Nissan Ariya Rear Pads

[mitch05]

Hi all.
2022 Ariya evolve 87kw
Needs rear pads and garages either can't get them or can't book it in for over 1 week.

I've changed pads on ICE cars before but I'm wondering if it's the same on an EV?
Just thinking I could get the pads and fit myself?

Electronic handbrakes usually need a scan tool when you replace the brake pads.

What’s different on the Ariya (important bits)

1. Electronic Parking Brake (EPB)

The rear calipers have electric motors instead of manual handbrake cables.

You MUST put the EPB into service/maintenance mode before pushing the pistons back.

If you don’t:
• You can damage the EPB motor
• You can trigger fault codes
• You may lock the brakes on

How to do this:
• Best method: OBD scanner/app that supports Nissan EPB service mode
• Many decent aftermarket scanners can do this
• Dealer CONSULT is the official tool, but not required if you have a capable scanner

Because the question was asked, and this directly answers it.

Yeah electric handbrakes are nothing new. The DIY approach is use a wind back tool rather than the plugin service tool. Can be had for less than a £10.

I was quoted £180 by Halfords for a job that cost £30 and half a day, I used an oem quality pads too. The bit I don’t know is around the regen stuff. Not sure if it would need resetting or not.

The problem is, AI is very often wrong, but written in a confident manner as if it was created by someone with solid experience of the task at hand. But, if you just copy and paste something from AI, you have no idea at all if this is actually correct, or whether there is anything a bit weird about the Nissan which could lead to someone making a dangerous or expensive mistake.

In other words, if you don’t know yourself, STFU.

Agree 100%. People post on here looking for others' experiences. If they want an answer from Google or AI then they'd go there - it'd be surprising if they hadn't already.

And if posters do quote from somewhere else, then the original source should be referenced.

Why do rear brake pads need replacing on a 2022 Ariya? Given it's an EV, surely the pads last a lot longer than 3-4 years of driving, due to the use of the regen. That's been my experience; the pads are hardly worn.

Simple, manufactures worked that out years ago and make the pads with less brake material to save money.

The electric motor mechanism is separate to the piston and must be wound back prior to using the pust back tool you linked. If not it either won't push back or is likely to ramage the mechanism.

A scan tool can command the car to do it of if you don't have one there are two other methods.

You can take off the motor and used a ratchet torx bit to retract back the adjustment mechanism
Or you can use a car battery and a couple of wires to power the motor the motor backwards.
I have done both these techniques on cars.

This video shows them.

After the motors are retracted you can then use the wind back tool to push back the piston.

Probably corrosion. The rear brakes do so little work on an EV that the disc surface doesn't get properly "cleaned" by the pads, consequently rust builds up and the surface becomes pitted.

My niro needed rear discs and pads at just under 3 years old/50000 miles due to the discs being badly corroded. The dealer did it under warranty as they measured barely any wear to the original pads.

A lot of the VW based EVs have drum brakes at the rear as they're better protected against moisture and corrosion than discs.
