What temp does brake fluid freeze?
As I said what temp does brake fluid freeze?
My ABS and Emergency brake light came on.
But the speedo kept workin. I drove home, but when I hit the brakes they locked up.
I went out today and no lights no probs . ABS is even workin again.
What the heck could it have been cold enuff outside last night to freeze the brake fluid?
It was like -18 last night .
The only other thing I can think of is sensor ,but why would it clear itself so quickly?
Any response would be great guy's

As long as you don't have water in the line then I've had my brake fluid work well at -29 below zero. I'm not talking wind chill effect but if you want it then the temps was in the -45 below zero range, nice and warm and not fit for man or beast [&:]

Is there a chance that I have water in the form of moisture in the line?
If so maybe I need to bleed my brakes and that old nasty crap out of there.

RE: What temp does brake fluid freeze?
According to the Car Care Council, brake fluid in the typical vehicle can become contaminated in two years or less. This is because the fluid absorbs moisture, which works its way through the hydraulic system. Under heavy braking conditions, such as encountered in mountainous or hilly driving or when towing a trailer, moisture in the overheated fluid vaporizes (boiling point of water is lower than that of brake fluid) and braking efficiency is reduced. Even under normal driving circumstances, this condition can develop if the brake fluid is seriously contaminated. Not only is the contaminated fluid vulnerable to vaporizing, it also can freeze.

RE: What temp does brake fluid freeze?
I knew it,
Thanks for the info sabersix
When I got the truck I went though it pretty good
but the brakes looked good and I didn't think about checkin the fluid.
I guess this is what I get for not being skeptical of some one elses handy work.

RE: What temp does brake fluid freeze?
I think brake fluid is probably the MOST neglected fluid. If you change out old brake fluid, you will notice a big difference in braking action. Note, change NOT top off. Probably the reason brake fluid is neglected is because it is so difficult, messy, and time consuming to change. There is no drain plug and that stuff goes everywhere (not to mention that it will eat up any painted surfaces). Then once you get the old stuff out you have to purge the air from the system. Blah, no thanks. It is almost worth taking to the *gasp* dealer...

RE: What temp does brake fluid freeze?
Brake fluid is a sponge with water.An open can will absorb moisture and it will lower the boiling point which it states on the back of the can and I suppose it could freeze no idea at what temp though.
I purchased my first CTD in 1990 and still have it. Whenever I do a brake job I push all the calipers in then suckall the old fluid out with an old turkey baster of sorts and refill with new fluid. Doing this during every brake job removes moisture from the system and keeps it clean. I do this with all my vehicles and I have never replaced a master cylinder or had an ABS problem. It'scheap insurance.
No different than changing your engine or transmission oil.
