Motor Break fail? 2016 RXV

[trevorg7]

Need some advise team, I had Bob Boyce come out and program my cart this week in TX and the first time driving it post upgrade I believe the motor break failed. Cart stopped in this tracks on then road and wouldn't move.

I talked to Bob, he advised it was the motor break and I removed it and pushed the cart home. The motor break smells burnt, event a day later.

I removed a Matrix #617766 motor break; pic attached. In my haste last night I ordered this from Amazon https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 but now realized it doesn't have a wire harness. Can I open it and wire in the old one?

Any advise would be appreciated.
