2017 MX - Integrated Parking Brake stuck - can i remove actuator?

[tommytuna]

HI Folks - i have the integrated parking brake / single caliper setup on my 2017 MX. I have the dreaded parking brake fault and can't get Telsa out of garage and a tow would be super expensive.
I've seen multiple videos / tutorials on how to remove the actuator from older X/S models where the parking brake was a dedicated caliper/actuator. In mine it is all integrated with the main brakes. I can definitely see an actuator bolted onto the back of the calipers and a wire harness. I got the part numbers and retrieved below.

Questions: can i simply un bolt that actuator and remove it like in the previous generation of parking brake? and simply manually back out the actuator rod?
Anyone have a tutorial/advice how to remove this ?

Below are pictures of the parts including a breakdown. Doesn't look like you can pull apart the actuator and grease it like with the old ones?

I don't have any answers but just watching the thread as I have a 2017 as well in Chicagoland (snow/etc).

Aha, u have Mando brakes... i'm not sure when they started putting these but see some parts around..
Looks similar to VW, check this video

Same principal, just harder to get at that shaft

Well i got myself into bit of hot water. I got the actuator off but the screw head broke off. It has a weird gear pinion that goes into the brake assembly and i had no way to manually turn that. I tried all sorts of bit shapes and nothing was snug. I guess it is tow time + expensive replacement of the rear brake assembly. Grrr.
Note if you unplug the actuator, the car remains in a fault mode and won't turn off. I had unplugged and came back hour later and car wouldn't shut down or do anything. Had to jack it back up and plug in the faulty actuator. POS

Wow. Very sorry for all trouble and you put in quite the effort on this. Hope it doesn't cost you too awful much.
Makes me want to schedule a clean and lube of my brake system in the future. I did have to replace my front rotors in Sept '21 because I let it go on too long before a clean and lube.

Well it was worth a shot to see if I could drive it to dealer and save $200 on the tow. I believe that entire brake assembly will be replaced by Tesla and probably overdue at 140k kms. Only saving grace is failure happened in garage vs on road trip. We will need to get the car out on skates and a flat bed. Good times

Anybody have any estimate on what it costs to replace the two rear Mando brake assemblies? i believe they come with the parking brake actuator pre-installed as one unit.

Pretty sure labor should be small, caliper replacements are pretty easy and quick.
Not sure about new parts but used ones range from $150-450...
