The quick answer is yes but the question implies that your understanding of PPC operations is not adequate for the design of a successful unit.

First, will you be on concrete or grass? I am not convinced you will need any wheel brakes. A steerable wheel would be much more useful and that may not be required.

Landings and aborted takeoffs are made by killing the engine so the lines do not contact the spinning prop and the wing provides more than enough stopping power. I have difficulty envisioning a field with enough slope to require brakes.

I can see you may want the brakes in a big heavy high power (rotax 912) two seater but I was under the impression your plans were for more of a powered paraglider.
