Today I temporarily mounted my shiny new Matco B5-4 brake assembly on the left wheel, and hooked up my shiny new Russell 18" motorcycle brake hose and tied it in with my shiny new heavy-wall Nylaflow tubing. When going from the original Rosenhan brakes to the new Matcos, some shimming is required between the brake mounting plate and the axle. The old Rosenhan die-cast mounting plate was .210 thick, and the new steel Matco plate is .125 thick. I'm still working with Matco on the proper dimensions...The length of the axle mounting bolts have to be adjusted accordingly.



Although I still need to shim things up for proper brake pad centering, it looks like the new model should work. I had to saw off  1/4" of the mounting bolt and use a reduced-dimension metal locknut where it interfered with the middle gear door bracket. S.O.P:



I plan to wrap the bottom 5" of the teflon/ss/vinyl brake hose with Thermoflex for added protection.
