I tried using my Motive pressure bleeder with the 1107 Ford 3-prong adapter to bleed my G35 brakes. But for some reason the 1107 adapter is not holding pressure. I pumped to 10psi and air would leak out completely in about 3 mins. I made sure the cap was on all the way and there is nothing between the M/C and the cap. Has anyone experienced the same? I see several people here and on my350z are using the 1107 adapter, are you not having any leaks at all? I can hear a loud hissing noise as soon as I go beyond 5psi. Is my cap defective?

I have had the Motive bleeder for my Miata for many years. For that car I used the J-hook adapter and I never had any issues. I really think the 1107 3-prong cap is not strong enough to hold 15 psi.

Thanks.

No issues here. You are pushing the cap the turning it to lock it in place correct? The top of the bleeder is secure as well?

 

Yep, the cap was pressed in all the way and it was straight. I tried to turn it further to tighten it but it became loose and kept spinning. So I gave up on the 1107 and went back to my old 1101 J-Hook adapter.

The 1101 worked fine and held pressure for the whole day so I was able to check for leaks in my Stoptech brake system. I positioned the chain under the metal master cylinder, in front of the sensor wire and behind the hard brake line. I also made sure the cap was centered for a good seal. It worked perfectly and was very easy.

Personally I would say don't bother with the 1107 and just go with 1101. 1101 is a universal adapter and will work on many cars, so it's a better investment. I wish I didn't waste time and money getting the 1107 adapter.

 

Works fine with the ford adapter on my g sedan.
