Frozen brakes?

Has anyone experienced locked up rear wheels when using the parking brake in cold temperatures? Several times now, always in winter and parked overnight in below freezing temperatures, when I release the parking brake and put it in gear, the truck will not move. I park on an inclined driveway, backed in, and I like to set the parking brake. When the rear wheels lock, I use as much throttle as I comfortable can, keeping in mind that if and when the rear wheels break free, I need to be ready for the instant and significant acceleration that will happen. After some effort of switching between reverse and drive and trying to power out of it, I have so far been successful in freeing them. I want to believe that the problem has something to do with the brakes, but on one occasion I was able to drag a locked up wheel down the dry pavement and left a skid mark. That made me wonder if it was a transmission problem but that didn’t make sense given the specific environmental conditions required for this to happen. I have a 2019 2WD.

 

Yes, it's not uncommon, particularly if they were wet when parked for the evening.

Yep it happens to these trucks. I try not to use the parking brake if I know the drums are wet.

Also, if they do freeze, some people have bent their hub flanges trying for force the truck to move. I have not bent anything forcing it, but I have only had to do it twice before I learned my lesson.

 

And they produce rust annoying fast lock shoes to the drums.

 

yep happens to me up here in MN if I wash the truck and temps dip below 10 that night. I end up putting it in 4Lo with the rear locker and it busts through the ice. Not sure what the best way to deal with it is on your truck

 

Can you back your truck so a rear tire is resting on a wedged block? Then put it in Park and leave the Parking brake off.

 

Thanks to all the replies. The water to ice explanation is compelling and plausible. However, without the driving in precipitation or going through a car wash as sources of the water in the brakes, what’s left? Humidity? It just seems that this problem, “not uncommon”, is unacceptable. I have never had this happen on any of my other vehicles. And apparently, from 5nahalf’s response, it is potentially damaging. Wonder if Toyota was aware of this common issue and made a fix? I will talk to the local dealer and see what they say. I would pay for new rear brakes if it eliminates the problem.

 

Its more of a issue with drum brakes than a toyota issue.

Ok, I guess I’ve been spoiled then. I’ll check the link. Appreciate it.

 

Perhaps your prior vehicles had rear disc brakes; this might be the only "old-fashioned" vehicle you have had.
