rear banjo fitting
Anyone know what size the rear banjo fitting thread that is connected to the rear of the master cylinder, am going to put an inline connector after I remove the rear master cylinder but would like to know beforehand what size inline fitting will be required. I know the spanner required to undo it is a 3/4" bit unsure of the size of a inline fitting required. Hers a photo. The inline fitting will screw into the end of the hose you can see.

gibson, trying to figure out what you're trying to do, and I'm at a loss.
The brake lines, hard line and flex line are generally attached to the banjo fitting in a way that to remove them would render the line unusable.
Are you removing your rear master cylinder to work on it? rebuild it? Is the "inline" fitting you are thinking of like a quick disconnect or something?
Just trying to figure out what you're doing.

I think the two standard sizes are 10mm and 12mm ... what year bike have you got? If you have a 12 point metric socket set, it should be easy enough to figure it out by process of elimination.
Are you commencing the conversion to forward controls (with relocated master cylinder at the forward foot control) you were asking about a week or so ago?

rear banjo
Yes Priesty I am. I am keeping the rear hydraulic hose that goes from the brake housing to the master cylinder so all i need to do is put an inline connector in once I remove all the original master cylinder ect, I dont have to worry about the rear brake switch then. I have to ride 50 miles to get the new brake line made up and just would like to know what size inline connector I would need without undoing anything until Im ready to replace the line. The brake place will probably know but would like to be prepared as it is a car place.

You might try going to http://www.vtwinmfg.com/Catalog1/VTwinCatalogIndex1.htm then select "1 Big Twin 1984-'09" and look at pp. 137-141. Has about as comprehensive a listing of brake lines and fittings you'll find anywhere. Also, you might look at Russell Performance website or other brake parts mfrs websites.
I'm a little confused as to what kind of fitting your banjo bolt is going into ... ???
My understanding is you'll have a brake line going forward along your frame to the brake cylinder.
Seems like that might be a weak link, if you have a banjo fitting in the middle of your brake line ... just my $0.02 ....

brake line
Thanks for the link Preisty, I think we arnt on the same page, the connector that has the brake light switch attached is what I will screw an inline connector to, I will then screw the new brake line connector to the other side of the inline fitting (no banjo fitting) then the new line will go all the way up to the banjo on the new master cylinder on the foot pedal. Hope that explains it. Thanks again for the link.

I've drawn a crude diagram below. Both the mid-mount and the forward mounted brake master cylinder brake line use only two banjo fittings: one at the brake caliper and the other at the master cylinder itself.
With the forward mounted master cylinder I inserted a T-fitting and secured it in place where the original master cylinder mounted so I could reuse the brake light pressure switch (my motivation was I didn't want to have to screw around wiring a new one from somewhere else on the brake line).
On my bike the brake line fitting had a female threaded junction adjacent to the forward banjo fitting (by the master cylinder). I removed the pressure switch and installed it on the T-fitting. I was unable to reuse the original brake line that went to the rear caliper ....
I think that's where I misunderstood you ... I thought you were trying to reuse the original brake line that went to the brake caliper. If so, you can't remove the banjo fitting (unless I am missing something) ... that's the reason for my original cautionary advice.
Sounds like we are on the same page ... or if not, that you know what to do!
I'm sure you've got it under control ... but feel free to ask questions if you're unsure.

I haven't installed the forward controls on my Dyna yet. Is it necessary to move the rear master cylinder and rebleed the rear brakes as part of a standard HD forward control kit install?

No ... most of them just utilize a longer actuator rod. Ggibson has a set made for Softail he is using with his Dyna. There are only a handful of us crazies who screw around like this!

banjo fitting
Hey again Preisty, again I really appreciate your input. In the photo you can see the hose fitting connected to the banjo that is attached to the master cylinder. I assumed you could remove this fitting from the banjo (once the brake switch is removed), otherwise why would it have a 3/4" female nut??. Was your hose fitting the same as mine? I agree if it cannot be removed from the banjo I will need a t-piece also as in your diagram. I was going to try and turn the 3/4" fitting to see if it can be removed...not a good idea??
