Moviemaker, No. Usually you have to apply 24vdc to those 2 wires to release the brake. If you can post a picture of your set of motors I would be glad to help you through the removal of the brakes. There are several different models and a pic would be helpful. I have 2 different sets of these motors, one set for shoulders, and one set for motion.

ok, thanks kamaroman. It will take me a while before I can build up enough energy to turn that sucker over again. I have a bad heart. It may be a few days. I have already cut the wires going inside of the brake. I sort of understand that the brake works when the power is removed so if you fall off of the chair the brakes go on so it doesn't run over you.

I may have clipped too soon.

Thank you so much!

Let me know if you need any help with it, its actually not to bad a job to do besides turning the chair over.

Thank Both of you so much

It is super easy. I used the same video on my 600xl's. All you need are some Allen wrenches and a Philips.

This web forum thread has some excellent photos:

Brake removal

Keep your brakes for later, I installed two encoders (which are possibly too small) under the cap where the brake used to be.

I can post photos later if you like.

@All I didn't remove mine. I wired them up so I got this big red switch in the back of doom as an emergency kill switch. Is there a benefit in removing them, besides the extra unnecessary work, that I'm missing? Some enlightenment here?

@mdeming1 What are the encoders for ? Isn't PWM enough if it's for speed purposes?

The encoders are for feedback from the motors to the mpu so it can make up for skew and other stuff that is not right on target.

The only problem leaving the brakes on is that they do use power (how much, I don't know) in order to keep the brake off...
