Default beringer brake lines fueslage

I have run into much difficulty matching what is in the Beringer install/maintenance manual vice vans install.

I am now trying to route the brake lines back to the drag brace fitting from the master cylinders and I notice the thread pattern for the vans 7/16 pipe coming out of the drag fitting and the Beringer 7/16 fitting do not match thread types. The vans is a fine thread versus coarse for the Beringer fitting.

Anybody else notice this?

Larry

I had TS/AS Flightlines do all my lines fittings - they did all the adapters/fittings. If you give them a call, I imagine they can tell you what's needed to make it all work.

Larry---the ports on the Matco/Grove/Cleveland master cylinders are 1/8 NPT tapered thread. Beringer uses M10x1.0 Metric parallel thread with a crush washer. THESE ARE NOT INTERCHANGEBLE. The Vans original plastic lines and fitting are not used with the Beringer components!

Roger that.
I have fabricated the Beringer brake lines per the manual and had no issue with the master cylinder. It is the long output hose from the left hand output side back to the original fitings on the drag brace( installed two years ago) that is not compatible with what Beringer sent me. The 7/16 adapter fitting supplied is a coarse thread. The fitting installed is a medium or fine thread. You get one turn and that's it.( mis thread). You can see it pretty easy with the naked eye.

I am gonna call you guys to fix the issue. It is Beringers mistake...again. There have been many I have sent back to them with the help of my French engineer friend. Its a slow process to get resolution.

Larry and others, you cant use the Vans Brass adapters in the gear mount with AN style hose ends. The Thread on the brass fitting where the AN nut would screw on is different, AND no male flare. You have to use compatible fittings for the type of hoses you use.

Beringer 2.0

Today I had my French engineer friend call France via an appointment that was set up last week. What we found out is the source document Beringer was using to design the brake line kit for the rv14a was based on section 40 of the manual which indicated larger fittings (4D) than reality(3D) into the gear brace.

The Beringer engineering solution was to omit the fitting in the brace and simply have a longer hose pass through the brace to the caliper. This essentially eliminates a fitting. They are of the opinion that the less the fittings the better.
The new hose will be 132" from cylinders to calipers.

They are in the process of making this change in France.

Bonsoir
Larry

Default beringer brake lines Pilot Side

I used a Dremel with a tungsten bit to enlarge the snap bushing holes. I enlarged the snap bushing carefully with a step drill bit. The result is a 12' ish continuous brake line. Fitting omitted at drag brace. I will add a protective sleeve through drag brace later. Happy to not have that fitting at the brace. It did not make much sense to me or Beringer.

That's one of the benefits. I also ran one piece lines from the Parking brake valve to the wheels. Beringer also sells a fitting to connect to the Vans reservoir. Not cheap but it works.

Its finally coming together. I guess the downside is you have to replace the entire hose for a leak. I kinda doubt this happens in thst hose though!
