Both systems however rely on the power of your master cylinder.
The Ercoupe master cylinder (Scott) was speced for the original
Goodrich expander tube brakes. The requirement was high volume, low
pressure. The original cylinder still works satisfactorily with the
Goodyear brakes, but when matched with the Clevelands, cannot muster
enough pressure to do the job.
Skyport has an STC to install a custom manufactured Matco master
cylinder, which works with the Goodyears and Clevelands but cannot
move the volume required by the Goodrich brakes. An off-the-shelf
Matco from Aircraft Spruce will not fit the application as it is too
long overall, nor would it be legal without a field approval..
