Best One Man Bleeder System

[andrewb70]

Whichever method you choose remember that bleeding brakes is not about force, or pressure. It's about volume. Many people forget the ultimate goal; to rid the system of air. Any air that is in the system needs to be replaced with fluid. It is just that simple. If you have patience a gravity method works quite well. I've used that method on particularly stubborn systems. Air is lighter than brake fluid so it will want to travel to the highest point in the system. You just have to provide a clear path and replenish the lost volume with fluid.

Yes, the Motive product will work with Wilwood. The only thing I found is that you want to keep the pressure around 5 psi when using the plastic remote reservoirs, otherwise the pressure can push brake fluid past the O-ring.

John,
I have the tandem aluminum Wilwood master. Do you know offhand which adapter works with this master? Thanks.

[rickpaw]

The Motive adapter for GM cars (flat type) will not fit the tandem Wilwood master. The master is a tad too long. Gort69 (Al) and I tried to bleed my 67 FB and it did not fit. I ended up buying the same kit from Harbor Freight as Larry's, and it worked fine.

No, I don't. I've done my Z06 and Wilwood remote reservoirs. I've never bled a Wilwood tandem master.

Thanks for the info. As much as I would like one, I don't have an air compressor, so I'm looking for something that's self-contained.

Nick - If I'm understanding correctly, you are thinking that the Motive bleeder uses an air compessor? If so, not so! It's basically a garden sprayer with its own hand pump and a pressure gauge. If I misunderstood, please disregard.

[aronhk_md]

Garden sprayer......hmmm.....excellent idea. What about using a small garden sprayer and just going in reverse? Sounds a lot like Larry was suggesting from Harbor Freight, except you'd use it without an air compressor. The thing I like about going in reverse is all bleeders are essentially the same. No need to buy various fittings for various cars, or wonder if the one you are buying is gonna fit.

My big question is......is filling in a forward direction any better than filling from down below?

My initial thought is it would be better actually, as air will rise in the system. But I'm guessing the answer is more complex because I dont know the mechanics of the average proportioning valve and master cylinder (beyond basics).

Still, from whats out there on the market for the purpose....I believe reverse filling is an accepted way correct? My only guess is that it wont work with my speed bleeders. I'd need regular bleeding valves (which are still in my toolbox).

Just ordered my motive bleeder today based on this thread.

Believe it or not but I was shocked at how well this worked from Harbor freight. I used it for my brakes a few times and my clutch.

Toss the smaller bottle in the trash, hook up the large one to your bleeder screw and feed it 90psi or air.

Same one I bought. Works phenomenal for $25 , waaaay cheaper then the Vacula or other one's.

[SIZE="3"]Larry,

So that system from Harbor Freight handles 90 psi ok? Also, since you are pushing fluid in the reverse direction, do you still need to bench bleed the master cylinder? Will I need to remove my speed bleeders to do this?

Yes.

As for bench bleeding the master.........can ANYONE explain to me how you get the master cylinder in place, remove the nipples and get your brake lines in place without getting fluid everywhere?

Most new master cylinders come with screw in plastic caps into the 2 fittings.
If you don't have them, maybe the auto parts stores carry them.
Raybestos new 79 Vette disc/disc masters came with them.
The repop Autozone one's came with the tube style caps.

I bench bled my 2 masters angled DOWN in a vise for both my cars
Caps in place, and keep pumping it until it the piston won't move anymore and no more bubbles coming out.

I have always used the vacumn style-always worked great.

[67cougnut]

+1....I use this in combination with Russle's Speed bleeders and that worked great for me.

+2 on russell speed bleeds i have even used the motormite "help" ones with positive results.

What's the 'best' way to bleed brakes by yourself? I'm sure there is some personal preference when it comes to what you like, just looking for suggestions. This will be for occasional garage use, not daily by any means.
Thanks,
Nick

Not sure about the best, but for personal preference I can say.

I like the speed bleeders (bleeder valves on the calipers).

I have tried the vacuum pumps at the calipers, works great. The pressurized MC cap, works great. The old fashioned way (wife pumping the brakes while I crack the bleeder) always works.

But the speed bleeders were the latest method for me. And I really like them. With the cap pressurized systems and the vacuum systems they are great for a quick fill of a dry system, like you just put in all new brake lines and calipers. They move alot of fluid fast and get that part of the job done.

