Odd brake issue
Hey everyone this truly is an odd one. A handful of times after washing my car, using Adams Polishes wheel and tire cleaner on the wheels and tires and than parking it for a day or 2 the front brake calipers become stuck. When putting the car in reverse to leave the garage it take a lot of RPMs to get them "unstuck". And it almost becomes "unstuck" violently with a loud thud. Anyone else have this issues at all? The brakes function like they should afterwards. This has happened backing up and going forward.

its rather normal for the pad and rotor combo on these cars. That moisture is going to lock them up if parked right way and allowed to sit. Ive only had one time that it was particularly hard to break them loose. I use the Z26 street pad and it's much less than the OE Brembo pad.

There was a guy on the FB groups that recently just posted something similar. Part of brake pad got stuck to the rotor.
Not sure if you're part of the 6th Gen ZL1 FB group but here's the post. https://www.facebook.com/groups/7188...7752343722852/ I've never had this issue but I use Carbotech 1512 pads. |

Drive the car right after you wash it down, heat up the rotors / pads / calipers, or get some Atom-Mac and spray it on before you put it away.

Don't wash the tires and wheels when the brakes are hot. Also, it helps if you move the car after you wash it rather than just wash the car and leave it sit. I pull the car out of the garage and wash it cold, then move it back into the garage and I never have this issue.

Yep. This would happen on my last 3 cars, including this one. Just need to drive it around my cul-de-sac two or three loops before I park it in the garage.

Same, and I still have OEM pads. Never had an issue. I would guess it may be the type of wheel cleaner being used and that its being liberally sprayed on the rotors too and maybe not being washed off properly.

In my case, it's just water. Even if I just spray the car down with the pressure washer, it will do it. (I had the exact same thought and tested it.) Maybe it has to do with hard or soft water?

I think it could have something to do with it. I wash my car with only deionized water and then it sits for days, up to two weeks. There is visible rust on the rotors, but they have never seized to the pads.
