2018 991.2 Brake issue
I have a CPO 911 Carrera S that I recently purchased out of . Last weekend I washed the car including the wheels then immediately put it back in the garage. Yesterday I want to take it out and it almost seemed like the front brakes were seized/ frozen and holding back the car from moving. It took a little bit of accelerator depression while in reverse to finally break free and get it out of the garage. Now it seems the brakes are making some sort of ticking sound when they are pressed while driving. It has definitely gotten quieter after some miles of driving however I’m dreading having to bring it to the dealership.do you think a rotor or pad was damaged? Car only has 6k miles on it. Would this be covered. Any insight would be greatly appreciated.

It’s perfectly normal. I’d guess you’re new to hand washing cars. This happens pretty much after every wash if you park it with wet disks and let them dry. I’ve been hand washing cars for 40 years and what you describe happens every time if you just park it and let it dry completely. The sound you hear will disappear. It’s just surface rust. To avoid it, just drive it before the disks are completely dry. You haven’t hurt anything.

It could be that you picked up a pebble (unrelated to the washing and pads sticking) and it’s caught between your disk and rotor. That’s a fairly common occurrence. Look at your disks and see if you notice anything. You don’t need to remove the wheels; just look through the spokes. If there is something caught, you may see a thin circular mark where the pebble is scratching. But if you see nothing, I’d expect that it is really small and will disintegrate quickly as you drive it more. If you see that a fine groove is starting to form, then you should probably remove the stuck particle, but I honestly think it’s unnecessary, unless you see a pronounced groove.

Torque wrench
breaker bar
Jack stand (I rest the caliper on this)
Floor Jack (best to have another jack stand for safety)
Jack puck
Socket for lug (19mm?)
T55 for the caliper bolts (I think)
if this is the front of the car you'll have one additional bracket to undo, 10mm socket
flathead screw driver to get the ABS clip off (be careful as they can break)
Don't pull the pads or you'll have to deal with break wear sensor. Cheap to replace but hard to get out without damaging. Again, no need to pull them out anyway
I have caliper and wheel studs so double check the sizes - I believe they are correct.

This is a normal reaction after washing and immediately parking the car. The longer the car sits the more the rust builds up (to a certain extent). So, as it was a week sitting since you washed and parked, quite a bit of rust developed, and the brake pads have seized to the rotors. As a result, it may take quite a number of braking cycles to remove all that rust. As stated above. This is normal operation.

put new rotors and pads and the wife's SUV last year and even with just a few thousand miles on them if I leave the car in the driveway for a few days and it rains a lot it will rust and grind next time it is driven until it wears off.

I think this might explain a crunch like sound I have heard pulling out of my garage. I washed my car in the driveway, pulled about 10 feet forward into the garage and dried the car off. A week later I started the car, put it in reverse and as I released the brakes to back up it makes a sort of crunch sound as it starts to move. Not when the transmission is engaged but when the car begins to move. Only happens when there is a coat of rust on the rotors after a wash when it is just parked and not moved for a day or two. It just as the wheels start to rotate, then everything is normal. Does this make sense? It wasn't until I read this thread that I realized what was happening.

Thanks as it was a little shocking. Only happened a couple times but this thread made the light bulb in my head go off and I realized. It was always after a wash when left parked with wet brakes for a couple days.
