This is unless you are talking about the mech's breaks, as in coffee. And then, I hate to tell you, wasn't water that was being applied to your brakes, but another human generated liquid.

Whatever the water hit, it was hot because there was alot of steam. When I went back inside the break temps were in the green. Maybe they just lowered naturally and the water was just a show?

Has anyone noticed if having the parking break off cools hot breaks faster?

Nope....Generally don't need to spool them up to avoid getting the brakes hot. Certain cases apply (Hot short RWY) but it's the exception to the rule.

I was just going to ask that. Why not, if the brakes are warm, release the parking brake when the chocks are in? The big guys do it all the time. That should help cool them down.

That works well...I like to check the chocks are actually there though. A lot of times they are just thrown by the wheels and not really chocking it.

I used to do airline fueling...chocks are usually set a few inches off because the aircraft will settle while fuel is on-loaded, if the chocks are in when fueling starts, they are a pain in the @ss to remove when fueling is done.

I understand that part. I've watched rampers try to pull chocks from a fully-loaded A330 going to the UK. It was an interesting sight.

What the other poster was talking about is some of our rampers (cough-branded-cough) pretty much put the chocks "near" the wheels, as is somewhere in the shadow of the airplane. I've had more than a few eye rolls when I see it.

i used to pour water on the brakes when doing turns in an er. works great and gets them into the green very quickly and effectively (i.e. after you are done with your walk around they are green again). so BS it is not. i quit doing it though. the cracking popping sound... safe?? all the steam... what would the pax think??

if they are too hot for a TO try this: while parked with the brake set open the reversers. they blow air over the brakes and it helps cool them.

just my $0.02

I've had this happen to me twice. Once in DCA and once in DAL. Both were in the middle of the summer with short turns. One was due to the capt braking harder than I had ever braked before in my life (no joke) and it sent the temp all the way to the top. We had to wait for departure for about 20 minutes in the runup pad. He then had the never to write it up when we got back as a faulty sensor and tell MX that there was something wrong with it. I wanted to tell them all they had to do was fix the loose nut behind the yoke....

So if I'm going into a short field with a quick turn in the middle of the summer I'll spool them up about half way and do normal braking.

As far as the parking brake thing I think I read that in the QRH somewhere... Also I heard popping the TRs (if you're waiting for them to cool before departure) used to be a common procedure to cool them.

It is burning hot everytime i get close to the wheel on a walk around seems like it could sizzle abit.

I think he was talking about a mech. pouring water on the break. That's something I have never seen. It's a bad maintance practice if it's being done.
