If you're interested in gravity bleeding, check out the rennlist archives - there was a huge debate about it sometime ago.

mighty vac-waste of money. Bought the speed bleeders and they worked fine. Just didn't trust them and had a friend help me the old fashion way. Didn't improve over the speed bleeders so i would have to say that they actually work.

Dan--there a couple of pressure type bleeders
available. Mine uses compressed air from an external source like a tire or pressure tank
limited to about 15-20 lbs. It works great but the air supply is a minor problem. Saw a
real nifty model in AJ/USA's recent flyer that utilizes a pump up bottle like a garden sprayer that looks like the best idea yet. Check it out. Also--let me reiterate--CLAMP off the overflow hose first or your new fluid will end up on the deck around your left front wheel!

Dan,
I made a pressure bleed system by using an old hose off of a tire pump and a brake fluid cap from the junk yard, and use the spare tire pressure to bleed the system total cost $5.

Hmmm, got everything brakes here, including a pressure bleeder:

Thanks Wayne. I did a search under Brake Bleeding and got 0 hits and then I looked under the Porsche Tools category with no luck. I thought I looked under the Brakes section too but I must've missed the entry

Thanks

red911t knows. i've been doing it that way for ever. hang a foot long 50 cent hose on the bleeder nipple, open til it bleeds clean with no bubbles, and close the bleeder. it's the cat's ass!

I did a slight variation on the gravity method. I hooked up an empty pressure bleeder bottle and just pumped it up to about 5-7 psi. It helped to move the fluid a little quicker as I was flushing the lines, not just bleeding them. Worked great.

The Mity-Vac is a piece of schitt!
I bought a Motive Products pressure bleeder from Pelican, and it is great! So fast, clean, and easy. Well made too. It gives your brake pedal a real hard-on!

Funny that Mityvac gets all this bad press here. I've used one many, many times with great results, never had a problem at all.

I will agree, though, that a pressure bleeder is better (this is what I use now).
