993/907 posted the following a few weeks back;
Well, after getting to play for a couple hours last night in some fresh snow I found my rotors locked up tight this AM.

I'd rather not whack them with a steel bar if I can avoid it, is there another way? Temps are around 20F, would just pouring some lukewarm water on the calipers do the trick?

Thanks.

This only happened to my 993 when it was really, really cold out and enough snow on the road to pack the rims full of snow. Since mine was only a C2, my front wheels/brakes iced up. If you have a C4 I cant see this happening

I was lucky and that I only had one of them ice up but I had to drive 5 miles with one of my wheels locked solid to a snow free road that had enough grip to brake my wheel loose. It was 1am so I was not to creative at that time to think of other solutions

As for tips, I dont have any. Maybe carry a little propane torch that you could carry in the trunk. You could also use hot water then hop in the car and get driving

I'd substitute a wooden dowel or 2x2 for the steel rod....and wont' stick to your hand if it gets a little damp at those temps. Like herman maire says above, you can use the hot water, but have to get in and drive off before they re-freeze.

Yup, I'm running the Cup-IIs and they were packed solid at the end of the drive. I cleared the snow out as best I could (still there this afternoon, never got above 24F today,) and will see if that helps tomorrow.

Why would a C4 not have this issue?

I think I will try the water first and if that doesn't do it I have a fiberglass hammer with a rubber handle, I will use that instead of the steel bar and tap it with a mallet.

Thanks for your reply, and thanks to Gordo for posting his note in the first place. I was only confused for a few seconds upon finding my car in this condition, immediately thought of his posts on the topic.

Thanks!

What about the De-Icer product spray? It works great on my door locks on the winter here in CO when its really cold. Seems to de-ice and lubricate all in one...It's a thought

Try water mixed with rubbing alcohol and vinegar - about 1 cup each in a squirt bottle. Works great on windshields as well.

That may work well for door locks but you probably don't want to "lubricate" your brakes......

Do what I do, keep it in the garage!! Hey Ryan, sorry we didn't get to meet up this year I was crazy busy. Are you driving your car this winter or storing?

And I heard using windshield washer fluid was an option to de-ice the brakes. Its pretty much diluted alcohol anyways.

Strange. I drove my first C2 for at least 4 winters in Boston and never had this happen. Had Cup 2s on it as well. Many have seen this picture of it before:

Hey Chris,
I am definetely storing the car for the winter. I have a heated garage so it will be toasty warm for the majority of the winter months. I do have to take it i=to my mechanic soon for the 60K service, oh and maybe I will just order the Stage III fister exhaust while its in the shop.

Heat gun, windshield washer fluid could work.

Minus 25f here today, not driving the 993, however have never had an issues with any car regarding the calipers/rotors freezing.

Spidey 993

Yep, see there, it's confirmed..I should never work on a car let alone give advice to others on theirs. I will stick to driving them

I feel for you brother! Although it was +10 and sunny here this afternoon - your weather is coming our way soon...

This may or may not be related, but it is worth mentioning.

If I wash my car and then garage her without a drive, I noticed my brakes tend to lock even in a hot Sydney summer, the rotors develop a film of rust even while washing it. It is enough to be unable to push the car but I can drive it. There is a small thud as the rotor breaks free but then all is well, of course there is no reduced tyre grip like there is in snow.

I thought I'd mention it as your brake rotor freeze may possibly be related to the same corrosion rather than the very low temps, especially seeing as they break free with an impact on the rotor.

Just a thought, may be worth considering.

And you can have it Calgary was the Second coldest place on earth yesterday, second to Antarctica
