I just finished bleeding the brakes on the '40 today, and used a Motive Products bleeder. It worked great. Simple, reasonably priced and effective. The only drawback is Motive Products didn't have, was out of or didn't know what adapter fit the 1050 MC in the '40, so i had to make my own. I drilled and tapped the MC cap for 1/8 NPT, temporarily plugged the 2 small vent holes with epoxy and made up a detachable hose connection to go between the MC cap and bleeder hose. The photos will show the MC cap with the 1/8 NPT x 1/4 brass nipple, the supplied slick crimp bands, 1/4 clear vinyl hose and 1/4" SAE female swivel nut that mates to a male SAE 45 degree x 1/4 NPT adapter that threads into the Motive bleeder hose fitting. Anyone have the part # for the Motive adapter that fits the 1050 Ford MC ?

Russ.....

That's exactly what I did. I had the same cap....bought a fitting....tapped it out and my buddy brazed the 2 air holes and also brazed the fitting to the cap and I used the Motive pressure tank. Worked like a charm !! I pumped it to 15psi and it held pressure so I know I had a closed system. When I opened the bleeder valve there was a blast of air that shot out and then a good fluid stream. The fitting I made up worked great. It's such a relief after 8 months of screwing with it. Life is good again !

Thx....Mike

Hi Mike

Did you drill out the 2 vent holes afterward ? I plan to, that's why I was looking for the correct adapter. I have an email into CS at Motive about figuring out what adapter fits the MC. I offered to send them the MC cap, but CS says they need the "reservoir", which gives you and indication how far out in left field CS is. I sent them pictures of the MC cap, it's threads, and the MC top opening threads. I also told them the 1050 MC was the "reservoir". Will see what they come up with. If you had a Honda they would know exactly what you needed.

Russ.....No .....I saved that one I made up just in case I have a prob in the future. I had a couple extra caps and used one of them. There is NO adapter available for the old cars and that's why I went with what I did. Works great. I left the small holes brazed shut.

That's good to know because if there are no adapters for older cars I will find another cap for the MC, and keep this one as is for the same reason.

Curious, you fellows who used the pressure bleeder, did you use DOT5 silicone fluid?
I ask, because i hear it said frequently, that you must not agitate DOT5 because it causes micro bubbles and contributes to a spongy peddle.

tubman · 06-07-2021, 10:59 AM

DOT-5 fluid is on the way out. It does not work well with anti-lock brakes, which are becoming more and more common, so it will become increasingly difficult to source. Also, as you stated, it can be hard to bleed. I had it in my '68 Corvette. It was very difficult to bleed, but once I got it in, it was great. That being said, it was the last time I used it. I now flush and change the fluid in my cars brake systems every 10-15 years with no problems. Speed-Bleeders make this an easy process.

mike42 · 06-07-2021, 01:37 PM

Russ and Russ '40.....save the fitting you made as there is NO others available. I talked with the Motive guys 2 times.

I am using DOT 3 and never tried anything else. Brakes good right now, but had a fuel prob of late that I'm working on.

Thx...Mike

Damn! When it GO's, it won't STOP! Then when it STOPS, it won't GO! Then, when it ALL works, there's too much snow to play, right? DD

On the subject of adaptor caps for oddball cylinders.. You don't actually need a screw fitting cap. I have used a flat piece of plate with a npt hole drilled and tapped in it. I positioned the plate over the hole using a piece of rubber cut from an inner tube and clamped the plate to the top of the master cylinder.
Once fitted, just proceed as normal with the pressure bleed operation. As they say: "It worked for me".

mike42 · 06-08-2021, 08:05 AM

Coopman ...you are right. Snow comes fast in Northern Michigan in late October !! Get done what you can when the Sun is shinning !

Mart.....I bought that kit from Motive with the flat rubber plate and the chains and screws, etc. I threw it in the trash. Could not get it to seal properly, but maybe that's just me. I made up the plug from an extra cap I had and the "first" time I used that pressure bleeder....."instant" hard pedal !

Thx.....Mike

Do you know the issue of the ford v8 magazine that has an article on spongy 1940 ford brakes on page 95? Thanks for your help.

Zeke3 · 07-26-2021, 09:04 AM

Volume 58, number 3, May/June 2021 Early V8 Times has an article about suspect brake parts on page 95.

19Fordy · 07-26-2021, 09:17 AM

I wonder if you could make a custom MC bleeder cap using a rubber freeze plug?

Vet & Zeke ……. I did see that article and torn down one rear and one front to check measurements and all okay. The new shoes were exactly like the 1940 original Ford shoes.

Fordy ……..you might be able to do that, but I happened to have an extra steel cap and had a buddy braze on a fitting. I’ve got 400 miles on the brakes now and I just re-bled & I’m in great shape with brakes !

Thx……..Mike
