Brake line Quick Disconnect

[Captain]

Has anyone had any experience with brake line quick connects?

I am looking to put one on the rear brake line. It drives me nuts disconnecting that line when I need to pull the motor on my 94 VD. (Which seems to happen one to many times mid season)

They look a little expensive, but to make my life a little easier, I want to give it a shot!

Thanks
Jim

There are many options for that.
I've been using these for my Vee for over 20 years..

but I recently found THIS - looks to be just as good but smaller

There is also the "official race versions" such as

as well as many other MORE expensive options. Just google 'hydraulic disconnect'.

Never had any problems with my "less expensive" versions, but then.. I DO drive a VEE

I have 'em. one started to leak after several years, replaced with one of Primus' units. Only leaked when disconnected, and that could be mitigated by raising the end above the MC reservoir.

Way, way, way easier to do maintenance!

Use Staubli QD's and you will have no problems at all. Not cheap at all though.
Used on Our FIA Formula E cars as standard equipment. Used on LMP1 cars, Indycars, GT cars, etc.

I've tried multiple brands (yes they are a great time saver, worth it and are on every car I've owned); the only ones that really seem work over time are the Staubli.

Runoffs and I can't remember what year or track but I do remember a SR that was sponsored by Staubli or maybe the guy owned the company. I had never seen the disconnects before but was intrigued because there was a set on every single fluid line on the car including each caliper !

I didn't see any leaks,.......... scratched my head and walked away.

Those Staubli ones are really nice. But wow, that price is a bit painful.

Great to know other people are doing something similar. One less headache is going to be nice!

I am going to research some of the cheaper option some more. The Jiffy brand ones seem to be a good compromise.

Thank you for the responses!

DO NOT CHEAP OUT ON THIS.
If it is out of your budget, then skip the QD's

That was Jeff Barrow who workedat Staubli at the time. Way before his time at HPD

Jiffy Tite is not the right product for that application! Will not handle the pressure.

I've used -3 Stabulis and whatever knockoff they sell at Motor State Distributing for brake lines. I've never had either leak while connected. I've had both slow drip when disconnected in certain circumstances. On the formula cars I mainly use them to facilitate splitting the car: I've got one on the clutch and one on the brake line near the bellhousing. When I re-assemble the car I don't need to bleed the system again.

I use Jiffy-tites -6 fittings on the fuel system for a combination fuel sample port and system drain.

In any case make sure whatever you're getting has the right seals for the application. Gasoline needs different seals (Viton, I think) than what's used for brake fluid or coolant.

If you disconnect dry breaks on brake / clutch lines try to avoid hitting the pedals when they're disconnected. Doing so will put unusual strain on the seals.

If you're using them on the fuel system, be wary of the dry breaks on the high-pressure side of an injected setup. They can still spurt fuel depending on the dry break design.

Also when you re-connect them make sure they're fully locked. I've had them pop loose otherwise.

Great description, Sam. I would add that my experience with the cheap ones in brake line applications is not so much that they leak, rather they suck air into the lines and I end up with a soft petal every session.
