I have not used these, but I expect that they will work great. If I weren't in an economically challenged situation, I would buy them for every car I have.

I would suggest that when you use them, you open and bleed one caliper at a time.

Good luck,

Used mine a couple of weeks ago for the first time.. READ the instructions good. Check for leaks on that bleeder like it says. I ended up with a leak at the pressure guage. Didn't see it till I already was connected and had fluid in the container and under pressure. Had to take time to fix that. I pumped to about 18 to 20 lbs not being sure if I should go higher or not. Went to the right rear caliper and started bleeding, noticed the fluid coming out ok than slowed to a trickle it looked like it was not even moving. But in the end the old dirty fluid changed to clean fluid and continued on to the rest of the calipers and I ended up happy with clean fluid and NO brake pedal problems. Next year, if not sooner,it will be much easier.

Larry, dont you have a home made one that works great for you or was that someone else

I believe Larry is on the same page as mine. I am not sure about Early Bird. He is talking about a pressure gauge and I am not sure this is related to the speedbleeder I was talking about.

Earlybird - can you clarify what speedbleeder you are talking about?

Early Bird · #6 03-07-2003, 12:32 PM

Sorry about that. Maybe its the easybleeder, not sure now, but I have it. The plastic container, hand pump, and pressure guage to bleed breaks, and flush the fluid. I only need it to flush the fluid. Have I got to your page yet???

Ok I see it now, from that web site. The speedbleeders looks like the way to GO. As soon as I hear the word fluid and brakes easy bleeder comes to mine..........What do want its friday, my mine is shot from a weeks work.....hee hee hee

early bird:
the speedbleeders i am talking about are the ones you replace the original bleeders with. These would not require any other stuff - rather it will be a pedal bleed process.

thx

Yes, the speedbleeders are put in place of the bleeder fittings at the calipers. This is not a pump, vessel and gauge system. I have the Master Bleeder and it works okay, but you don't have a lot of pressure.

The speedbleeder fittings have a check valve. You put them on the caliper and when you loosen them the check valve allows fluid out when you step on the brake, but does not allow air back in when you release the brake.

After bleeding a wheel, you simply tighten the fitting and that wheel is bled. You are using good pressure to really blow the air and fluid out with a vengeance. The 20 or 30 PSI of the master bleeder works pretty good for flushing, but I have never used it for bleeding a system that has been seriously opened up for caliper repair or replacement.

Have a great day,

Bought 'em, but have not installed them yet.
I'll be sure to let everyone know how it goes.

Early Bird · #11 03-07-2003, 03:20 PM

Thanks for that explanation Larry Bible, I am now waiting for a user of that type of bleeding system to share the results..............

I am confident enough in the speedbleeders that if I had the money I would be them for ALL my cars at once without testing them on one car first.

Have a great day,

I've bought the speed bleeders for one of my autos (Taurus). It worked pretty well.

I just received my Master Bleeder the other day and will be testing it out for the first time tomorrow. I will be bleeding my clutch master and slave on the 240D.

Well, of course the economical way is to pull a lazy sibling/spouse out of the house for 5-10 minutes to pump the pedal...

But I noticed something that concerned me about the build-it-yourself pressure bleeder that someone was distributing plans for a while back

On the professional bleeders, there is a diaphragm between the fluid and the pressurized air. No Airation!

On the make-it-yourself (without a diaphragm) , I suspect you're airating the fluid when you pump up pressure (Even on a micro level that you may not see easily)

Bleeding is easy enough that you don't need alot of gadgets , if you're set on using a gadget-- use a hand held vacuum pump and a 1 man bleeder cup from autozone

note that there are more expensive stainless steel versions available in certain sizes. this is to address the issue of corrosion which would cause the check valve to fail.
