Changing rear brake pads, ZS EV, does anyone know if its safe to do it yourself.

Does anyone know if its safe to change rear break pads yourself on a, 2020 ZS EV, Hi, I have quite a bit of car DIY experience and i normally change my own break pads when needed, previously on Peugeot and Renault cars but i was wondering if anyone has tackled this on a ZS EV, I would assume you would have to leave the car switched on so that the breaks stay off, but i read somewhere that if no pressure is detected between the pad and the disc the piston will come all the way out and that will be a major problem.

You will need this to free off the brakes.

Different vehicle, same principal.

Maybe check out this thread.

Park brake motors burned out (service mode)

Late 2020 MG ZS EV, approx 60k miles. Hi, I recently had my rear brake pads replaced at my local garage. They advised me that there was now a warning light on the dash (autohold fault). Not only that, but the parking brake also doesn't work, meaning I had to put logs behind the wheels to stop...

If you want to do DIY stuff, I would recommend downloading service manual - should be worth every penny. Search the threads, I posted some links previously.

One thing to remember - if you still have a valid warranty, whatever you do on the car yourself could invalidate it.

I seem to remember reading in a thread, that even a few MG dealers themselves, had found a problem when selecting the handbrake service feature mode on their diag computer ?.
Regarding the warranty, if the work is carried out correctly using genuine MG parts, the warranty should not be compromised.

The only tricky bit will be putting the EPB into service mode. The dealer can do this easily using their computer but it's not so simple for the home maintainer. I was recently looking at some OBD2 handsets that claimed to be able to do this for certain MG cars but I haven't seen anyone actually try it.

Piece of cake with a 2ft broom stick.

I couldn’t find any info on how to change rear pads so decided to have a go. Looks more daunting than it is.

With ignition off, popped electrical connection of the rear brake calliper, connect two wires using insulated spade connectors to the pins on calliper and connect to a 12v battery. Depending on which way round you connect it to battery the piston will either wind in or apply more pressure to disk. Don’t over rewind.

Remove calliper, change pads, change disks.

When you’ve changed pads and or disk reattached everything. Lock car and it will automatically apply the brake.

No warning lights, all works. Almost out of warranty anyway and cheaper than the £400+ they wanted whilst servicing to do job.

In my experience the MG warranty/ stealer has been useless so far anyway so am happy to do my own repairs.

Did you need to have the handbrakes released or does this method release it?
