The KRC i used on the piston engines was not really up to the task eithier. And I had a pulley on it the size of a dime.
There was a slight pullsation at idle.
The turbines will idle higher so using this same pump may surfice.
You had asked how the electric air over hydraulic work.
When 24 volt (micro switch on shifter) is applied to the coil the air from the onboard air compressor is fed to the pneumatic valve causing the cylinder to compressor. This is mechanicaly connected to
the master cylinder which is hydraulic connected to the caliper
this engages the caliper. Stopping the rotor.
Pretty neat aye?