But..... I have followed up the bleeding process with those after I thought all the air bubbles were removed just for a check. I used the speed bleeders cause the wife was pretty much done with my constant use of her right foot

The speed bleeders put a whole LOT more pressure through the lines, fittings and calipers. The pressurized or vacuum systems put ALOT of volume, but not much pressure compared to what the brake pedal will put out.

And sure as sh*t, I got some small bubbles. And yes, I was pushing hard and fast on the pedal. Just to try and dislodge any small pockets of air with some turbulence. And I did.

Not large bubbles, but more of a tightly packed section or two of small bubbles. Almost looking like a small section of foam the bubbles were so small. But they were there (in the clear 3/16" ID tube I used for a drain from the bleeder), lodged in a tight crevice or pocket of some component (prolly the caliper) Im thinking.

And this was looking at the tube, filled solid with fluid after some moderate pedal pumps before I got more aggressive with the pumps. I got more aggressive because I wanted to make sure there wasnt any trapped air. So I pumped the pedal a few times normal, just to get the fluid flowing into the drain tube an fill it. Then hit it with ALOT of pressure. Thats when the additional air bubbles broke loose and vented out.

The thing is, I think there will always be the slightest amount of air pockets in any system. Calipers arent designed perfectly, they will still have high areas and very small voids that the air can get trapped in.

My thinking was if I could create enough turbulence within the caliper with a large inflow of fluid maybe I could force the fluid into those pockets and drive some of the air out. And IMO I did.

And you wont get that turbulence unless there is a high pressure AND volume of fluid flow. Only way to get that is with the pedal and an open bleeder valve.

So employ the wife, girlfriend or buddy to monitor the bleeder to close it off for every pedal push. Or get some speed bleeders.

The speed bleeders act very fast too. I was able to monitor two of the clear drain lines while pumping. And they dont let any return fluid. And really, I was hammering the pedal, pushing really hard and just letting it come back up then hitting it again. There wasnt any back flow at all and I could watch the column of tiny bubbles march on down the drain tube.

I dont know why I waited so long to install these lil valves. Maybe cause I was old school and had some reservations. No more. Im sold.

And my brake pedal is tight, right at the top with the first push. I have power brakes. But with the engine off the pedal is right there, there is no air in the system.

Oh and yeah, the 62 Nova stops on a dime, sure the 13" discs help.

But for a super simple one person bleeding op the speed bleeders are the ticket. JR

Thought I would resurrect this thread... I purchased the Motive bleeder and finally got ready to use it a couple of days ago. The guys were correct, this is a NICE system to use for bleeding your brakes. I did not bench bleed my M/C and gave it a try. Once everything was hooked up I had a solid brake pedal in 15 min.
My good friend Charlie warned me to be careful when removing the cap as the M/C will be full of fluid. I purchased the large billet cap they offer, put two 1/8" pipe thread holes for each resv and plugged them. When done, I use a syringe to pull some fluid out before pulling the cover off the M/C. Glad I was warned... I would have had fluid dripping on my freshly painted chassis!

Overall great product.

Fuelie,

In the directions for the motive bleeder it says that if you still have fluid in your motive bottle, it says to move the bottle into a position where the pickup hose is no longer submerged in brake fluid. If you open the bleeder closest to you, the system will pump air through the hose and into the master pushing the fluid level in your master down so you don't have to worry about the big mess. Then you can remove the cap on the master and either remove or add extra fluid to the max fill line. Of course your method works too.

[THE TECH]

I've bought just about all types out there. My favorite is the Phoenix system. The Motive is good for newer vehicles but that chain and rubber cap thing is a pain and doesn't really work with all m/c setups.

[gsxrken]

Didn't read the whole thread so forgive me if this was said. I use the Motive pressure system "dry". I fill the master, place the motive cap on it, and pump in about 15PSI of air with the charging handle. Then I go to each caliper and crack the bleeder until it runs clear. Then next corner.

Much easier to clean up, and no disaster spill possibility. You do need to keep an eye on the fluid level in the MC just like typical bleeding. As a one man show, it can't be beat.

Garden sprayer......hmmm.....excellent idea. What about using a small garden sprayer and just going in reverse?).

I agree and have been there done it. I wanted to not have to ask her again so I went with the speed bleeders. Works like a charm.

And I have tried every type of brake bleeding there is. The speed bleeder valves are the best so far. Talk about easy.. JR
