Brakes are soft after caliper paint job (2024 CX-5)

⋯ I disconnected the positive battery connection, following another tip - no help.

Should it be removal of negative terminal from the battery to do the reset?

Common practice is you always remove the negative terminal the first from battery, and install the negative the last, to avoid accidental short to the car body.

If you didn't put it in maintenance mode, then you shouldn't have been able to push the rear piston back. The EPB motor would have prevented that. I'm surprised you were able to do that. Either way, the rear calipers are messed up now, so yeah, take it to the dealer and hopefully they can salvage things.
Keep us posted.

I did not need to push either rear piston. Only the right front one, slightly. Nevertheless, I am at dealer right now, will post results.

Interested to hear what they found?

I decided to take a look at my pads and I bled the brakes and refilled with about 40oz of DOT 3. Fortunately the rear pads still look pretty evenly worn. I'm not going to mess with them. I always do a little 'roll test' after using the EPB.
If I had purchased my CX5 a couple of months earlier I could have had the regular handbrake

Hello all, just joined. My better half just bought a 2024 CX-5 in that amazing red color. I bought the G2 caliper paint system, which turned out to be a perfect match! In order to paint them I removed the calipers, pads and clips. However, I did NOT disconnect any lines, (no air got in the system). I did have to compress one of the calipers slightly to get it back on the rotor, but maybe an 1/8th of an inch is all. Test drive: Brake pedal went to the floor. Drove it for a few minutes. They pump up somewhat, but are super soft the next time pedal is pressed. A (mechanic) friend on mine thinks it may be a system error that needs to be reset - "those dang computers" - LOL!
So, what's wrong and how do I fix it? THANKS!!

Hi all,
I came across 2 videos on youtube showing how to put vehicle on maintenance mode for rear caliper work. Hope it helps.
