Question.. cant get my head around it.

There are two ways to use the Mechanical brake. If you have a 3 channel radio, run the brake on channel 3 and use servo mixing with the throttle channel. If that is not an option, use a y-cable on the esc. You will need to disable esc brakes on these as well. Many use motor brakes in heavy trucks without a problem. I use motor brakes in a 5.5kg truck and have no problem. I would make sure you are not at the voltage/current limit of your esc if doing this, leave a little headroom. I am using 6s on a 8s controller to give a little headroom.
