While replacing the entire brake system on my L-235, I've had occasion to speak with "Andy" at Matco a couple of times; He's extremely knowledgeable. Today I called him because the pads in new B5-4 brake assemblies didn't line up properly with the old disc. Andy directed me to the Technical Manual for 5 Inch Centrifugally Cast Internal Caliper Wheels which provided instructions on how to shim the axle for proper disc alignment with the pads. The manual also turned out to be a gold mine of information for all things regarding the Matco wheels and brakes. It contains instructions on how to determine when the pads need replacing (the new pads have wear indicator marks), how to set the geometry of the brake pedals vs. master cylinders, how to properly bleed the brakes, how to torque the axle nuts for proper bearing pre-load, how to mount the tire and tube, and much more. Earlier there was a discussion on how to properly torque the axle nut so, from the above manual, here is what Matco advises:

Your MATCO Mfg. wheel is equipped with Timken style tapered
roller bearings with integral grease seals on the bearing cone to
ensure the longest possible life. Torque procedures for bearings
with this type of seal are different than for bearings without them.
A common torque method for bearings without seals is to tighten
the axle nut until the wheel stops spinning freely then back off to
the nearest locking feature. THIS TECHNIQUE DOES NOT
WORK ON BEARINGS WITH AN INTEGRAL SEAL
.
The reason for using a different technique lies in the grease seal
which under normal circumstances, produces some drag and
makes the wheel feel somewhat stiff when rotated. Reducing the
axle nut torque until the wheel spins freely will allow the grease
seal and the bearing cone to rotate improperly with the wheel.
THE CONE MUST NOT ROTATE RELATIVE TO THE AXLE

1.The higher rolling drag is completely normal for this bearing and
allows for longer bearing life since the seal will keep most
contaminants out.Timken specifications state that the two 1.25 inch
tapered roller bearings used on the 5’’ wheel, produce 8-10 inch
pounds of torque (drag) when properly installed. A light coating
of grease on the seal will help reduce the drag on initial
installation. The drag will also reduce after the bearings have
been installed and the seal relaxes in the bore. It is important that
the axle nut torque be sufficient to keep the seal from rotating
with the wheel. The following technique will ensure the longest
possible bearing life.

2 Tightened the axle nut until all play is out of the assembly. Rotate
the wheel back and forth while tightening the nut to help seat the
bearings. When all play is out and the wheel rotates freely,
tighten to the next slot and insert cotter pin.

3. The rubber seal on the tapered roller bearing should remain
stationary while the wheel rotates around it. If the seal is spinning
on the axle, tighten the nut further until the seal stops spinning
with the wheel. (See Note Above).

4. When using MATCO mfg flanged axles, they can be shimmed
for toe-in / toe-out conditions or spaced out from the wheel if
necessary for the brake disc attachment screws to clear the
landing gear leg.
