They are IF you bought quick-disconnect couplers that are of the sealing type.

For starters, none of this matters if you don't care to use the dry method. I personally don't want to spend my time ultra-cleaning my Power Bleeder after I am done with it, so I choose to use the dry method.

To prevent having to pump up the Power Bleeder each time you remove the cap at the hydraulic reservoir to refill it, the CPC quick-disconnect coupler with valve is placed within 6 inches of the cap. This maintains as much of the pressurized volume as possible.

I also used a quick-disconnect coupler with valve on the hose attached to the cap just so that I can release the pressure slowly. Not a must-do though.

Here is a valved coupler. Notice the part that protrudes beyond the coupler body in the upper right of the pic past the O-ring. You would press against that part with your thumb if you wanted to release the pressure.


It looks like you ordered the wrong parts or the supplier gave you the wrong parts. The part number needs that "D" in it for the coupler to be valved. I have those part numbers listed in my initial post.

Yes, repumping after each fill would be a bummer. After using the CPC parts set-up you detailed, I only had to pump the Motive Power Bleeder a couple times between fills and really probably didn't need to do that......was losing only 1psi or so between fills. At first I was worried I would need an additional clamp to ensure everything held pressure tight, but it was not an issue.

To do the whole system from dry I probably refilled the brake fluid 4 or 5 times using the dry method. It saved a bunch of time and pumping effort using the CPC parts and I don't beleive I spilled a drop of fluid anywhere......very clean.

Same experience here since I used it to bleed the clutch and brake circuits this week.

BTW, clutch action is as silent as a mouse now that a new clutch master and slave cylinder have been installed.

Alex, this is brilliant! I use the dry method, and I already have the Oetiker pliers. Looks like I will be ordering some valves!

I got my CPC valves from Controls for Automation in Taunton, MA.

The Oetiker stepless ear clamps were sourced locally at Fastenal.

valves ordered. This is the perfect opportunity to remove that heavy brass inline coupler on the original hose that i covered in tape so that it would not damage the paint work.

I did a similar thing by putting a schrader (tire stem) valve on a spare reservoir cap. A couple of pumps with a hand bike tire pump pressurizes the reservoir. You do have to re-pump when you open the cap to add more fluid, but parts were laying around the house.

Great article, Alex. I always enjoy your technical writing and pictures.

I'm doing the modification on my Motive Power brake bleeder now. FYI, it appears that the original tubing is about 0.3mm smaller ID than the 5/16 ID tubing from Lowe's. Motive Power has the original tubing available for 75 cents per foot.

Bobby, initially I used the same tubing that you also used from a local home build-it center. Its a vinyl tubing that is harder and as a result does not conform to the barbs on the Power Bleeder spigot, which isn't a great mold in the first place. It leaked there, even with a Oetiker clamp.

I contacted the owner of Motive Products and he got back to me with the type of tubing they use as well as the supplier. See post #21, one page back. My Power Bleeder is air-tight now.

BTW, the pics on my site still show vinyl hose without clamps being used. I now have the correct hose and an Oetiker clamp at each joint.

Nifty little tool, eh!

BobbyT

Yes, Alex, I use my bleeder on two of my cars, so only once a year on average, but it is nice to have it.

I also ordered some Oetiker clamps and a crimping tool.

Best always,
Bob

I came across Cole Palmer a few months ago. I ended up placing an order at Amazon.ca to get the items from them and ended up with free shipping.

Can you post the links? I just did a search on Amazon and didn't find anything...

I ordered a "CPC (Colder) PLCD22004" (one hose size smaller) and it came up on Amazon.ca with a Cole Palmer vendor. It was CA$16.05 (a tad more expensive) but shipping was free as I placed a $35 dollar order for other Amazon.ca items.

Could this work?
