Actually useful YouTube video about this
TL;DW; he bypasses the whole 2500 dollar software thing by using common sense that the caliper only has two wires in it so you just need to feed a positive and negative power line to it from a low voltage power source and it will extend or retract the electric caliper as needed.
While I agree with you that there’s an easy fix, it wouldn’t cost them anything to make holding the handbrake release switch enter maintenance mode.
Also, wait until they release a face lift with new some arbitrary signal to control it.
Yeah, i watched the video and the dude just yap and yap and yap non-stop, and the actual content is only at the front of it.
That trick works with all EPB, you can also take off the motor and turn the mechanism yourself, that's how all backyard mechanic does it for every car with EPB without buying the tools meant for workshop. There's nothing special to it. Dude could've save a lot by send it to dealership instead.
Edit: also all car with EPB works that way, this is not uniquely hyundai, you need a scan tool to retract that piston, or you do it the way backyard mechanic do. There's like so much unnecessary drama here.
I'm a mechanic and no, you cannot do that
What's the odd, i'm a mechanic too, and yes you can, you just don't know about it.
I dunno what that link is but no, you can't. There's no way to turn them.
partial bullshit… it's definitely a trend but 2 years ago I did the breaks on my buddy's Ford Explorer 2021 (not 100% on the year). It had EPB but also a dash sequence to enable maintenance mode
Hyundai is not the only brand for sure but the paywall is just unnecessary bullshit
Well maybe not all, but how many out of that 1 model have that maintenance mode? I work on many, none of them have it. Honda, toyota, subaru, vw, even chinese brand like geely, all required a scan tool. The good news? A generic scan tool is enough to set it, doesn't have to be an expensive proprietary tool made just for that specific model that come with those bs. The bad news? Car maker only release it to aftermarket scanner after a few years or so, like the hyundai ionic 5 here.
And even then, like i said, you can just unbolt the motor and turn the piston. 20 years in this industry, this is the first time there's this much drama on basic shit like this.
agreed 100%
ps: I re-read my original post and realized I came across as if I was fighting you… I just really wanted to point out this issue is a matter of greed and not a consequence of EPS tech
The drama is that this is an entirely unnecessary step that adds extra work for the technician/owner that wants to change rear brake pads/rotors, which are a wear item.
I’ve been doing brakes on mine and my family’s cars for over a decade. It’s dramatically cheaper to buy pads and rotors and swap them myself, and if I do it myself I know that it was done right and there’s antiseize everywhere it should be. So now in addition to all the work of jacking the car up, removing tires, removing the calipers, depressing the caliper, cleaning the hub, coating the hub with antiseize, cleaning the guide pins, reinstalling and torquing everything to spec, I now have to get a battery/transformer/charger and wire into a sensor to tell the stupid fucking computer that the pads and rotors are new. Why can’t the computer use a position sensor to just detect that there’s now thicker material there? Why isn’t there just an option in the maintenance settings that you can press to say that you’ve done the work and to reset the maintenance interval? Fuck this shit, doing brakes is already a time sink if you live in the rust belt, and this system adds nothing but an extra cost or extra work to the person performing the work. There’s no safety gain from it existing, it’s fucking stupid.
For us technician? It's a very quick work. For you guys? It's an additional 30min per side, give or take, and for a job that you'll be only doing once per few years if you don't drift. Rear brake wear significantly slower than the front, and this is a rear brake issue. That's the drama. You guys are crying about additional work for something that you do once a few years.
How’s that boot taste?
Tastes like heaven for this jack off. 🙄
You sound pretty stupid. Even if you were right, this is wildly unnecessary to go through to change brakes. I’ve been changing my own brakes since I learned to drive and have never had to touch anything other than the wheels and brake pedals. Your take is wild.
