I have the The Art of Wheel Building book and I am trying to get my head around the lacing pattern for disc wheels. Am I correct in thinking that for the front wheel you will use a symmetrical pattern for the braking spokes with the braking spoke having the spoke head on the inside of the flange and the rear will have to use an asymmetrical pattern as a result of the the pulling spoke on the drive side running against that of the braking spoke on the non drive side?
Makes no difference.
Accepted wisdom is as you say but in the real world nickjb is right. I lace my wheels symmetrical as I like symmetry and I like that traditional types don’t like it 😀

I LOL at how crap like this gets trotted out by "experts" who've sold books off of it, it's nonsense.
Outside in from both sides, rotate the hub counter clockwise, inside out for both sides and cross as required. Evenly take up the slack, true and finally tension. It's not hard, it's not complicated.
Consensus has it that it's complete tosh. Thanks all!
And there was me thinking this was going to be about snowflake lacing.

As mentioned above.
It’s pish.
My 120kgs, racing downhill, jumping, smashing down Alps....
Only ever built wheels the regular way. In fact, I’ve never even considered which ‘direction’ the spokes go for inner, or outer threading. Just laced ‘em up and bashed them around a trail.
Since I’ve started building my own wheels, which is about 20 years, I’ve yet to bend one.
Pish or maybe laziness by some wheel builders - as the link above indicates it's not just a Shimano recommendation or something dreamt up by book writers. And further searches show DT representatives recommending the same.
However real world use for most, myself included, shows no discernible difference, I just like to build them that way.
But don't get me started on lining the valve hole up with the logo 😉

Did that. Then considered how they applied to my use and disregarded them as not applicable.
Despite the link, diagram and ALLCAPS jest above, last time we discussed this I also found some well reasoned explanations of the other position i.e. that it doesn't matter very much (better explained than 'it's pish'/'not applicable'/'i've always done it this way/etc).
The reasoning was that the maximum torque during braking is still relatively small compared to the other forces the wheel sees in use making adjusting the lacing pattern not very relevant for disc braking vs rim brakes, so long as it is tangential and not radial https://www.wheelfanatyk.com/blog/issues-disk-brake-wheels/ and Jobst Brandt said the same.
Personally, I still felt it was sensible to continue following the majority of recommendations and lace as per the shimano/mavic/dt swiss/magura/sapim pattern and instructions. Since I'd never laced a wheel the other way it didn't make any difference to me. You buys your spokes and you make your own choice.
The valve hole thing gets easier too. In a 3x wheel you'll be putting the first spoke (leading to the hole bedside the valve) in the 4th hole away from the logo, 3rd for 2x, 2nd for 1x and of course 1st for radial.

Unless I'm misinterpreting that I actually do the exact opposite?
Front disk side the braking spokes pull the spokes in at the final cross, i.e. they exit on the inside of the hub flange. that way under braking the spokes don't bow out and brush the caliper (seems to be less of an issue than it did 20 years ago).
Front non disk side, make it symetrical.
Rear drive side, definitely the opposite, if you have the chain come off you want the braking spokes on the outside so that the chain doesn't slide down them and jam against the cassette. Yea yea yea...... set your limit screws correctly.......... ****ting a rock with the dereilieur and all that goes to piss anyway so why not be safe?
Rear disk side - same as the front.
That's exactly how the Art of Wheel Building shows it as well.
