if you have no brakes at all, that cyclone is on it's way out....i've had 2 do the exact same thing. i dont want to alamr you but that was my experience in the last 4 months.....are you running mod?

I m running stock for the time being, it seems to be intermittent sometimes i have brakes sometimes I havent.

Is i the FETs on the way out?

Put your EPA back to 100, reset your ESC. If that doesn't work....Well, as Mr. Santinuchi said, she's done son. I had the same experience with my Cyclone.

Like everyone else has mentioned try reprogramming your ESC and giving it another shot.

If it still doesn't work it means that the brake fets are probably shot.

99% of the time when I see this sort of thing it is the result of not running a schottky diode on the motor.

A schottky diode acts sort of like a one way valve protecting the ESC (the brake fets are first in line on the way back) from back voltage/current that is caused from braking and from coasting.

Unfortunately, adding a schottky diode now will not give your ESC its brakes back.
