Thanks Tim
How do you measure the pressure at the calipers
Thanks

Stephen,
If you have the original kit supplied break peddles you don't get enough
pressure at the calipers. The peddles need to be about 2" longer. Measure
the hydraulic pressure at the calipers with your normal foot pressure, it
will probably be 250-350 lbs. and it needs to be much higher. The low
pressure generates allot of heat and poor breaking. Call Matco, they will
tell you the pressure you need to see.

Hi Bill,
My TR-1 seems to have the same lack of breaking power! I'm wondering if I
have the original set on mine as well? I have surface groves in mine as
well. What wheels or rotor does Matco recommend?

When I first started taxi tests, I had 'severe' lack of stopping power.
Couldn't taxi and steer the airplane. We 'wore in' the pads by pulling the
plane and riding the brakes, and it became somewhat better but not good
enough.
I eventually contacted Matco, when one of my rotors developed a crack, and
they had a new owner, and had made some changes from the hardware supplied
by KIS. They changed the rotor from a cast material to a machined tool
steel. The cast iron has graphite inclusions, which don't lead to great
breaking. I think by your photo that you have the original, since the
machined rotors have some surface grooves in them. Might want to talk to
them.

Who manufactured (and model number) the main landing gear wheel assembly for
the TR4? It is for a 15X6.00-6 tire. I think it was MATCO but not sure. One
of my bearing race is turning on mine and I have some wear on the axle so I
may want to replace it.
THANKS!

Disconnect a break line at a caliper and attach a high pressure gauge to the
break line, it needs to read more than 2000 lbs. As I recall my stock
peddles produced something like 250 lb. and after the mod I think I got 1800
lbs. Check with the owner of Matco and he will give you the correct value.
He also has upgraded rotors and linings from the original ones.
