Fred, Thanks for the reply your gallery tells a real good story on how to install them as well. I did order the  brakes last evening.

Thanks again,
Mark

This may be one of those threads that never go away entirely, and I freely admit I am committing the sin of reopening an old topic.

So Fred, how well do your brakes hold during runup?  I seem to recall that some have reported their brakes are not quite enough to keep them from rolling when at full power.

And as I recall, you use the Azusa AZ-1137 wheels, right?  What size spacer did you use on the inboard side of the axle between wheel and landing gear?

Hi Bill:
My set up, which now has a pair of Matco MC-4 master cylinders with a separate reservoir, will easily hold 2500 rpm. I’m pulling pretty hard on the levers, though.   Holding for run up is not really a concern for me.  I start the engine on the magneto, taxi out to the run up pad, turn on the secondary ignition, turn off the mag to verify that the secondary is working properly, turn the mag back on, and go flying.  The “mag check” is done at idle.  By the way, the mag drop is 100% since the tach is driven by the mag.
