What size and thread are big red caliper hard lines?

I am installing big reds (993TT fronts 964Turbo rears) on my SC that had front A and rear M calipers. I notice the hard line fittings do not fit the new calipers. The threads are the same but the screw bottoms out before the line seats in the caliper.

The new calipers are in a different position to the originals, so I suspected I might have to replace the hard lines anyway.

I was thinking about using one of the longacre kits to redo the system as everything other than the master is still original to the 83 car. I was considering this one:

Longacre Racing - Online Catalog: Electronic Wheel Scales, Gauges, Pyrometers, Chassis Setup and More!

The kit states it does not come with the caliper fitting.

Whats the proper fitting for the caliper? And do I want AN3 or AN4.

I guess for that matter, what is the size of the master fitting also since I'll need to connect that to the longacre kit.

Thanks!

Not sure if they are the same as my 996TT calipers but i had to fabricate new hard lines anyways because the original 911 ones were too short,but i used the same fittings on my 996TT calipers.
I can't see why the fittings would be different ...

Cheers!

the fittings are the same. metric bubble flares on the lines with m10x1 threads on the fitting.

I promise you the nut on the flared fitting bottoms out in the caliper before the line pinches. It looks to me like a banjo fitting is called for.

I bought the kit from VCI but I did not receive any hard or soft lines. I've let them know the parts are missing and am awaiting a response.

I think you may need to adress Bill Verburg on this one,he is the resident brake GURU on this forum ...
If anyone can answer you,he's the one !

Cheers!
Phil

but anyway the fittings are 10x1.0 and the line for a 911 is 3/16"(4.75mm)

there are 2 ways to do it
1) with a hard line from the caliper to the strut boss, then a flex line to the body lines
2) 1 longer flex line from the caliper to the body lines but held at the strut boss to prevent whip.

Thanks Bill.

VCI has lines on the way.
