Re: Brakes won’t “set”
The only time I've seen a delay in applying the parking brake upon stopping is if oversized tires or speed gears have caused the controller to go out of calibration with the final effective gear ratio. The factory default motor maps support tires up to 20.5" in height, and I never edit those maps unless I am forced to due to that reason when tweaking an RXV in person. The only time I've usually seen this happen is when tires of 22" or larger are installed, or speed gears have been installed in the rear end. That would cause exactly the issue that you are describing. Poor regen/pedal braking and a delay in applying the parking brake.

The delay in parking brake applies even on flat ground, not just when there is increased effort to slow or stop the cart. After this happened we had issues getting the cart moving again. It’s like the cart had no power. I cycled it on and off and eventually moved fine. It’s very bizarre... my wife was cruising around the complex with the wife, she stopped talk to me and the cart stopped fine. She then gently pressed accelerator to go but After a short distance pressed the brake to stop again, the cart did not stop. This is when she pressed the brake all the way to the floor and the cart eventually stopped. So stopped fine once and then 10 seconds later did not stop appropriately. I took it for a drive afterwards and this is when I noticed that parking break does not set when you stop it. It doesn’t “click” like my other cart does. So you think this is something in the controller that is off? |

Re: Brakes won’t “set”
Correct, it is the original controller. You programmed it for me right after you got back from Florida.

Re: Brakes won’t “set”
Yes, I remember that. I was beat from the trip and I was getting used to using my new Linux OS laptops. I'll have to look at the file I saved of your controller prior to reprogramming it to see if there was anything there that might hint of an issue like this.

Re: Brakes won’t “set”
Are you letting the go pedal come all the way back up? It might think that you are still trying to go.

I was wondering if there is a bad accelerator position switch that might be an issue as well. The cart certainly does take a while to “lock” after it stops. I have noticed even on very small grades that I will get off and it will move a little before it stops. Maybe 5 seconds or so. I am not sure if it’s appropriate function or not but in my other RXV (danaher), once the cart is stopped and before I get out I press the brake probably 50%-70% and I hear the brake click and the cart is secure. Obviously if I turn the key off, I get the same click, but I don’t always turn the key off if I am just jumping off the cart for a couple of min. |

Thank for looking into this for me. I am happy to send the controller back to you if you find something that needs to be fixed. It is something a shop can fix, I can do that as well. I actually have an extra brake from my other cart. I changed it just a precaution when I got my other cart. I don’t think there is anything wrong with it. It’s off of a 2011 RXV. Steve |

Just following up to see if you had a chance to check your files for my controller. Thanks, Steve |

Re: Brakes won’t “set”
Not yet. That laptop is out in the trunk of the car and the weather here has been very unpleasant over the past few days. I do not like carrying it in or out in the rain.
