MATCO Brake Assembly

I ordered and received my MATCO brake setup (WHLW50CC.75 - W50CC.75 tire and wheel assembly and the adapter MHSL-SXKIT - ADAPTER KIT, SONEX). The quality looks great and they feel like real airplane parts. As I am assembling this I am running into some issues.
- I was running the 5.00x5 Air Trac tires. They worked fine on the Azusa wheel. The MATCO wheel assembly has the valve stem hole off-center. The stem doesn’t fit properly - it protrudes way too much.
After further searching I found that MATCO offers an assembly called WHLW51CC.
It states “The WHLW51CC is machined for use with the 5.00-5 tire and tube. See the WHLW50CC for use with 11x4-5 tires and tubes or other industrial 5 inch tires.” .
Is there a difference in the valve stem location between 5.00-5 and 11x4-5? Both seem to fit the Azusa wheel just fine. On the WHLW50CC it says nothing about which wheel and tire it is machined to. What are my options? I don’t really want to run the smaller tires.
- The axle spacer doesn’t fit flush against the brake plate. The spacer rides on the washers instead of flush against the plate. Should I file down the washers to make enough room?

What mastercylinder did you end up using for these brakes?

You could try a different style valve with a new tube, I am not sure all the styles, but some research might find a more suitable angle or length.
As for the axle spacer, I would either file the washers so they sit flush or if there is room could you orientate the bolts to have the nuts and washers on the outside?
