Left Brake fault
hi, Please check the lead and the fitting to the controller, it 's rare for the controller to have this problem, I have repaired that very fault recently and it was a high resistance cable fault , now measure the brake cable from the controller , disconnect cable and put the electrical meter on the lowest ohms reading, now it should read from 0.4 to 1.0 ohms any more and that's what causing the problem.
Regards

My pronto m51 sure step service light is flashing
sarah check the joystick cable try unplugging it from the rear of the joystick and plugging it back in then unplug it at the back of the chair and plug it back then turn the chair on to see if you are still getting 7 flashes. If you are then you have one of 2 problems the joystick cable somehow is bad or the joystick itself has got a problem try the cables first to see if it fixes the problem If Medicare paid for the chair then they will pay for most of the repair Contact Roadrunner Mobility @ 1-800-467-2668 Hope this helps you

When I drive forward and move the joystick to center the chair is still moving for the few fit before stops.
If the brake is applied by electromagnetism, power must be supplied to the coils by either manual or electronic switching.
I suggest you investigate the circuit to discover how the power should be supplied to the brake coils and then it will be easier to trace the fault.
As a matter of not unrelated interest, it is fairly usual to arrange the wiring/switching so when power isn't being supplied to a low voltage DC motor the motor terminals are shorted. When being pushed the motor becomes a generator and the input becomes and output and so shorting that output makes the motor self-braking to some extent - this is why car windscreen wipers are able to stop almost instantly...
