Before I play some COD4 and pwn some noobs with the G3, I thought I would make this thread before I forget. In lieu of actually, finally, getting my brakes to work again tonight, I feel that the power bleeder I built a couple weeks ago helped.

What you will need(or what I used as pictured), I got all of this besides the cap at OSH:

Garden Sprayer/Weed Sprayer(11.99)
3/16 inch clear hose(2.99 for 8 feet)
male brass hose barb with threaded end on one side,3/16 inch(1.00)
accompanying nut for said barb(1.00)
washer for barb(free)
IMPORTANT: a Mazda 323 Master cylinder reservior cap!(freebie at junkyards)
-The stock Probe/Mx6 will not work as it will leak due to threads having gaps
Screwable C-Clamp for the cap(free)
Pressure gauge, threadable(11.99)

On sealants: I didn't use any, only on the cap and the brake fluid invariably just ate through it. So in essense, if you buy a thick enough Garden sprayer and undersize the drill bit for the barb for the cap, it should be air tight. I got it too 12-15 psi with no leaks. However, if you feel like you need it I would just go with JBWeld. Everything else may be eaten away by the brake fluid or may be too soft to seal like the blue RTV pictured(not backed by evidence though)



A lot of what is pictured I didn't use like the sealants, the two little C-Clamps, and inevitably the stock cap.

Drilled a hole for the gauge:



Gauge in, no sealant. Gauge threaded fine and seals itself against the thick sprayer walls. I would recommend using sealant though.



Hooking up the lines. Note: You may have to use different sized clear line if you use a different garden sprayer. You could size the hose up at the hardware store. There were displays I took apart at OSH to size the lines.



Cap, I used the pipe sealer pictured that ended up getting eating away by the fluid. Leak free though. Do not forget the C-Clamp for it when you put it on the Master Cylinder. It will leak other wise. Just tighten the Clamp around the cap and it should be good to go. Also there is a breather hole(WTF) in the cap that you will need to seal. I just used a screw I found in the garage.



All hooked together(this is with the stock leaky cap, but the pic works):



Again, this is with the leaky stock cap, but it shows how it all set up. I did not get pics with the 323 cap clamped on:




How to use it:

Just fill the sprayer with brake fluid(don't need that much maybe half of a bottle), attach the 323 cap to the MC and pump the sprayer to 10-15 psi as foretold by your gauge, do not go over these PSIs as you can blow the seals in your MC. Once you reach your PSI, crack the rear passenger bleeder screw. The pressure from the sprayer and in the MC will force fluid and air out. This took about 5-10 seconds for me to be clear. Move on to the driver front, then the rear driver, and lastly the passenger front. When finished use a turkey baster or a syringe to syphon out excess fluid from the reservior. Seriously will take you 10 minutes, if that, to bleed your brakes. I love this thing. Don't need anyone, and can be used for later use!

Also, I just built a catch can with the left over hoses fitted to a 1/4 inch hose and a empty water bottle. I should have gotten a picture of it, but it shouldn't be hard to make one, especially if you already made a pressure bleeder.

However, this does not work on the clutch slave. You will have to do it the old fashion way. Or atleast it would not work for me. Oh well.

hmm cool idea and application:tup: but isnt a pressure bleeder cheaper?... idk never priced one. but one thing i am wondering is there something smaller than a garden sprayer??? i mean that thing is HUGE! i will probably make one but heck i can see lending it to a friend and he fills the whole sprayer with fluid.. ehh 10 bottles should do it:)

Speed bleeders can run you from 20-40 for all 4. Granted they aren't as good as a pressure bleeder from what I have read. And they tend to leak. Vacuum and speed bleeding I have read aren't as easy and effective as a pressure bleeder. Though all three do work.

Looby, this is a pressure bleeder. And yes there are smaller garden sprayers. I didn't know what size I would need so I got the "middle" size. The smaller ones are definitely more than enough and cheaper to boot!

A pressure bleeder, like the one offered by Motive(probably the best bang for buck pressure bleeder) is 50-60 bucks. Plus the cap which is more money(or does it come with one, not sure). Anyways the cap they have for our systems is a universal one and I have read that exact cap leaks. A leaky cap will make the bleeder not work at all.

The hardest part of this build was getting/locating the cap. It seriously will take you like 20 minutes if that to build it.

Cool idea, inovative. I wouldnt even waste $ on that pressure gauge though.. Im sure a few pumps is plenty..Just watch for when it starts to build pressure

I try to make everything-to save money. I just made a steel locker/storage cabinet to sit on the side of my tool box. Everyone watched in disbelief, as I made it, Didnt cost me a penny and It actually looks pretty damn good.

King, I feel you do need a gauge. You would be suprised how many pumps you need in order to reach optimal(10-15)psi. You lose count lol. The gauge is needed too because you lose pressure everytime you crack the bleeder, so you need to be able to control pressure throughout the bleeding process. The gauge is cheap anyways.

Thanks! I was going to buy a Motive one, but found it faster and cheaper to just make one myself.

great stuff. I was considering how your fluid got to the top. But then I noticed it had a pick up line from the bottom of the container.

Yea the sprayer you buy should or will have a pick up line. The small black line that the clear line is connected to in one of the pics is the pick up line. On top of that the pump actually goes down to the bottom of the container as well.
