We landed at OSH around noon. We landed 27 in a strong crosswind then
taxied pretty far to the east, riding the brake as necessary. I guess my
technique needs work because I think the right one overheated. By the time
we got to HBP it was mushy, then a few seconds later it went to the floor.
I stopped on the taxiway with the other brake. EAA tied us down on the
cement at the end of P for repairs.
I pulled the wheel pant and peeked under the cowl. The only sign of any
loose fluid is out the top of the reservoir--quite a bit really. No leaks
in the cabin. And the disc looks really bad, very scored and worn. The pads
still have meat but they look sort of like the edges have chipped off.
Maybe from heat.
I replaced the right caliper a few years ago after it stranded us due to
leaking. A new oring didn't help. Same brake again.
Now I'm considering something other than Cleveland. Any suggestions?

I plan on doing the matco upgrade when the time comes.

I=99ll offer that technique is more important than which brake
company you go with. This is by no means a dig as a lot of people ride
their brakes, but I find it=99s really not necessary in the RV-10.
The F-16 was notorious for getting hot brakes if you rode them at all,
so in academics we would show a silly comparison but it worked. Two
pots of water each had a frog. On one pot the fire was extreme but
quick and the frog was left unscathed. On the other the same total
energy was applied over time through a low heat but the frog eventually
boiled. The point is, long use of the brakes, even with light pressure,
will build up much more heat than if you let the plane roll out and then
apply more pressure briefly to slow back down. Another point is landing
where you want at the speed you want (stall horn just starting to beep)
will really help the brakes. I realize that=99s obvious but
nonetheless often ignored. I=99ve also seen a lot of people jam
on the brakes to make a turn for no reason. Don=99t hose the
airplane landing behind you, but if the next turnoff isn=99t that
far and means the difference between heavy brakes and no brakes, then
another few hundred feet of taxi is worth it. FWIW I=99m on my
second set of pads at 720 hours with a long way to go before they=99
ll need replacing.
Again, this is not an attack by any means but I just wanted to throw in
my .02 to the crowd having seen a number of these related discussions.
I wish I was there at OSH, have fun!

As Coop said, it's more about technique than the brake kit, but the Matco ha
s double pads and should last longer. It most likely just boiled the fluid a
nd will harden back up when it cools down. I wouldn't do anything for right n
ow until you verify that. If it firms up and you don't get a puddle by the b
rake, then you should be good to go. When you get home you could replace pad
s and maybe caliper.
