Hi all, could someone tell me the size of the flex line that runs from the tab on the shock
tower to the caliper? Either in 'dash'(AN) size or fraction. For a side entry caliper.

Dan, I have a -3 line for another application and it's banjo is too small for the banjo bolt in
the caliper. Do I simply get a smaller bolt, same thread size?

Hey Greg,

I think both 3/8 threaded fittings and Metric fittings can be made on -3 hose. Do you have machine made hoses or re moveable fittings? S3 brakes should use 3/8 fine threads.

Roger, I don't have hoses yet but I found a smaller banjo bolt in my stash, 3/8 x24, and it fits
the -3 banjo line I have perfectly. As you can see in the pictures, the banjo bolt that came out
of the caliper is too large for the -3 banjo but the smaller bolt (screwed in the caliper in the pic)
is perfect.

Thanks

maybe oil pressure line. Sorry but all my [*]banjo stuff is 900 miles away. I can look in another month and a half.

No problem Dan, thanks! I have a couple of friends there now.
