Dave,
Actually my brakes work reasonably well. They will hold fine for the
runup.My problems occur when I make a turn. The Maule tailwheel unlocks too
easily and full braking is not enough on one wheel to counteract the turn. I end
up stuck with the tailwheel 90 degrees to the direction I want to go. More
engine power only ends up pushing me the wrong way. Sometimes I have to get
out of the airplane and straighten the tailwheel. I can mash the brake to the
floor and this still does not help.Manytimes I just do a circle in the
wrong direction in order to end up headed the way I want to go (if this makes
any sense)
I think the problem is a combination of, weak brakes, too easily
unlockable tailwheel,fat tires (although the beer is GREAT !) and grass. I don't
have
too much of a problem on pavement.

Dick, I don't what to tell you about the Matcos other than possibly
install new pads. Often, if the pads don't get broken in properly they
will glaze over and not have full braking potential.
As for the tailwheel unlocking too easily, all you need to do is loosen
the springs a little bit. I don't mean give them a bunch of slack, just
not so tight. The tighter they are the quicker it will unlock. It's
all in the geometry of the cam. Experiment a bit and you'll see what I
mean.

Hi Dick,
If they worked well before this issue then you should be able to save them if it
is only a glazing issue.
You are right to want the brake to be able to lock down when you need it. Take
the Matco disc off and de-glaze it with some 360 sandpaper. Don't be afraid to
do a good sanding job. If the pads are worn down quite a bit then get new ones.
If they aren't and they are just glazed over then you can try to ruff them
back up a little and break them back in. Use some 220 sandpaper on them. If this
doesn't work then it look like new pads are in your future. I have Matco's
on my plane and can lock them down with the parking brake and run my engine at
full rpm and they will hold without any creeping. I have installed 30 odd some
sets of Matco brakes on CT's alone and I'm an OEM dealer for Matco. If you need
a set or parts let me know I can get you a better price. They will work if
broken in correctly at the start of their life, but like any brake they can get
over heated and glazed, but this can be fixed.
The other thing that effects brake pressure is the angle and setup of the master
cylinder. Smaller brake line ID is better than larger. 1/8 ID is better than
1/4 ID. It takes less fluid volume and master cylinder travel to give higher
pressures with smaller line than larger ID brake line.

I don't think even good brakes (which I have) are useful to overcome
an inconvenient tailwheel. There's just too much leverage
differential. If I find the tailwheel inconveniently oriented I
generally correct with lots of power, even full power. The IV's
rudder and elevator are large enough that a big blast of power with
the stick forward and full rudder generally corrects any tailwheel
orientation without much forward travel. Of course you must be aware
of what's behind you, and if power would be inconsiderate the only
thing you can do is get out and muscle it around.

I do that too; sometimes even on the runway. :-D

About the Maul tailwheel. You have to adjust it... The tail wheel should
not unlock when the rudder hits the stops=2C grind whatever on the assembly
to make that happen. Then=2C when the tailwheel hits the stops=2C it ha
s to compress the spring to release. Do this and you will have no problem.

Lots of guys up here don't run any springs on the tail wheel of cubs. All turning
is done with braking and power. I tend to use my brakes a bit more than rudder
on the ground work too.
