Replacing the front brake lines on my M800, and apparently there are two choices for banjo bolt size: M10x1 or M10x1.25 (I'm replacing one of the caliper banjo bolts with a double.) Can someone confirm which is the right size?
All the ones I've seen on Ducs are 10x1.0

Anything newer than the early '90s are all M10x1.0 thread-pitch for all brakes and the clutch as well.

the bolts on my '83 Pantah and my '86 Alazzurra are 10x1 too.
don't know about the Darmah and the GTL. For all I know they are in Arshins.
AFAIK it's brembo that sets the spec -- all the Italian bikes I know off that use Brembo have 10x1 banjo bolts.
Thanks - will order the 10x1 double.
On a related topic: How do I specify to Spiegler the relative orientation of the 2 banjo fittings on either end of a brake line? Both ends of the line need a bent banjo fitting, so how do I tell them the orientation?
There are two numbers. Angle of the banjo and axis turn
Make the master zero deg on the axis of the hose facing the master. That means the part closest to the master. What angle is it? Write it down.
Now lay the hose flat with that part down. How does the slave end look in comparison? If it is not at the same zero how much turn is it? What angle is the banjo relative to turn?
Try it with an old hose it makes more sense visually.
When I have hoses made I fax them a diagram to be sure.
Thanks, Ducatiz. Faxing a diagram is a good idea. Too bad my 3-D sketching abilities suck...
Just FYI on this: Spiegler emailed me and apparently the end fittings are "clockable" by the customer, using a tool that they supply with each order. So only the banjo angle needs to be specified.
That's handy!!
The Spiegler usa website has diagrams for all different configurations of fittings.
When I ordered mine from them, I sent a pic taken with dig camera and they were able to ascertain from that. all three line came back perfect. Used string to figure the length, since they didn't info on '00 M750 dark.
I'm thinking of a different routing than stock, because the clip-ons have changed the arrangement of things. Maybe a digicam shot with some editing, thanks for the idea.
My biggest worry was the "clock" orientation, which, even if slightly off, would twist the lines. These clockable fittings that Spiegler has solve that nicely. As long as the fittings seal right...
Hydraulic swivel fittings have been working right for years.
It sounds like the Spiegler fittings are just a version of them.
Goodridge also has them. They make the joint bulkier but not by too much. Some ppl don't like the look. It would be better to have a swedged banjo on the master end and a swivel on the slave side where you have more visual room

I agree. I asked Spiegler about that configuration, and they replied that all their fittings are "clockable." So there you have it.
There will be no FHE for me on this - just rerouted the front brake line to go under the gauges and it worked fine, so no need for custom lines! [beer] Will be spending the money on respringing the rear shock [thumbsup]
Slightly off topic - I have a friend that wants to swap the banjo bolt and bleeder bolt on his gold line caliper - he says it clears out better that way. Anyone know any reason why that would be a bad idea?

How about it won't work?
The banjo bolt is an open hole into the fluid chamber.
The bleeder has a machined seat to seal.

Are you saying the bleeder won't seal when threaded into the other hole? From his question, it sounded as thought he had swapped them already and was worried about safety, though it's hard to say for sure.
Both holes are machined for a bleeder on mine.
Banjo bolt doesn't bottom and seals with the washer

Sounds good - I'll pass it on.
I got used to it after a while - I'm sure you will too ;D

I've been wrong probably longer than you've been alive. ;)
