It is standard to have the longer stroke when one has the 6 disc system.
Shops that have experience installing them will tell you that it works
better after you run it in.
We know lot about that system as we sell all type of system and personally
use them on my coach.

You should try using one of the small conical copper washers that go between the casting seat and the bleeder screw. It will deform to take up the imperfections in the casting to allow sealing.

Emery, I bet I’ve spent two hours trying to find those—in stores, online,
anywhere. Searching finds copper washers for flat bolt heads and banjo
bolts. I see flare gaskets, but those are sized for tubing flares and I’m
not sure they’ll fit.
If you know of something sized for M10x1.5 bleeder screws, I’m all ears.

They are commonly used in the refrigeration and air conditioning trades.
You might try there.

Hi Rick, refrigeration supply houses, AC parts stores, or roll your own. Flare a 3/8 or 1/4" tube and cut off with a dermal. One should last thru many bleeding. Copper will swell and soften if heated. Push come to shove put a bleeder upside down in a vise and find a short piece of copper the size of the fluid hole and heat one end with propane torch and drive it down on bleeder to flare. Let it cool and cut flare off.

Emery, I have the McMaster app on my iPhone, I use so often. :)
But they didn’t have comical sealing washers. They DID have flat ones that
I think are the right size, and I bought a box. A bleeder screw will make
it conical, even if I have to use it as a die with a hammer behind it.

pretty easily” Denney

I bought mine off the local Grainger store. They had to have them sent from the warehouse, none in stock at the time. I got the first five sizes because I didn't know what size would fit my oozing oil cooler lines. They were cheaper'n vomit. Also, the Oil Cooler Line Guru, J.R. Slaten had a complete kit of them in a plastic container. Might "'ast 'im" where he got it.

I have to use them on my steering box because I cannot stop the drip from a line no matter how tight I make it. I even had a new line made (cost $65) and that didn’t help.

Lanier Hydraulics made me a line that doesn't leak. $25 I believe, using my existing connectors - the ooze was on the line side of the connector.

I ended up buying Parker 2GF-3 copper flare washers on eBay, and they were
the perfect size for brake bleeder seats.
I was also installing Performance Friction pads on the rear rear wheels.
Both bleeders on those calipers were seeping, so I put washers in both of
them. I think that addressed that.
But I was unable to fit the caliper with the PF pads over the rotor on the
starboard side, and the piston could not be retracted further by screwing
it in. I had to put the other pads back on. I truly hate parking-brake
calipers, but these are worse than most.
And my parking-brake cable is binding and won’t release fully. If I want
the mechanical parking brake to work, I’ll have to order new ones. Maybe
I’ll get around to that.
And my port-side leveling valve (the one I DIDN’T replace two years ago) is
leaking. Got a new one of those on order from JimK.
And my supplemental vacuum pump isn’t pulling much vacuum. Got a new one of
those on order, too. Expensive buggers, but this one claims to maintain
18”Hg at a minimum. The one I’m replacing only pulled 15” even when it was
working properly.
Anyway, I’ve posted an album about this year’s rear-disk-reaction-rod
project, which covers the many unexpected issues I had. I hope nobody looks
at my workarounds and tells me I’m doomed.
http://www.gmcmhphotos.com/photos/g7241-manny-brakes-installation.html
(Jim Hupy, I measured the runout of the rear rear rotors—.006 on one side,
more like .020 on the other. I’m not happy about it, but I don’t really
know what to do about it, either. About .005 bearing play on both side,
measured at the rim of the rotor. I should have gone with my first instinct
and not measured it.)

Jeeez, Rick! What a lot of trouble you had. I thought my 1st production
run problems were a hassle, but they were very trivial compared to yours --
I hope. I HOPE, 'cause now I wonder whether I checked everything closely
enough. And after probably 50,000 miles, I'm afraid to go back and check!
:-)
By the way, looking at your combination valve mod, I'm hoping your next
project is new brake lines! :-(
Oh yeah, in the first photo, what's that sleek sorta boat-prow looking
thing on the right side?
