Cessna 208 brakes are ineffective

As of SU5, the Cessna 208 brakes are really ineffective during taxi especially with the higher thrust at idle than I would expect.

Taxi in beta range.

Thanks for the heads up - how do I select “beta range”?

Pull throttle right back to basically reverse the thrust. Don’t stay in beta for too long, go in and out of it. Condition lever to low idle, ie halfway, open inertial separator.
Don’t forget to close inertial sep once you’re up in the air and condition lever to full for take off.
