quick disconnect brake lines
Ive always wondered about them and swapping out entire brake assemblies instead of taking the time to swap pads. Then I finally saw being used at the rolex 24.
does anyone have experience with them?
The ones ive found are supposed to seal when disconnected - Are they set up with fluid somehow or are they (caliper/ line assembly) installed initially into the car to get fluid in them, uninstalled and then put back on when necessary?
do they ever have issues of leaking or weeping?
do they ever spontaneously detach?
I have no current use for them, but Im just interested in learning more about them and if any corvette people have used them

At $2,000 per wheel, I don't think there will be many forum members experiencing them. The announcer said that they come full of fluid and just attach with 2 bolts that are already secured in the caliper. I just saw them change the fronts only, don't know if any rears were changed. I would think so

I asked that in the other thread. Apparently the sub-assemblies are put on the car and bled, then removed and kept ready to go. The fitting is designed such that an air bubble doesn't get created during install.

I don't know where he got the $2000 for that either.
When they go and do this, they fully assemble the corner and bleed the brakes. Once it is done, you pull the corner off just like it is and put it away for when you want to do the change at the track.
But there is more than $2000 in THAT corner.
Depending on the car, and size some of those DP cars can have more than that wrapped up in a rotor and hat. Add in the caliper, lines, fittings, and pads...you can easily be over $5500/ea assembly.

thanks for the replies!
considering 2k per corner less than what an expensive street setup runs. Im wondering if they got most of the parts for free... or forgot a zero

Keep in mind you have to have at least 3 sets per corner. 1 on the car, 1 for scheduled change, 1 for the inevitable Murphy moment, and the good teams probably have 1 or 2 more because there's a lot of Murphy in 24 hours.

Going off the GT2 car, which Riley built for us I would figure
$1800 hat/rotor combo
$4105 caliper
$450 pads
$29 caliper fitting
$100 line
$150 QD (I think)
$32.10 bolt, ea
Rough cost per corner for the fronts would be
That would be per corner....$6698 roughly, I don't know if GA has a limited cost on the calipers for that class or not.

$117 for the male side
$130 for the female
Only $247 per joint.
That's why some teams still do it the old fashioned way.

Yeah we ran the staubli QDs and they are real nice and $$$$$. Like Anthony said, $2k is low if the mean the whole brake setup per corner.
There are cheaper QDs but the cheaper they are the heavier, bulkier and leakier they are.

Oh, and announcers are shooting from the hip when talking. There is room for an error or two.
I looked at quick disconects from XRP while at the PRI Show but didn't get the price on them. We had quick disconnects in -2 size on the IR seeking head on the F-106 for the cooling way back in the 60's. I brought a couple home after we did a modification but have not found anything to use -2 size for.
